TWO LEVEL DATA FUSION MODEL FOR DATA MINIMIZATION AND EVENT DETECTION IN PERI...pijans
Periodic Wireless Sensor Networks used for many applications such continuous Weather Monitoring, Cattle Monitoring, Water Quality Monitoring and Event Detection Applications. Due to continuous Monitoring, Large Amount of redundant data is transferred over the Network, which causes depletion of energy resources. Data Fusion is used with the Aim of deleting redundant, inconsistent data and provides more accurate data to the Sink. However, redundant data improves the data quality. Therefore, Two Level Data Fusion Model is proposed in this paper to transfer minimized data with the ability of accurately
determines the event with minimum Delay. Data Fusion Model employs Cluster based Data Fusion at Two Levels; First Level at Sensor Node ( SNs) and another level at Cluster Head ( CH )Node. At the first level of Fusion, SNs Send single most common measurement to the CH by using a similarity function. Second Level of Fusion is applied on CH to remove similar multi attribute measurement. Also at CH Node, Multiple Correlation is used to accurately distinguish the abnormal event from the normal event or outliers within minimum delay. Experimental results are performed on real data to validate proposed Data Fusion Model is Better in terms of data transfer over Network, Redundancy, Energy Consumption over the Prefix Filtering Technique (PFF) . This Model is also used to accurately detect early events in case of Emergency.

ALL ABOUT DATA AGGREGATION IN WIRELESS SENSOR NETWORKSEditor IJCTER
A wireless sensor network is a computer network that consists of small devices called
sensor nodes. These sensor nodes have the ability to sense different environmental conditions like
temperature, pressure, etc. All these sensor nodes send their data to a central node or base station.
This creates a large communication overhead the energy source for these nodes is usually a battery.
This gives rise to huge consumption of energy and resources. So a solution is required that
overcomes the above problems. Data aggregation is one of its solutions. This method consists of
aggregators that combine the data coming from the sensor nodes and then passes it to the base
station. With the help of data aggregation we reduce the energy consumption by eliminating
redundancy and we can enhance the life time of wireless network. The purpose of the proposed paper
is to explain data aggregation in wireless sensor network, how it works, different techniques of data
aggregation and the comparison among them.

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

A Reliable Routing Technique for Wireless Sensor NetworksEditor IJCATR
Wireless Sensor Network (WSN) consists of very large number of sensor nodes which are deployed close to the area which
is to be monitored so as to sense various environmental conditions. WSN is a data-driven network which produces large amount of data
and also sensor nodes are energy-limited devices and their energy consumption is mainly associated with data routing. Therefore it is
necessary to perform redundant data aggregation so as to save energy. In this work data aggregation is achieved with the help of two key
approaches namely Clustering approach and In-network data aggregation. These two approaches help to save energy and thereby
increasing the lifetime of the network. The proposed work has some key features like reliable cluster formation, high data aggregation
rate, priority of packets, minimized overhead, multiple routes, reduced energy consumption which enhance the network lifetime. The
performance evaluation of the proposed approach is carried out using Network Simulator- version 2

Rapid and Energy Efficient Data Transmission Technique using Event Aggregatio...ijsrd.com
In this Paper we analyze WSNs and show that it's possible to achieve better performances in terms of energy consumption and latency. Event aggregation in WSNs is a process of combining several low-level events into a high-level event to eliminate redundant information to be transmitted and thus save energy. Existing works on event aggregation consider either latency constraint or aggregation function, but not both. Moreover, existing works only consider optimal aggregation for single high level event, but many applications are composed of multiple high-level events. This paper studies the problem of aggregating multiple high-level events in WSNs with different latency constraints and aggregation functions. We propose relation matrix to define aggregation function, which describes the similarity among limited number of primitive events rather than the growing number of high-level events. Based on it, we propose an event aggregation algorithm jointly considering the two issues for single high-level event. This algorithm supports partial aggregation which is more general than fully aggregation. Through selection the optimal base events, the work is extended to multiple high level events and consider the practical reliable constraint. The simulation results show that our algorithm outperforms existing approaches and saves significant amount of energy (up to 35% in our system).

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

CONSENSUS BASED DATA AGGREGATION FOR ENERGY CONSERVATION IN WIRELESS SENSOR N...ijdpsjournal
Our planet is abundant with raw data and to monitor the available data properly, processing of the enormous raw data is very vital. One of the key things in development of mankind and the nature is to acquire as much data as possible and to react appropriately in accordance with the studied data. It’s nothing but diagnosis of the physical world by studying the data acquired from them in order to take proper measures that can help in treating them better. Large volume of data incurs high energy consumption for its transmission and thus results in decrease of overall network lifetime.
Wireless Sensor Network (WSN) is a collection of multiple sensor nodes that all together forms a network for transmitting data acquired by each sensor node to sink known as Base Station (BS). In hierarchical routing acquired data are sent via relay agents like Cluster Heads (CH). The Cluster Heads must be customised with computations and formulations, which will help in aggregating the gathered data, in order to reduce energy consumption while transmitting the data further in the network while maintaining the data integrity to withhold the significance of every single value in a data set.
Design Issues and Applications of Wireless Sensor Networkijtsrd
Efficient design and implementation of wireless sensor networks has become a hot area of research in recent years, due to the vast potential of sensor networks to enable applications that connect the physical world to the virtual world. By networking large numbers of tiny sensor nodes, it is possible to obtain data about physical phenomena that was difficult or impossible to obtain in more conventional ways. In future as advances in micro-fabrication technology allow the cost of manufacturing sensor nodes to continue to drop, increasing deployments of wireless sensor networks are expected, with the networks eventually growing to large numbers of nodes.Potential applications for such large-scale wireless sensor networks exist in a variety of fields, including medical monitoring, environmental monitoring, surveillance, home security, military operations, and industrial machine monitoring etc. G.

Scalable and Robust Hierarchical Group of Data in Wireless Sensor NetworksIJERA Editor
In many sensor applications, the data collected from individual nodes is aggregated at a base station or host computer. To reduce energy consumption, many systems also perform in-network aggregation of sensor data at intermediate nodes enrooted to the base station. Most existing aggregation algorithms and systems do not include any provisions for security, and consequently these systems are vulnerable to a wide variety of attacks. In particular, compromised nodes can be used to inject false data that leads to incorrect aggregates being computed at the base station. We discuss the security vulnerabilities of data aggregation systems, and present a survey of robust and secure aggregation protocols that are resilient to false data injection attacks. The Proposed SHIA Algorithm builds on the Secure Hierarchical In-Network Aggregation, in order to achieve not only secure but also efficient WSN data collection over a series of aggregations.

Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

2. Information based sensor
tasking
Information-Based Sensor Tasking (IBST) is a
smart way for sensors in a network to decide when
and what to sense. Instead of just sensing all the
time, sensors use IBST to focus on what's most
important. It helps them save energy and work
together better to gather the right information at
the right time.
3. Importance of routing information
aggregation
Reduced Energy Consumption
Improved Network Efficiency
Minimized Latency
Reduced Data Redundancy
Increased Network Lifetime
4. Sensor tasking
Sensor tasking is the process of assigning
specific sensing tasks to individual
sensors in a sensor network. These tasks
are such as temperature, humidity, light,
or specific events.
Sensor tasking involves determining when
and where sensors should perform these
tasks to optimize resource usage and
achieve the desired monitoring objectives.
5. Data aggregation and its
importance in WSN
Data aggregation is a process of
combining and summarizing data from
multiple sensor nodes into a smaller set of
meaningful information.
Importance:
◦ Reduced Energy Consumption
◦ Bandwidth Conservation
◦ Lower Latency
6. Temporal data
Temporal data refers to data that is
associated with a specific time or time
range. It includes any information that
has a time component, such as
timestamps, dates, durations, or
sequences of events.
7. IDSQ (Information-Driven Sensor
Querying)
Information-Driven Sensor Querying
(IDSQ) is a technique used to efficiently
gather information from sensor nodes in
response to specific queries or requests.
This reduces unnecessary data
transmission and processing, leading to
energy savings and increased network
efficiency.
8. Geographic hash table (GHT)
The Geographic Hash Table (GHT) is a data
storage and retrieval mechanism used in
sensor networks. It associates data with
geographic coordinates, allowing nodes in the
network to store and retrieve data based on
their physical location.
GHT uses a hash function to map data to
specific geographic regions, ensuring that
data is stored at nodes closest to its
corresponding coordinates. This approach
helps reduce network traffic and improves
data access efficiency in sensor networks.
9. In-network aggregation
In-network aggregation is a technique
used to reduce the amount of data that
needs to be transmitted to a central
location or sink node. Instead of each
sensor node sending its raw data directly
to the sink, nodes can aggregate or
combine their data locally before
transmitting it.
10. Data centric storage in WSN
Data centric storage (DCS) is a method
proposed to support queries from any
node in the network by providing a
rendezvous mechanism for data and
queries that avoids flooding the entire
network.
Each event is stored in a sensor node,
which is the owner of the event. If a
query is intended for an event, it is
directed to that sensor node.
