A Novel Technique to Enhance the Lifetime of Wireless Sensor Networks through...IJECEIAES
In the most of the real world scenarios, wireless sensor networks are used. Some of the major tasks of these types of networks is to sense some information and sending it to monitoring system or tracking some activity etc. In such applications, the sensor nodes are deployed in large area and in considerably large numbers [1]-[3]. Each of these node will be having constrained resources whether it might be energy, memory or processing capability. Energy is the major resource constraint in these types of networks. Hence enough care to be taken in all aspects such that energy can be used very efficiently. Different Activities which will be taking place in a sensor node are sensing, radio operations and receiving and computing. Among all these operations, radio consumes maximum power. Hence there is a need of reducing the power consumption in such radio operations. In the proposed work a software module is developed which will reduce the number of transmissions done to the base station. The work compares the consecutively sensed data and if these data are same then the old data then the old data will be retained. In other case the newly sensed data will be sent to the sink node. This technique reduces the number of data transmissions in a significant way. With the reduced number of transmissions, the energy saved in each node will be more, which will increase the lifetime of the entire network.

Wireless sensor networks (WSN) is composed of a large number of small nodes with limited functionality.
The most important issue in this type of networks is energy constraints. In this area several researches have
been done from which clustering is one of the most effective solutions. The goal of clustering is to divide
network into sections each of which has a cluster head (CH). The task of cluster heads collection, data
aggregation and transmission to the base station is undertaken. In this paper, we introduce a new approach
for clustering sensor networks based on Particle Swarm Optimization (PSO) algorithm using the optimal
fitness function, which aims to extend network lifetime. The parameters used in this algorithm are residual
energy density, the distance from the base station, intra-cluster distance from the cluster head. Simulation
results show that the proposed method is more effective compared to protocols such as (LEACH, CHEF,
PSO-MV) in terms of network lifetime and energy consumption.

To reduce such issues the knowledge of futuristic weather conditions and wind speed trend are required. This work mainly describes the implementation of NARX Artificial neural network for wind speed & power forecasting with the help of historical data available from wind farms.
Data Accuracy Models under Spatio - Temporal Correlation with Adaptive Strate...IDES Editor
Wireless sensor nodes continuously observe and
sense statistical data from the physical environment. But what
degree of accurate data sensed by the sensor nodes
collaboratively is a big issue for wireless sensor networks.
Hence in this paper, we describe accuracy models of sensor
networks for collecting accurate data from the physical
environment under two conditions. First condition: we propose
accuracy model which requires a priori knowledge of statistical
data of the physical environment called Estimated Data
Accuracy (EDA) model. Simulation results shows that EDA
model can sense more accurate data from the physical
environment than the other information accuracy models in
the network. Moreover using EDA model, there exist an
optimal set of sensor nodes which are adequate to perform
approximately the same data accuracy level achieve by the
network. Finally we simulate EDA model under the thread of
malicious attacks in the network due to extreme physical
environment. Second condition: we propose another accuracy
model using Steepest Decent method called Adaptive Data
Accuracy (ADA) model which doesn’t require any a priori
information of input signal statistics. We also show that using
ADA model, there exist an optimal set of sensor nodes which
measures accurate data and are sufficient to perform the same
data accuracy level achieve by the network. Further in ADA
model, we can reduce the amount of data transmission for
these optimal set of sensor nodes using a model called Spatio-
Temporal Data Prediction (STDP) model. STDP model
captures the spatial and temporal correlation of sensing data
to reduce the communication overhead under data reduction
strategies. Finally using STDP model, we illustrate a
mechanism to trace the malicious nodes in the network under
extreme physical environment. Computer simulations
illustrate the performance of EDA, ADA and STDP models
respectively.

THRESHOLD BASED DATA REDUCTION FOR PROLONGING LIFE OF WIRELESS SENSOR NETWORKpijans
ABSTRACT
Wireless sensor network is a set of tiny elements i.e. sensors. WSN is used in the field of Health Monitoring, Civil Construction, Military Applications and Agricultural etc., for monitoring environmental parameters.The WSN is having the challenges like less processing power, less memory, less bandwidth and battery
powered. The data monitored through the sensors would be sent to the sink for data processing. The data sent from sensor node can be controlled for saving the energy, as maximum energy is consumed for transmission of data and it is not possible to replace the batteries frequently. In this work threshold based and adaptive threshold based data reduction techniques with energy efficient shortest path are used for minimizing the energy of sensor node and the network. Adaptive approach saves energy and reduce data by 30% to 40% as compared to threshold based approach.
An Analytical Model of Latency and Data Aggregation Tradeoff in Cluster Based...ijsrd.com
Sensor networks are collection of sensor nodes which co-operatively send sensed data to base station. As sensor nodes are battery driven, an efficient utilization of power is essential in order to use networks for long duration. Therefore it is needed to reduce data traffic inside sensor networks, thereby reducing the amount of data that is needed to send to base station. The main goal of data aggregation algorithms is to gather and aggregate data in an energy efficient manner so that network lifetime is enhanced. In wireless sensor network, periodic data sampling leads to enormous collection of raw facts, the transmission of which would rapidly deplete the sensor power. A fundamental challenge in the design of wireless sensor networks (WSNs) is to maximize their lifetimes. Data aggregation has emerged as a basic approach in WSNs in order to reduce the number of transmissions of sensor nodes, and hence minimizing the overall power consumption in the network. Data aggregation is affected by several factors, such as the placement of aggregation points, the aggregation function, and the density of sensors in the network. In this paper, an analytical model of wireless sensor network is developed and performance is analyzed for varying degree of aggregation and latency parameters. The overall performance of our proposed methods is evaluated using MATLAB simulator in terms of aggregation cycles, average packet drops, transmission cost and network lifetime. Finally, simulation results establish the validity and efficiency of the approach.
Mobile Agents based Energy Efficient Routing for Wireless Sensor NetworksEswar Publications
Energy Efficiency and prolonged network lifetime are few of the major concern areas. Energy consumption rated of sensor nodes can be reduced in various ways. Data aggregation, result sharing and filtration of aggregated data among sensor nodes deployed in the unattended regions have been few of the most researched areas in the field of wireless sensor networks. While data aggregation is concerned with minimizing the information transfer from source to sink to reduce network traffic and removing congestion in network, result sharing focuses on sharing of information among agents pertinent to the tasks at hand and filtration of aggregated data so as to remove redundant information. There exist various algorithms for data aggregation and filtration using different mobile agents. In this proposed work same mobile agent is used to perform both tasks data aggregation and data filtration. This approach advocates the sharing of resources and reducing the energy consumption level of sensor nodes.
A COST EFFECTIVE COMPRESSIVE DATA AGGREGATION TECHNIQUE FOR WIRELESS SENSOR N...ijasuc
In wireless sensor network (WSN) there are two main problems in employing conventional compression
techniques. The compression performance depends on the organization of the routes for a larger extent.
The efficiency of an in-network data compression scheme is not solely determined by the compression
ratio, but also depends on the computational and communication overheads. In Compressive Data
Aggregation technique, data is gathered at some intermediate node where its size is reduced by applying
compression technique without losing any information of complete data. In our previous work, we have
developed an adaptive traffic aware aggregation technique in which the aggregation technique can be
changed into structured and structure-free adaptively, depending on the load status of the traffic. In this
paper, as an extension to our previous work, we provide a cost effective compressive data gathering
technique to enhance the traffic load, by using structured data aggregation scheme. We also design a
technique that effectively reduces the computation and communication costs involved in the compressive
data gathering process. The use of compressive data gathering process provides a compressed sensor
reading to reduce global data traffic and distributes energy consumption evenly to prolong the network
lifetime. By simulation results, we show that our proposed technique improves the delivery ratio while
reducing the energy and delay
SENSOR NETWORKS BASED ON DISTRIBUTED WIRELESS SENSINGIJARIDEA Journal
Abstract— Exponential data transfer capacity scaling has been an essential driver of the development and fame of the Internet. Nonetheless, increments in transmission capacity have been joined by increments in power utilization, and in spite of maintained framework plan endeavors to address control request, noteworthy mechanical difficulties remain that debilitate to moderate future data transfer capacity development. In this paper we depict the power and related warmth administration challenges in today's switches. We advocate a wide way to deal with tending to this issue incorporates making power-mindfulness an essential target in the plan and setup of systems, and in the outline and usage of system conventions. We bolster our contentions by giving a contextual analysis of force requests of two standard switch stages that empowers us to make a non specific model for switch control utilization. We apply this model in an arrangement of target system setups and utilize blended whole number enhancement strategies to explore control utilization, execution and strength in static system outline and in element steering. Our outcomes show the potential for huge power reserve funds in operational systems by including power-mindfulness.

Wireless communication without pre shared secrets using spread spectrum techn...eSAT Journals
Abstract
The wireless communication using spread spectrum relies on the assumption that some secret is shared among source and
destination node before communication or transmission has started. This problem is called the circular dependency problem
(CDP). This CDP exists in large networks, where nodes frequently join and leaves the network. In this work we have introduced
an efficient and reliable mechanism called Advanced Encryption Standard (AES) Algorithm, to overcome circular dependency
problem (CDP). This is an efficient algorithm to make successful transmission of data without pre-sharing any secret key. We
have evaluated this by simulation in Matrix Laboratory (MATLAB).
Keywords: -Spread spectrum, CDP, AES and MATLAB.
Data collection algorithm for wireless sensor networks using collaborative mo...IJECEIAES
The simplest approach to reduce network latency for data gathering in wireless sensor networks (WSN) is to use multiple mobile elements rather than a single mobile sink. However, the most challneging issues faced this approach are firstly the high network cost as a result of using large number of mobile elements. Secondly, it suffers from the difficulty of network partitioning to achieve an efficient load balancing among these mobile elements. In this study, a collaborative data collection algorithm (CDCA) is developed. Simulation results presented in this paper demonstrated that with this algorithm the latency is significantly reduced at small number of mobile elements. Furthermore, the performance of CDCA algorithm is compared with the Area Splitting Algorithm (ASA). Consequently, the CDCA showed superior performance in terms of network latency, load balancing, and the required number of mobile elements.
Feasibility of an eco – friendly disposal method for Iron ore tailingstheijes
The greatest challenge ahead of the Iron ore mining industry is to tackle the issues related to management of tailings. The tailing disposal and storage methods are sensitive to the environment and care must be taken to keep them at the helm. The method being practiced for disposing the tailings is as thickener underflow at around 45% solids. The development of paste thickener & deep cone thickener are encouraging and can dispose tailings at around 65% solids. However, they are yet to be established over different range of mineral tailings and also the economic aspects related to their transportation are yet to be resolved. Thus the development of improved tailing disposal system is of paramount importance and need of the hour. Filtration of tailings after thickening is an alternative to current practices. However, the suitability of this application is to be assessed for tailings of different nature. In this perspective an attempt has been made to assess the filterability of tailings generated from beneficiation of slimes from Donimalai area. From the studies it is evident that the application of filtration process to these tailings is encouraging. By adopting pressure filtration technique it was possible to produce filtered tailings with moisture in the range of 16 - 21%. It is possible to get the filtration rate in the range of 200 – 300 Kg/hr/m2 while operating in the aforesaid moisture range. The greatest advantage ascertained is in the reduction in volume of tailings to be disposed by around 63% which is significant apart from increase in the water recovery by about 10%.
An Evaluation of the Impact of Government Assisted Housing Programmes (GAHPs)...theijes
Housing investment has been considered as a major contributor to economic growth with many social and economic benefits. This research work was carried out to evaluate the impact of Government Assisted Housing Programmes (GAHPs) in Bauchi State. The methodology employed were Oral interview, Self-assessment, Checklist and Questionnaires. Two target groups were considered for this research: the first group was construction professionals such as Architects, Engineers, Quantity surveyors, Builders and Service Engineers involved in the construction of such housing programmes, while the second group was family heads/occupants of government housing programmes. The research was conducted using completed Tambari housing estate and 1000-units of two bedrooms semi-detached / three bedrooms under construction at Dungal as case studies. The information obtained from these case studies were analysed using relative index, linear correlation, regression and one - way ANOVA (Analysis of variance). The research revealed that the first five critical impact of housing programmes were employment for skilled and unskilled workers (RI = 0.77); increase demand for building materials market (RI =0. 75); Generates income and employment in a number of related /non-related industry (RI = 0.75); increases income to land owners due to compensation paid for land acquisition (RI=0.74) and attracts infrastructural facilities to such localities (RI = 0.72). It also revealed that most of the respondents were satisfied with the impact of GAHPs within their vicinity.
This paper presents artificial intelligence approach of artificial neural network (ANN) and random forest (RF) that used to perform short-term photovoltaic (PV) output current forecasting (STPCF) for the next 24-hours.

While data aggregation is concerned with minimizing the information transfer from source to sink to reduce network traffic and removing congestion in network, result sharing focuses on sharing of information among agents pertinent to the tasks at hand and filtration of aggregated data so as to remove redundant information. There exist various algorithms for data aggregation and filtration using different mobile agents. In this proposed work same mobile agent is used to perform both tasks data aggregation and data filtration. This approach advocates the sharing of resources and reducing the energy consumption level of sensor nodes.
A COST EFFECTIVE COMPRESSIVE DATA AGGREGATION TECHNIQUE FOR WIRELESS SENSOR N...ijasuc
In wireless sensor network (WSN) there are two main problems in employing conventional compression
techniques. The compression performance depends on the organization of the routes for a larger extent.
The efficiency of an in-network data compression scheme is not solely determined by the compression
ratio, but also depends on the computational and communication overheads. In Compressive Data
Aggregation technique, data is gathered at some intermediate node where its size is reduced by applying
compression technique without losing any information of complete data. In our previous work, we have
developed an adaptive traffic aware aggregation technique in which the aggregation technique can be
changed into structured and structure-free adaptively, depending on the load status of the traffic. In this
paper, as an extension to our previous work, we provide a cost effective compressive data gathering
technique to enhance the traffic load, by using structured data aggregation scheme. We also design a
technique that effectively reduces the computation and communication costs involved in the compressive
data gathering process. The use of compressive data gathering process provides a compressed sensor
reading to reduce global data traffic and distributes energy consumption evenly to prolong the network
lifetime. By simulation results, we show that our proposed technique improves the delivery ratio while
reducing the energy and delay
SENSOR NETWORKS BASED ON DISTRIBUTED WIRELESS SENSINGIJARIDEA Journal
Abstract— Exponential data transfer capacity scaling has been an essential driver of the development and fame of the Internet. Nonetheless, increments in transmission capacity have been joined by increments in power utilization, and in spite of maintained framework plan endeavors to address control request, noteworthy mechanical difficulties remain that debilitate to moderate future data transfer capacity development. In this paper we depict the power and related warmth administration challenges in today's switches. We advocate a wide way to deal with tending to this issue incorporates making power-mindfulness an essential target in the plan and setup of systems, and in the outline and usage of system conventions. We bolster our contentions by giving a contextual analysis of force requests of two standard switch stages that empowers us to make a non specific model for switch control utilization. We apply this model in an arrangement of target system setups and utilize blended whole number enhancement strategies to explore control utilization, execution and strength in static system outline and in element steering. Our outcomes show the potential for huge power reserve funds in operational systems by including power-mindfulness.

Wireless communication without pre shared secrets using spread spectrum techn...eSAT Journals
Abstract
The wireless communication using spread spectrum relies on the assumption that some secret is shared among source and
destination node before communication or transmission has started. This problem is called the circular dependency problem
(CDP). This CDP exists in large networks, where nodes frequently join and leaves the network. In this work we have introduced
an efficient and reliable mechanism called Advanced Encryption Standard (AES) Algorithm, to overcome circular dependency
problem (CDP). This is an efficient algorithm to make successful transmission of data without pre-sharing any secret key. We
have evaluated this by simulation in Matrix Laboratory (MATLAB).
Keywords: -Spread spectrum, CDP, AES and MATLAB.
Data collection algorithm for wireless sensor networks using collaborative mo...IJECEIAES
The simplest approach to reduce network latency for data gathering in wireless sensor networks (WSN) is to use multiple mobile elements rather than a single mobile sink. However, the most challneging issues faced this approach are firstly the high network cost as a result of using large number of mobile elements. Secondly, it suffers from the difficulty of network partitioning to achieve an efficient load balancing among these mobile elements. In this study, a collaborative data collection algorithm (CDCA) is developed. Simulation results presented in this paper demonstrated that with this algorithm the latency is significantly reduced at small number of mobile elements. Furthermore, the performance of CDCA algorithm is compared with the Area Splitting Algorithm (ASA). Consequently, the CDCA showed superior performance in terms of network latency, load balancing, and the required number of mobile elements.
Feasibility of an eco – friendly disposal method for Iron ore tailingstheijes
The greatest challenge ahead of the Iron ore mining industry is to tackle the issues related to management of tailings. The tailing disposal and storage methods are sensitive to the environment and care must be taken to keep them at the helm. The method being practiced for disposing the tailings is as thickener underflow at around 45% solids. The development of paste thickener & deep cone thickener are encouraging and can dispose tailings at around 65% solids. However, they are yet to be established over different range of mineral tailings and also the economic aspects related to their transportation are yet to be resolved. Thus the development of improved tailing disposal system is of paramount importance and need of the hour. Filtration of tailings after thickening is an alternative to current practices. However, the suitability of this application is to be assessed for tailings of different nature. In this perspective an attempt has been made to assess the filterability of tailings generated from beneficiation of slimes from Donimalai area. From the studies it is evident that the application of filtration process to these tailings is encouraging. By adopting pressure filtration technique it was possible to produce filtered tailings with moisture in the range of 16 - 21%. It is possible to get the filtration rate in the range of 200 – 300 Kg/hr/m2 while operating in the aforesaid moisture range. The greatest advantage ascertained is in the reduction in volume of tailings to be disposed by around 63% which is significant apart from increase in the water recovery by about 10%.

This study was conducted in capital city of Kendari, Southeast Sulawesi, Indonesia. The study objectives were to find out factors that cause the poverty of the unattended poor in urban areas as well as to determine the most appropriate form of intervention suiting their condition. The research method was case study with qualitative approach through in-depth interview. Sampling was done through snowball sampling technique. The number of sample saturated after the informant reached 10 persons. The research population was the urban poor working as beggars, scavengers, and casual labourers. They live and earn a living in the city of Kendari. To obtain reliable data the research used sources triangulation, time triangulation, and techniques triangulation. The results of the study were as follows: (1) The unattended urban poor in this region are poor people, most of whom are poor of property, poor of knowledge, poor of morals and poor of faith (religion). They are poor of faith for not performing the command of God and performing activities prohibited by Allah instead; (2) The unattended urban poor in this region are those who suffer structural poverty as they have no access to decent work, receive no attention from the government and rich people nearby as well as often beyond the reach of formal assistance structure. In addition, they accept zakah (alms-giving) or social aid as sympathy to survive; (3) The unattended urban poor in this area are commonly coming migrants who do not possess production factors of land unless their workforce only; (4) A few of the unattended urban poor in this region is culturally poor since they do not want to be regulated, be lazy and disobedient and it accounts for why some of them survive by expecting the mercy of others, even stealing and taking away the rights of others; (5) The unattended urban poor in this region are those who are in need of both psychological and social empowerment in terms of knowledge, mental and faith.
In the process of drilling wells or carrying out treatment operations on the wells, the characteristics of the reservoir around the vicinity of the well changes due to the invasion of fluid when compared to zones further away in the reservoir. During the stimulation exercise, there is an increased tendency of emulsion formation with the acid concentration and in reality, most crude oils contain natural chemicals which frequently act to stabilize emulsions formed with acid or with spent acid and this severely hinders production due to the high viscosities inherent with emulsions and also, some crude oils chemically react with hydrochloric acid to form solid or semi-solid particles called asphaltene sludge. This can restrict or completely plug the flow channels in the producing formation thereby reducing the effectiveness of the acid treatment and also due to its insoluble in most treating solutions. In this study, pressure transient analysis was performed on well J8 and K35 of an oil field in the Niger Delta to determine the extent of formation damage around the wellbore, a pre and post evaluation on the stimulation job to ascertain the efficacy of the stimulation job is also presented. Result show that it is very important to determine the type of skin on each well, this well help in knowing the type of solution to the problem in order to increase the well’s productivity because a well whose skin is due to completion, partial penetration or slanting of well does not require stimulation and if the field’s operators go ahead to stimulate, they will only end up in wasting time and money without achieving any result because these skin cannot be removed by stimulation.
Enhancing the Performance of 75mw Steam Power Plant with Second Law Efficienc...theijes
Energy analysis, thermodynamic second law and Rankine cycle are universal method for enhancing the performance of power plant. Experimental data of 75MW power plant was obtained, mass; energy balance and thermodynamic second law were used to analysis the exergy efficiency while Rankine cycle was used to calculate the overall efficiency of the plant as well as varying the condenser pressure. Results obtained showed that an increase in the reference environment temperature increases the thermal, Rankine and exergy efficiency of the plant. Also as the condenser pressure increases, the efficiency of the plant decreases. The condenser pressure must be reduced in order to decrease the cause's irreveribilities in the system. Also, the plant should be operated above 50% of the operating capacity of the plant, to minimize wastage of energy consumption because more energy will be generated in the boiler even when not in used.
Micro Mechanical Modeling of Fiber / Epoxy Unidirectional Laminates Using Featheijes
The focus of the study was to develop the micromechanical model associated with proper damage model to predict the overall mechanical behavior of fiber/matrix unidirectional laminates. The present and first investigation studies the influence of fiber-matrix interface on the behaviour of fiber reinforced composite lamina using micromechanical models. Mechanical properties E1 and E2 are determined at various volume fractions. The second investigation studies the micro-thermo elastic behaviour of the square unit cell of a hybrid fiber reinforced composite lamina. Later this model is extended to predict the coefficients of thermal expansion of graphite-boron hybrid fiber reinforced lamina for various volume fractions.In the third investigation, an analytical solution of the thermal stresses for a fiber embedded in a matrix is presented based on the idea of the finite element and under some simplifying assumptions. The analytical solution to the problem is found for the case when the length of the embedded bar (fiber) is much greater than its radius, and the Young's modulus of the matrix is much less than that of the fiber. The problem is also solved numerically by means of finite element analysis using ANSYS 10.0. Both results are compared and it is shown that both approaches coincide very close qualitatively and quantitatively although significant discrepancies may appear at specific points for specific cases. For all above three cases 3-D finite element models have been developed from the representative volume elements of the composite which are in the form of square unit cells. The finite element software ANSYS 10.0 has been successfully executed to evaluate the properties

Underground Water Quantity and Quality Assessment in Next Decade in Bilaspur ...theijes
---------------------------------------------------------------ABSTRACT------------------------------------------------------
Water is most essential to life next to air and food. It is rather a part of life as the protoplasm of most living
cells contain about 80% water and any major reduction in this percentage is highly detrimental. Over 70% of
earth surface is covered with oceanic water which accounts of 97.2% of the total water resources present on the
earth. Ocean water although , is not utilizable by man directly but it is useful in some of man’s activities like
navigation and renewable energy sources for welfare of mankind The water which is essential to human life is
the fresh water and it is 2.8% of the total water resources on the planet earth. Population growth and
uncontrolled urbanization have created a water crisis in India, our lakes and ponds were once a natural way of
recharging groundwater, but they are being destroyed through urbanisation.Our sewage goes untreated , so the
rivers are contaminated. We used to be very good at managing water in India, but we are losing that ability . As
a consequence of this increased groundwater withdrawl and erratic monsoon , the groundwater levels are
decling in many parts of India including Madhya Pradesh as well as in Chhattisgah region. The rapid growth of
industrialization and urbanisation is the major cause of exploitation of groundwater on and average the
groundwater level in Bilaspur city gone upto 30 feet down. Many places in the city, corporation people required
in the summer season to down pump-motors due to down level of ground water. In the previous year, some
places like Hemunagar and Chuchuhiapara, water level gone down to 30 feet and Bhartinagar, Nehrunagar, Juna
Bilaspur, Sarkanda shown 10-15 feet more down of water level. It is being observed that this trend is followed
year by year. The people of Bilaspur known that earlier when the Arpa river was not it in course, even though
the ground water was available at 20-30 feet very easily. Due to drying of river, the underground water level of
Bilaspur is going down day by day, which is appearing as major problem to the growing population. By and
large the growing city like Bilaspur in Chhattisgarh district is facing the problem of underground water present
day and will be faced severe crisis in next decade. But the quality of underground water as data reveals that it is
still remain same as was previous decades. Of course, the water quantity required for future can be managed
through surface water by managing and saving river water from the encroachment and pollution.

A Wireless Sensor Network includes the distributed sensor nodes using limited energy, to monitor the physical environments and forward to the sink node. Energy is the major resource in WSN for increasing the network lifetime. Several works have been done in this field but the energy efficient data gathering is still not improved. In order to amend the data gathering with minimal energy consumption, an efficient technique called chaotic whale metaheuristic energy optimized data gathering (CWMEODG) is introduced. The mathematical model called Chaotic tent map is applied to the parameters used in the CWMEODG technique for finding the global optimum solution and fast convergence rate. Simulation of the proposed CWMEODG technique is performed with different parameters such as energy consumption, data packet delivery ratio, data packet loss ratio and delay with deference to dedicated quantity of sensor nodes and number of packets. The consequences discussion shows that the CWMEODG technique progresses the data gathering and network lifetime with minimum delay as well as packet loss than the state-of-the-art methods.

Abstract
Recently, several data aggregation schemes based on privacy homomorphism encryption have been proposed and investigated on wireless sensor networks. These data aggregation techniques provide higher security compared with traditional aggregation since cluster heads (aggregator) can directly aggregate the cipher texts without decryption; consequently, transmission overhead. Data aggregation protocol can reduce the communication cost, so the life time of sensor network is extended. The structure based has the overhead in dynamic scenarios for any event based application. The goal of our work is to design techniques and protocol that is structure free and ensure data integrity and aggregation with low transmission overhead and transmission cost. Experiment results demonstrate that the transmission overhead is still reduced even if on sensing data. Further, the design has been generalized and adopted in wireless sensor networks.
DATA GATHERING ALGORITHMS FOR WIRELESS SENSOR NETWORKS: A SURVEYijasuc
Recent developments in processor, memory and radio technology have enabled wireless sensor networks
which are deployed to collect useful information from an area of interest. The sensed data must be
gathered and transmitted to a base station where it is further processed for end-user queries. Since the
network consists of low-cost nodes with limited battery power, power efficient methods must be employed
for data gathering and aggregation in order to achieve long network lifetimes. In an environment where in
a round of communication each of the sensor nodes has data to send to a base station, it is important to
minimize the total energy consumed by the system in a round so that the system lifetime is maximized. With
the use of data fusion and aggregation techniques, while minimizing the total energy per round, if power
consumption per node can be balanced as well, a near optimal data gathering and routing scheme can be
achieved in terms of network lifetime. Several application specific sensor network data gathering protocols
have been proposed in research literatures. However, most of the proposed algorithms have been some
attention to the related network lifetime and saving energy are two critical issues for wireless sensor
networks. In this paper we have explored general network lifetime in wireless sensor networks and made an
extensive study to categorize available data gathering techniques and analyze possible network lifetime on
them.
Embedding Wireless Intelligent Sensors Based on Compact Measurement for Struc...IJMTST Journal
In wireless data transfer, the loss of information is an important factor that reduces the power of wireless
sensor networks. In many engineering application programs, especially civil structures, data loss recovery
algorithms are required to maintain the required strength. The main objective of the present study is to
investigate the integration of intelligent wireless sensors based on compact measurements for structural
health monitoring using the improved CS-based data loss recovery algorithm. For this purpose, an improved
algorithm based on randomized demography (RD) has been used to solve the problem of traditional
algorithms in data loss of microcontroller dependence. The results show that for complex computing, the
traditional algorithms require more memory and higher accuracy, while the improved algorithm has low-level
features and requires medium memory and accuracy.

The main motive of this research is to study energy-efficient data-gathering mechanisms to
abnormal packet data for saving the energy. To detect the abnormal packet irregularities is useful for
saving energy, as well as for management of network, because the patterns found can be used for
both decision making in applications and system performance tuning. Node distribution in WSNs is
either deterministic or self-organizing and application dependant. The sensor nodes in WSNs have
minimum energy and they use their energy for communication and sensing.

Optimal Coverage Path Planningin a Wireless Sensor Network for Intelligent Tr...IJCNCJournal
With the enhancement of the intelligent and communication technology, an intelligent transportation plays a vital role to facilitate an essential service to many people, allowing them to travel quickly and conveniently from place to place. Wireless sensor networks (WSNs) are well-known for their ability to detect physical significant barriers due to their diverse movement, self-organizing capabilities, and the integration of this mobile node on the intelligent transportation system to gather data in WSN contexts is becoming more and more popular as these vehicles proliferate. Although these mobile devices might enhance network performance, however it is difficult to design a suitable transportation path with the limited energy resources with network connectivity. To solve this problem, we have proposed a novel itinerary planning schema data gatherer (IPS-DG) model. Furthermore, we use the path planning module (PPM) which finds the transportation path to travel the shortest distance. We have compared our results under different aspect such as life span, energy consumption, and path length with Low Energy Adaptive Clustering Hierarchy (LEACH), Multi-Hop Weighted Revenue (MWR), Single-Hop Data Gathering Procedure (SHDGP).

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

----------------------------------------------------------ABSTRACT-----------------------------------------------------------
The problem of data collection in wireless sensor networks has been well studied in different schemes according
to many factors like energy, latency, and throughput. Most of the methods suffer with the problem of energy
depletion which affects the lifetime of the overall network. To solve the problem of energy depletion and routing
problems, an time orient delay tolerant density estimation technique has been proposed which uses energy
depletion based routing to perform data collection in wireless sensor networks. The sink node identifies the set
of sensor data nodes at each region and estimates the density of sensor sink nodes using the current status of the
network and performs the data approximation which specifies the amount of data present in the sensor data
node. The data estimation technique is performed at each time interval and the sensor sink node decides the
process of data collection based on the density estimation. Similarly the method chooses a route to collect the
data using energy depletion routing (EDR). The proposed method collects the sensor data in most efficient
manner and reduces the latency and time complexity. Also the proposed method improves the overall lifetime of
the network.

I. INTRODUCTION:
The wireless sensor networks, which has movable sensor nodes, unmovable sinks and un movable data
sensor with dynamic topology could be deployed at any location independent of location. The sensor nodes
stores various information’s about different concepts of any category. The modern world network stores various
information’s at different geographic locations which can be retrieved at later time using wireless protocols. The
amount of information grows with day to day basis and need more sophisticated organized storage and
representation scheme so that it could be referred and accessed easily. To provide such an access support and
lookup , there are many approaches available in the literature but the association rule which shows the more
exact information about the data locality.
The information in wireless sensor network is stored in different sensor nodes of the network and
extracted at the time whenever required. In earlier approaches the sensor nodes are monitored or update the sink
at periodic manner and it is not trustable that the sensor node updates the original information. Sometimes few
nodes may provide fake information to get priority than other nodes which must be avoided. The agent system
which supports movement of agents , where the system can generate N number of agents which can be moved
between locations or sensor nodes. The agent can perform specified task whenever necessary and generate or
update the rules generated.
The density measure shows the number of sensor data nodes present in any geographic region of the
network. The density measure can be computed based on the number of mobile nodes present in the region and
the number of sensor data nodes present. By computing the density measure we can infer the amount of recent
data available at each sink can be estimated. The time orient delay tolerant density estimation is the process of
computing the density of data available at any specific region and the amount of delay could incur in collecting
the data. By computing this measure, the data collection can be measured for its effectiveness which overrides
the problem of unnecessary energy depletion of all the nodes involve in data collection.

The EDR-Energy depletion routing is the process of identifying a single route from large set of
available routes. For each route available, the energy depletion could occur by collecting the data can be
estimated and a least depletion route can be selected which improves the lifetime of the network and increases
the efficiency of data collection.
II. RELATED WORKS:
There are many approaches has been discussed in the literature for the data collection in wireless sensor
networks and we discuss few of them here in this section.
An Efficient Data Aggregation Scheme in Wireless Sensor Networks [1], proposed an automatic time
series modeling based data aggregation scheme in wireless sensor networks. The main idea behind this scheme
is to decrease the number of transmitted data values between sensor nodes and aggregator by using time series
prediction model. Its can effectively save the precious battery energy of wireless sensor node while keeping the
predicted data values of aggregator within application defined error threshold. We show through experiments
with real data that the predicted values of our proposed scheme fit the real sensed values very well and fewer
messages are transmitted between sensor node and aggregator.
A Graph-Center-Based Scheme for Energy-Efficient Data Collection in Wireless Sensor Networks [3],
propose a data collection scheme for the WSN, based on the concept of the center of the graph in graph theory.
The purpose of the scheme is to use less power in the process of data collection. Because it is mostly true that
the sensors of WSN are powered by batteries, power saving is an especially important issue in WSN. In this
paper, we will propose the energy-saving scheme, and provide the experimental results. It is shown that under
the energy consumption model used in the paper, thescheme saves about 20% of the power collecting data from
sensors.
Approximate Self-Adaptive Data Collection in Wireless Sensor Networks [4], propose an Approximate
Self-Adaptive data collection technique (ASA), to approximately collect data in a distributed wireless sensor
network. ASA investigates the spatial correlations between sensors to provide an energy-efficient and balanced
route to the sink, while each sensor does not know any global knowledge on the network. Based on our synthetic
experiences, we demonstrate that ASA can provide significant communication (and hence energy) savings and
equal energy consumption of the sensor nodes.
A Feedback-Based Secure Path Approach for Wireless Sensor Networks Data Collection [8], propose
to use a novel tracing-feedback mechanism, which makes full use of the routing functionality of WSN, to
improve the quality of data collection. The algorithms of the approach are easy to be implemented and
performed in WSN. We also evaluate the approach with a simulation experiment and analyze the simulation
results in detail. We illustrate that the approach is efficient to support secure data collection in wireless sensor
network.
Optimizing Data Collection for Object Tracking in Wireless Sensor Networks [9], proposed to
optimize an algorithm of object tracking in wireless sensor network (WSN). The task under consideration is to
control movement of a mobile sink, which has to reach a target in the shortest possible time. Utilization of the
WSN resources is optimized by transferring only selected data readings (target locations) to the mobile sink.
Simulations were performed to evaluate the proposed modifications against state-of-the-art methods. The
obtained results show that the presented tracking algorithm allows for substantial reduction of data collection
costs with no significant increase in the amount of time that it takes to catch the target.
Data collection is one of the main research topics of wireless sensor networks in recent years, and, data
collection research outside users through wireless sensor networks to collect perception data from the
monitoring area. Formal concept analysis is a data analysis tool, especially for investigation and treatment can
be given information to discover important information hidden in the data behind. The Design of Data
Collection Methods in Wireless Sensor Networks Based on Formal Concept Analysis [11], proposes the data
collection methods in Wireless Sensor Networks based on formal concept analysis. Experiments show that the
proposed FCA-based data collection algorithm in WSN more effective than the traditional algorithm.
Data Collection with Multiple Sinks in Wireless Sensor Networks [12], consider Multiple-Sink Data
Collection Problem in wireless sensor networks, where a large amount of data from sensor nodes need to be
transmitted to one of multiple sinks. We design an approximation algorithm to minimize the latency of data
collection schedule and show that it gives a constant-factor performance guarantee. We also present a heuristic
algorithm based on breadth first search for this problem. Using simulation, we evaluate the performance of these
two algorithms, and show that the approximation algorithm outperforms the heuristic up to 60%.
A Multi-objective Approach for Data Collection in Wireless Sensor Networks [13], addresses the
problem of data collection using mobile sinks in a WSN. We provide a framework that studies the trade-off
between energy consumption and delay of data collection. This framework provides solutions that allow
decision makers to optimally design the data collection plan in wireless sensor networks with mobile sinks.
All the above discussed approaches has the problem of energy depletion and latency which has to be
reduced to maximize the lifetime and energy of the sensor nodes.

3.1 Time Orient Density Estimation:
The time orient density estimation is performed at regular time interval. The method identifies the set
of data sensor nodes present in each region where the whole geographic region is split into number of small
regions. For each of the region being split, the method computes the number of data sensor presents and the
number of sensor nodes present in current time. The sink node maintains different details about the data
reception from each of the data sensor in the previous time window. Based on all these informations, the
method computes the possible data density to be stored in the data sensors at the current time window. The
computed density value will be used in the next stage of data collection.

Step4: stop.
3.2 Time Orient Delay Estimation:
The delay estimation is performed at each time interval by the sink node. As like the density
estimation, the method splits the geographic region into number of small parts and for each region the delay
incur will be estimated. From the network trace generated at the previous data collection, the method identifies
the set of routes has been used to perform data collection. The method computes the average hop count and
average delay incur in collecting the data using the data density score. Based on the both the measure computed
the process of data collection will be initiated by the sink node in the final stage.
Algorithm:
Input: Network Trace NT, Geographic Details GD.
Output: Delay Estimation Score DS.

Step2: split the geographic region into many small scale regions.

DS = AHP×ADL
End.
End

Step4: return DS.
Step5: stop.
3.3 Route Discovery:
The method discovers available routes according to the geographical status of the network. The
method employs popular AODV route discovery procedure to collect the available routes. The method generates
route discovery request by sending the route request packet which is performed on demand. And the sink will
wait for the route reply and when the reply s being received from the neighbor nodes then the sink arranges the
routes according to the hop count. The rearranged route set will be given to the EDR to perform route selection
and data collection.
3.4 Energy Depletion Routing:
The energy depletion based routing procedure compute energy depletion factor for each of route
discovered at the early stage. From the routes being identified, the method computes the energy depletion factor
using the time orient density estimation and time orient delay estimation factors. For each route being available,
the method computes the energy depletion measure which represents the possible energy loss could occur at the
intermediate sensor nodes. Based on the depletion measure a single route will be selected to perform data
collection.
Algorithm:
Input: Delay Estimation Score DS, Density Estimation Score DES, Route Set Rs
Output: Selected route SR.

Step2: for each route Ri from Rs

𝐶𝐷𝑒𝑙𝑎𝑦
×
𝐷𝑒𝑛𝑠𝑖𝑡𝑦
𝐶𝐷𝑒𝑛𝑠𝑖𝑡𝑦
× 𝑁𝐻) × µ
Here µ- the value of energy depletion incur in transmitting single byte stream.
End.
Step3: Choose the least depletion route.
Step 4: Perform data collection request through the route selected.
Step5: stop.
3.5 Data Collection:
At this stage, from the route selected at the previous EDR phase, the query will be transferred and the
intermediate sensors forward the request to reach the data sensor. the data sensor replies with the most recent
data available with it towards the sink. In this way, the data collection is performed at regular time interval also
if the estimated density value is less than the specific thresholds then the data collection for the time window
will be skipped but included in the next time slot to minimize the energy depletion occur by unnecessary data
collection.
IV. RESULTS AND DISCUSSION:
