Cooperative load balancing and dynamic channel allocation for cluster based m...LogicMindtech Nologies
This document discusses a proposed mechanism for cooperative load balancing and dynamic channel allocation in cluster-based mobile ad hoc networks. The mechanism aims to improve bandwidth efficiency and performance for non-uniform traffic loads. It utilizes clustering, dynamic channel allocation, and cooperative load balancing to reduce energy consumption, increase throughput, and decrease inter-packet delay variation. Extensive simulations showed the proposed approach improves bandwidth efficiency compared to protocols without these mechanisms, as well as compared to IEEE 802.15.4 and 802.11 protocols.
Control Channel Dilemma (CCD) is still an open problem for Cognitive Radio Network (CRN). In this
article, we investigate and present a novel solution of Distributed Coordination in CRN to mitigate the
necessity for a common control channel. This scheme is based on the fact that a group of nearby nodes
almost detects the same frequency spectrum. That will allow every group of close nodes to choose a node
called coordinator, which in its turn chooses a reliable control channel for the group, then the reaming
nodes become slaves. Furthermore, the nodes that belong to two or more groups have an important role in
maintaining the network connectivity since they act as bridges to relay data between different groups. The
proposed approach carries potentials to provide robust operation under network dynamics conditions.
Finally, several simulation experiments are presented to validate the proposed approach.

GPSFR: GPS-Free Routing Protocol for Vehicular Networks with Directional Ante...ijwmn
Efficient and practical communications between large numbers of vehicles are critical in providing high level of safety and convenience to drivers. Crucial real-time information on road hazard, traffic conditions and driver services must be communicated to vehicles rapidly even in adverse environments, such as “urban canyons” and tunnels. We propose a novel routing protocol in vehicular networks that does not require position information (e.g. from GPS) but instead rely on relative position that can be determined dynamically. This GPS-Free Geographic Routing (GPSFR) protocol uses the estimated relative position of vehicles and greedily chooses the best next hop neighbor based on a Balance Advance (BADV) metric which balances between proximity and link stability in order to improve routing performance. In this paper, we focuses primarily on the complexity of routing in highways and solves routing problems that arise when vehicles are near interchanges, curves, and merge or exit lanes of highways. Our simulation results show that by taking relative velocity into account, GPSFR reduces link breakage to only 27% that of GPSR in the dense network. Consequently, GPSFR outperforms GPSR in terms of higher data delivery ratio, lower delay, less sensitivity of the network density and route paths’length
This document summarizes a research paper that proposes an Energy Efficient Reserved Path Routing Topology (RPRT) routing scheme for mobile ad hoc networks. The RPRT aims to improve energy efficiency and reduce end-to-end delay compared to the existing M-Trace routing scheme. It allows nodes to use estimated energy levels to make better channel admission control decisions for providing quality of service guarantees. The paper presents the RPRT scheme and its energy level estimation, routing discovery, route maintenance, and path selection mechanisms. Simulation results demonstrate that the RPRT achieves a 16% increase in energy efficiency and 37% reduction in end-to-end delay compared to M-Trace.

PERFORMANCE ANALYSIS OF WIRELESS MESH NETWORK USING ADAPTIVE INFORMANT FACTOR...IJCSES Journal
Wireless mesh network (WMN) has become an important leading technology which provides several types of useful applications such as community network, broadband home network and internet access, etc. The rise in the size of users in WMN has created a degradation of efficiency in a network especially in dense areas due to the clumsy channel allocation and hence creating many challenges for enhancing the users experience, network quality and throughput. Therefore in this paper, we proposed OCA based AIF model that can access the channel information and then it process to improve the RF channel association. The proposed OCA-AIF will function for each period when some interference is detected via AIF and we further extend this analysis by taking in to consideration the influence of interference to provide a high quality indicator in network. The analysis of result shows the optimization by our proposed approach which increases as per the increment of relay nodes (RNs).

system, which is In this paper, we proposed a novel efficient method of analyzing the ergodic channel
capacity of the cooperative amplify-and-forward (CAF) relay system. This is accomplished by employing a
very tight approximate moment applicable to myriad of fading environments including mixed and
composite fading channels. Three distinct adaptive source transmission policies were considered in our
analysis namely: (i) constant power with optimal rate adaptation (ORA); (ii) optimal joint power and rate
adaptation (OPRA); and (iii) fixed rate with truncated channel inversion (TCIFR). The proposed frame
work based on the novel approximate MGF method is sufficiently general to encapsulate all types of fading
environments (especially for the analysis of the mixed fading case)and provides significant advantage to
model wireless system for mixed and composite fading channel. In addition to simplifying computation
complexity of ergodic capacity for CAF relaying schemes treated in literature, we also derive closed form
expressions for the above three adaptive source transmission policies under Nakagami-m fading with i.n.d
statistics. The accuracy of our proposed method has been validated with existing MGF expressions that are
readily available for specific fading environments in terms of bounds, and via Monte Carlo simulations.

SECTOR TREE-BASED CLUSTERING FOR ENERGY EFFICIENT ROUTING PROTOCOL IN HETEROG...IJCNCJournal
The document proposes a new routing protocol called Sector Tree-Based Clustering for Energy Efficient Routing Protocol (STB-EE) for wireless sensor networks. STB-EE partitions the sensor field into dynamic sectors to balance the number of nodes per cluster. Within each sector, STB-EE constructs a minimum spanning tree to connect nodes and reduce long-distance communication. STB-EE selects cluster heads based on remaining energy and distance to the base station. Simulation results show STB-EE can improve network lifespan by about 15-16% compared to other protocols.
Energy Aware Routing Protocol for Energy Constrained Mobile Ad-hoc Networks IJECEIAES
Dynamic topology change and decentralized makes routing a challenging task in mobile ad hoc network. Energy efficient routing is the most challenging task in MANET due to limited energy of mobile nodes. Limited power of batteries typically use in MANET, and this is not easy to change or replace while running communication. Network disorder can occur for many factors but in middle of these factors deficiency of energy is the most significant one for causing broken links and early partition of the network. Evenly distribution of power between nodes could enhance the lifetime of the network, which leads to improving overall network transmission and minimizes the connection request. To discourse this issue, we propose an Energy Aware Routing Protocol (EARP) which considers node energy in route searching process and chooses nodes with higher energy levels. The EARP aim is to establish t he shortest route from source to destination that contains energy efficient nodes. The performance of EARP is evaluated in terms of packet delivery ratio, network lifetime, end-to-end delay and throughput. Results of simulation done by using NS2 network simulator shows that EARP can achieve both high throughput and delivery ratio, whereas increase network lifetime and decreases end-to-end delay.
Minimization of Energy Consumption using EPAR-DSR Protocol in ManetIRJET Journal
This document summarizes a research paper that proposes a new routing protocol called EPAR-DSR for minimizing energy consumption in mobile ad hoc networks (MANETs). The key points are:
1. EPAR-DSR aims to reduce energy consumption during packet transmission between nodes to extend the lifetime of battery-powered nodes in the MANET.
2. It modifies the Dynamic Source Routing (DSR) protocol to select routes based on the remaining energy of nodes as well as path length. This helps avoid overusing nodes with low battery levels.
3. Simulation results show that EPAR-DSR achieves higher throughput, longer network lifetime, and better packet delivery ratios compared to standard DSR
JOINT-DESIGN OF LINK-ADAPTIVE MODULATION AND CODING WITH ADAPTIVE ARQ FOR COO...IJCNCJournal
This paper analyzes the efficiency of a joint-design of an adaptive modulation and coding (AMC) at the
physical (PHY) layer with an adaptive Rmax-truncated selective-repeat automatic repeat request (ARQ)
protocol at the medium access control (MAC) layer to maximize the throughput of cooperative nonregenerative
relay networks under prescribed delay and/or error performance constraints. Particularly, we
generalize the existing design model/results for cross-layer combining of AMC along with truncated ARQ
in non-cooperative diversity networks in three-folds: (i) extension of the cross-layer PHY/MAC design or
optimization to cooperative diversity systems; (ii) generalization/unification of analytical expressions for
various network performance metrics to generalized block fading channels with independent but nonidentically
distributed (i.n.d) fading statistics among the spatially distributed nodes; (iii) analysis of the
effectiveness of joint-adaptation of the maximum retransmission limit Rmax of ARQ protocol and
cooperative diversity order N for delay-insensitive applications. Our insightful numerical results reveal
that the average throughput can be increased significantly by judiciously combining two additional degrees
of freedom (N and Rmax) that are available in cooperative amplify-and-forward (CAF) relay networks
besides employing AMC at the PHY layer, especially in the most challenging low signal-to-noise ratio
(SNR) regime.
A MIN-MAX SCHEDULING LOAD BALANCED APPROACH TO ENHANCE ENERGY EFFICIENCY AND ...IJCNCJournal
Energy efficiency and traffic management in Mobile Ad hoc Networks (MANETs) is a complex process due
to the self-organizing nature of the nodes. Quality of service (QoS) of the network is achieved by
addressing the issues concerned with load handling and energy conservation. This manuscript proposes a
min-max scheduling (M2S) algorithm for energy efficiency and load balancing (LB) in MANETs. The
algorithm operates in two phases: neighbor selection and load balancing. In state selection, the
transmission of the node is altered based on its energy and packet delivery factor. In the load balancing
phase, the selected nodes are induced by queuing and scheduling the process to improve the rate of load
dissemination. The different processes are intended to improve the packet delivery factor (PDF) by
selecting appropriate node transmission states. The transmission states of the nodes are classified through
periodic remaining energy update; the queuing and scheduling process is dynamically adjusted with energy
consideration. A weight-based normalized function eases neighbor selection by determining the most
precise neighbor that satisfies transmission and energy constraints. The results of the proposed M2SLB
(Min-Max Scheduling Load Balancing) proves the consistency of the proposed algorithm by improving the
network throughput, packet delivery ratio and minimizing delay and packet loss by retaining higher
remaining energy.
This document proposes an Enhanced and Integrated Ant Colony-Artificial Bee Colony (EIAC-ABCMR) approach for multicast routing in Vehicular Ad Hoc Networks (VANETs) that satisfies quality of service (QoS) constraints. EIAC-ABCMR determines an optimal multicast tree using a metaheuristic algorithm that integrates ant colony optimization and artificial bee colony algorithms. This prevents stagnation and delayed convergence issues. The algorithm formulates the multicast routing problem as a multi-objective function minimizing delay, cost, jitter while maximizing bandwidth. Simulation results show EIAC-ABCMR outperforms other multicast routing techniques in reducing multicast groups
A Cross Layer Based Scalable Channel Slot Re-Utilization Technique for Wirele...csandit
Due to tremendous growth of the wireless based application services are increasing the demand
for wireless communication techniques that use bandwidth more effectively. Channel slot reutilization
in multi-radio wireless mesh networks is a very challenging problem. WMNs have
been adopted as back haul to connect various networks such as Wi-Fi (802.11), WI-MAX
(802.16e) etc. to the internet. The slot re-utilization technique proposed so far suffer due to high
collision due to improper channel slot usage approximation error. To overcome this here the
author propose the cross layer optimization technique by designing a device classification
based channel slot re-utilization routing strategy which considers the channel slot and node
information from various layers and use some of these parameters to approximate the risk
involve in channel slot re-utilization in order to improve the QoS of the network. The simulation
and analytical results show the effectiveness of our proposed approach in term of channel slot
re-utilization efficiency and thus helps in reducing latency for data transmission and reduce
channel slot collision.
Energy Behavior in Ad Hoc Network Minimizing the Number of Hops and Maintaini...CSCJournals
Wireless ad-hoc mesh network is a special kind of network, where all of the nodes move in time. The topology of the network changes as the nodes are in the proximity of each other. Ad-hoc networks are generally self-configuring no stable infrastructure takes a place. In this network, each node should help relaying packets of neighboring nodes using multi-hop routing mechanism. This mechanism is needed to reach far destination nodes to solve problem of dead communication. This multiple traffic "hops" within a wireless mesh network caused dilemma. Wireless mesh network that contain multiple hops become increasingly vulnerable to problems such as energy degradation and rapid increasing of overhead packets. This paper provides a generic routing framework that balances energy efficient broadcast schemes in Wireless (Ad-Hoc) Mesh Network and maintaining connectivity of nodes (mobile terminals). Typically, each node’s activities will consume energy, either for sending packets, receiving or preparing/processing packets. Number of hops, distance of nodes, and size of packet will determine the consumption of energy. The framework is based on the principle that additional relay nodes with appropriate energy and routing metric between source and final destination significantly reduces the energy consumption necessary to deliver packets in Wireless (Ad-Hoc) Mesh Network while keep the connectivity of dynamic nodes. Using the framework, the average network connectivity is kept 18% higher and the lifetime of network lasting more than 2.38% compared with network with Link State Routing mechanism. The simulation notes that the end-to-end delay may increase rapidly if relay nodes are more than five.
Performance evaluation of interference aware topology power and flow control ...IJECEIAES
Multi-Radio Multi-Channel Wireless Mesh Network (MRMC-WMN) has been considered as one of the key technology for the enhancement of network performance. It is used in a number of real-time applications such as disaster management system, transportation system and health care system. MRMC-WMN is a multi-hop network and allows simultaneous data transfer by using multiple radio interfaces. All the radio interfaces are typically assigned with different channels to reduce the effect of co-channel interference. In MRMC-WMN, when two nodes transmit at the same channel in the range of each other, generates co-channel interference and degrades the network throughput. Co-channel interference badly affects the capacity of each link that reduces the overall network performance. Thus, the important task of channel assignment algorithm is to reduce the co-channel interference and enhance the network performance. In this paper, the problem of channel assignment has been addressed for MRMC-WMN. We have proposed an Interference Aware, Topology, Power and Flow Control (ITPFC) Channel Assignment algorithm for MRMC-WMN. This algorithm assignes the suitable channels to nodes, which provides better link capacity and reduces the co-channel interference. In the previous work performance of the proposed algorithm has been evaluated for a network of 30 nodes. The aim of this paper is to further evaluate the performance of proposed channel assignment algorithm for 40 and 50 nodes network. The results obtained from these networks show the consistent performance in terms of throughput, delay, packet loss and number of channels used per node as compared to LACA, FCPRA and IATC Channel Assignment algorithms.
This paper evaluates the performance of an Optimized Cross-Layers Protocol (OXLP) for wireless sensor networks through simulation. The OXLP integrates MAC and network layer functionality to improve energy efficiency. It organizes nodes into clusters, determines routing paths from nodes to cluster heads to the base station, and creates a transmission schedule to avoid collisions. The simulation compares the OXLP to other cross-layer and routing protocols based on packet delivery ratio, network lifetime, delivery delay, and energy consumption under varying traffic loads. The results show the OXLP achieves good performance for these metrics and scales well to larger network sizes.
Route Stability in Mobile Ad-Hoc Networksarpublication
A Mobile Ad Hoc Network (MANET) is a wireless network consisting of mobile nodes, which can communicate with each other without any infrastructure support. In these networks, nodes typically cooperate with each other, by forwarding packets for nodes which are not in the communication range of the source node. A fundamental issue arising in mobile ad-hoc networks (MANETs) is the selection of the optimal path between any two nodes. A method that has been advocated to improve routing efficiency is to select the most stable path so as to reduce the latency and the overhead due to route reconstruction. In this work we study the stability of a routing path, which is subject to link failures caused by node mobility, and we consider as metrics of interest the duration and the availability of a path. Moreover, using the results on path duration and availability, we show how to determine the optimal path in terms of route stability, under the Random Direction mobility models.

A Cluster Is Only As Strong As its Weakest Link DataWorks Summit
Early detection and correction of cluster health issues is a vital part of daily cluster management, no matter the size. Building and managing a healthy cluster is the best cure for meeting service level agreements and preventing or avoiding elongated troubleshooting. A cluster is effective and efficient when problems are detected and eliminated early. Fortunately, deploying simple tools and processes prevents minor problems from becoming major headaches. This talk covers how we developed, tested, and deployed a comprehensive health process based on real life events and experiences. The table driven health check runs a full scan in ~2 seconds and includes: a checklist, ‘positive’ error pattern matching, enabling and disabling node blacklisting, logging, validating file systems, processing very large log files, trapping in-rack network faults (adds 5 seconds to accurately detect packet loss), and recommissioning nodes into production.

transmission of the node is altered based on its energy and packet delivery factor. In the load balancing
phase, the selected nodes are induced by queuing and scheduling the process to improve the rate of load
dissemination. The different processes are intended to improve the packet delivery factor (PDF) by
selecting appropriate node transmission states. The transmission states of the nodes are classified through
periodic remaining energy update; the queuing and scheduling process is dynamically adjusted with energy
consideration. A weight-based normalized function eases neighbor selection by determining the most
precise neighbor that satisfies transmission and energy constraints. The results of the proposed M2SLB
(Min-Max Scheduling Load Balancing) proves the consistency of the proposed algorithm by improving the
network throughput, packet delivery ratio and minimizing delay and packet loss by retaining higher
remaining energy.
This document proposes an Enhanced and Integrated Ant Colony-Artificial Bee Colony (EIAC-ABCMR) approach for multicast routing in Vehicular Ad Hoc Networks (VANETs) that satisfies quality of service (QoS) constraints. EIAC-ABCMR determines an optimal multicast tree using a metaheuristic algorithm that integrates ant colony optimization and artificial bee colony algorithms. This prevents stagnation and delayed convergence issues. The algorithm formulates the multicast routing problem as a multi-objective function minimizing delay, cost, jitter while maximizing bandwidth. Simulation results show EIAC-ABCMR outperforms other multicast routing techniques in reducing multicast groups
A Cross Layer Based Scalable Channel Slot Re-Utilization Technique for Wirele...csandit
Due to tremendous growth of the wireless based application services are increasing the demand
for wireless communication techniques that use bandwidth more effectively. Channel slot reutilization
in multi-radio wireless mesh networks is a very challenging problem. WMNs have
been adopted as back haul to connect various networks such as Wi-Fi (802.11), WI-MAX
(802.16e) etc. to the internet. The slot re-utilization technique proposed so far suffer due to high
collision due to improper channel slot usage approximation error. To overcome this here the
author propose the cross layer optimization technique by designing a device classification
based channel slot re-utilization routing strategy which considers the channel slot and node
information from various layers and use some of these parameters to approximate the risk
involve in channel slot re-utilization in order to improve the QoS of the network. The simulation
and analytical results show the effectiveness of our proposed approach in term of channel slot
re-utilization efficiency and thus helps in reducing latency for data transmission and reduce
channel slot collision.
Energy Behavior in Ad Hoc Network Minimizing the Number of Hops and Maintaini...CSCJournals
Wireless ad-hoc mesh network is a special kind of network, where all of the nodes move in time. The topology of the network changes as the nodes are in the proximity of each other. Ad-hoc networks are generally self-configuring no stable infrastructure takes a place. In this network, each node should help relaying packets of neighboring nodes using multi-hop routing mechanism. This mechanism is needed to reach far destination nodes to solve problem of dead communication. This multiple traffic "hops" within a wireless mesh network caused dilemma. Wireless mesh network that contain multiple hops become increasingly vulnerable to problems such as energy degradation and rapid increasing of overhead packets. This paper provides a generic routing framework that balances energy efficient broadcast schemes in Wireless (Ad-Hoc) Mesh Network and maintaining connectivity of nodes (mobile terminals). Typically, each node’s activities will consume energy, either for sending packets, receiving or preparing/processing packets. Number of hops, distance of nodes, and size of packet will determine the consumption of energy. The framework is based on the principle that additional relay nodes with appropriate energy and routing metric between source and final destination significantly reduces the energy consumption necessary to deliver packets in Wireless (Ad-Hoc) Mesh Network while keep the connectivity of dynamic nodes. Using the framework, the average network connectivity is kept 18% higher and the lifetime of network lasting more than 2.38% compared with network with Link State Routing mechanism. The simulation notes that the end-to-end delay may increase rapidly if relay nodes are more than five.
Performance evaluation of interference aware topology power and flow control ...IJECEIAES
Multi-Radio Multi-Channel Wireless Mesh Network (MRMC-WMN) has been considered as one of the key technology for the enhancement of network performance. It is used in a number of real-time applications such as disaster management system, transportation system and health care system. MRMC-WMN is a multi-hop network and allows simultaneous data transfer by using multiple radio interfaces. All the radio interfaces are typically assigned with different channels to reduce the effect of co-channel interference. In MRMC-WMN, when two nodes transmit at the same channel in the range of each other, generates co-channel interference and degrades the network throughput. Co-channel interference badly affects the capacity of each link that reduces the overall network performance. Thus, the important task of channel assignment algorithm is to reduce the co-channel interference and enhance the network performance. In this paper, the problem of channel assignment has been addressed for MRMC-WMN. We have proposed an Interference Aware, Topology, Power and Flow Control (ITPFC) Channel Assignment algorithm for MRMC-WMN. This algorithm assignes the suitable channels to nodes, which provides better link capacity and reduces the co-channel interference. In the previous work performance of the proposed algorithm has been evaluated for a network of 30 nodes. The aim of this paper is to further evaluate the performance of proposed channel assignment algorithm for 40 and 50 nodes network. The results obtained from these networks show the consistent performance in terms of throughput, delay, packet loss and number of channels used per node as compared to LACA, FCPRA and IATC Channel Assignment algorithms.
This paper evaluates the performance of an Optimized Cross-Layers Protocol (OXLP) for wireless sensor networks through simulation. The OXLP integrates MAC and network layer functionality to improve energy efficiency. It organizes nodes into clusters, determines routing paths from nodes to cluster heads to the base station, and creates a transmission schedule to avoid collisions. The simulation compares the OXLP to other cross-layer and routing protocols based on packet delivery ratio, network lifetime, delivery delay, and energy consumption under varying traffic loads. The results show the OXLP achieves good performance for these metrics and scales well to larger network sizes.
Route Stability in Mobile Ad-Hoc Networksarpublication
A Mobile Ad Hoc Network (MANET) is a wireless network consisting of mobile nodes, which can communicate with each other without any infrastructure support. In these networks, nodes typically cooperate with each other, by forwarding packets for nodes which are not in the communication range of the source node. A fundamental issue arising in mobile ad-hoc networks (MANETs) is the selection of the optimal path between any two nodes. A method that has been advocated to improve routing efficiency is to select the most stable path so as to reduce the latency and the overhead due to route reconstruction. In this work we study the stability of a routing path, which is subject to link failures caused by node mobility, and we consider as metrics of interest the duration and the availability of a path. Moreover, using the results on path duration and availability, we show how to determine the optimal path in terms of route stability, under the Random Direction mobility models.

A Cluster Is Only As Strong As its Weakest Link DataWorks Summit
Early detection and correction of cluster health issues is a vital part of daily cluster management, no matter the size. Building and managing a healthy cluster is the best cure for meeting service level agreements and preventing or avoiding elongated troubleshooting. A cluster is effective and efficient when problems are detected and eliminated early. Fortunately, deploying simple tools and processes prevents minor problems from becoming major headaches. This talk covers how we developed, tested, and deployed a comprehensive health process based on real life events and experiences. The table driven health check runs a full scan in ~2 seconds and includes: a checklist, ‘positive’ error pattern matching, enabling and disabling node blacklisting, logging, validating file systems, processing very large log files, trapping in-rack network faults (adds 5 seconds to accurately detect packet loss), and recommissioning nodes into production.

A presentation on behalf of the Pakistan Early Recovery Cluster Working Group at the Pakistan 2010 Inter-Agency Humanitarian Appeal Process Workshop, September 14-15, 2009, Islamabad, Pakistan.
The document compares the performance of the Dynamic Source Routing (DSR) protocol and Cluster Based Routing Protocol (CBRP) in mobile ad hoc networks. It simulates the two protocols under varying conditions of node density, mobility, and network traffic. The results show that CBRP generally has better packet delivery, channel utilization, delay, routing load, and control overhead, especially in denser networks with higher traffic and mobility levels, indicating it is more scalable for large ad hoc networks.
This document summarizes the agenda and discussion from the Cluster 3 meeting on May 7th, 2014. The key topics discussed were:
- The terms of reference and links between Clusters 1, 2, and 3 in developing a framework for valuing spectrum.
- An overview of existing studies and reports on valuing the social and economic impacts of spectrum use. Examples discussed included Cave reports, BEREC/RSPG reports, and an LSE seminar.
- A proposed work plan for Cluster 3, including collating existing study data, providing input to the government's Expert Panel, and potentially conducting further studies on approaches for valuing spectrum.
- An update on the UK Spectrum Strategy
The document summarizes the Cluster Based Routing Protocol (CBRP) for mobile ad hoc networks. CBRP divides the network into clusters with cluster heads that maintain routing information and perform routing functions. Key aspects of CBRP include periodic hello messages to track neighbors, identifier-based clustering, on-demand route discovery using cluster heads, source routing with loose and strict routes, local route repair instead of re-routing, and advantages like lower overhead and higher delivery rates compared to other protocols. CBRP is well-suited for situations requiring mobile network connectivity like disaster recovery or military operations.

The sensor nodes contain sensors, processors, memory, and radios. Wireless sensor networks can be either unstructured with dense node distribution or structured with few scattered nodes.
Call Admission Control (CAC) with Load Balancing Approach for the WLAN NetworksIJARIIT
The cell migrations take place between the different network operators, and require the significant information exchange between the operators to handle the migratory users. The new user registration requires the pre-shared information from the user’s equipment, which signifies the user recognition before registering the new user over the network. In this thesis, the proposed model has been aimed at the development of the new call admission control mechanism with the sub-channel assignment. The very basic utilization of the proposed model is to increase the number of the users over the given cell units, which is realized by using the sub-channel assignment to the users of the network. The proposed model is aimed at solving the issue by assigning the dual sub channels over the single communication channel. Also the proposed model is aimed at handling the minimum resource users by incorporating the load balancing approach over the given network segment. The load balancing approach shares the load of the overloaded cell with the cell with lowest resource utilization. The proposed model performance has been evaluated in the various scenarios and over all of the BTS nodes. The proposed model results have been obtained in the form of the resource utilization, network load, transmission delay, consumed bandwidth and data loss. The proposed model has shown the efficiency obtained by using the proposed call admission control (CAC) along with the new load balancing mechanism. The proposed model has shown the robustness of the proposed model in handling the cell overloading factors.

Modified PREQ in HWMP for Congestion Avoidance in Wireless Mesh NetworkIRJET Journal
This document summarizes a proposed technique called Modified PREQ in HWMP for Congestion Avoidance in Wireless Mesh Networks. The technique aims to determine congested paths using CCNF frames and provide rerouting to less congested paths before congestion occurs to reduce burden on congested nodes. It allows continued packet transmission on congested paths until a rerouting path is found during congestion scenarios. When a packet is transmitted on the new path, the previous path is deleted to avoid further delay. Sequence numbers are used to avoid flooding the network. The paper compares this Modified PREQ technique to other congestion avoidance techniques to improve throughput and average delay using an NS-3 simulator.
The document contains 14 abstracts from IEEE 2012 papers related to networks and network security, wireless networks, mobile computing, wireless sensor networks, and knowledge and data mining. The abstracts summarize research on topics such as load balancing in content delivery networks, authentication protocols for ad-hoc networks, privacy and integrity in sensor networks, opportunistic routing in wireless networks, throughput maximization in wireless networks, and prediction of user web browsing behavior using Markov models.
The document proposes a clustering-based approach to dynamically allocate bandwidth in wireless networks. It extracts student data from a university's course timetable to predict user distributions over time. It then applies K-means clustering to group buildings into wireless nodes based on expected user loads. This clusters student devices and allows wireless nodes to adapt their bandwidth allocation according to predicted user demands at different times. The approach is tested on a university campus network, extracting student data to predict building loads and applying K-means clustering to allocate optimal bandwidth across wireless nodes over time.
Civilizing the Network Lifespan of Manets Through Cooperative Mac Protocol Me...IRJET Journal
1) The document discusses a proposed cooperative medium access control (CMAC) protocol for mobile ad-hoc networks (MANETs) that aims to improve energy efficiency and extend network lifetime.
2) Existing CMAC protocols focus on throughput enhancement but fail to adequately consider energy efficiency. The proposed DEL-CMAC protocol aims to extend network lifetime by accounting for energy consumption at both transmitters and receivers.
3) Cooperative communication techniques that employ relay nodes can provide spatial diversity gains to reduce transmission power needs. However, the overhead of cooperation may outweigh these gains, so an efficient CMAC protocol is required to manage medium access for cooperative transmissions.

Dynamic Topology Re-Configuration in Multihop Cellular Networks Using Sequent...IJERA Editor
Cellular communications has experienced explosive growth in the past two decades. Today millions of people around the world use cellular phones. Cellular phones allow a person to make or receive a call from almost anywhere. Likewise, a person is allowed to continue the phone conversation while on the move. Cellular communications is supported by an infrastructure called a cellular network, which integrates cellular phones into the public switched telephone network. The cellular network has gone through three generations.The first generation of cellular networks is analog in nature. To accommodate more cellular phone subscribers, digital TDMA (time division multiple access) and CDMA (code division multiple access) technologies are used in the second generation (2G) to increase the network capacity. With digital technologies, digitized voice can be coded and encrypted. Therefore, the 2G cellular network is also more secure. The third generation (3G) integrates cellular phones into the Internet world by providing highspeed packet-switching data transmission in addition to circuit-switching voice transmission. The 3G cellular networks have been deployed in some parts of Asia, Europe, and the United States since 2002 and will be widely deployed in the coming years. The high increase in traffic and data rate for future generations of mobile communication systems, with simultaneous requirement for reduced power consumption, makes Multihop Cellular Networks (MCNs) an attractive technology. To exploit the potentials of MCNs a new network paradigm is proposed in this paper. In addition, a novel sequential genetic algorithm (SGA) is proposed as a heuristic approximation to reconfigure the optimum relaying topology as the network traffic changes. Network coding is used to combine the uplink and downlink transmissions, and incorporate it into the optimum bidirectional relaying with ICI awareness. Numerical results have shown that the algorithms suggested in this thesis provide significant improvement with respect to the existing results, and are expected to have significant impact in the analysis and design of future cellular networks.

The document summarizes a proposed scheduling technique called Real Time Conflict-free Query Scheduling (RTCQS) for wireless sensor networks. RTCQS aims to increase throughput for high data rate sensor applications while supporting real-time queries. It uses a query planner to construct transmission plans for queries as sequential conflict-free steps. A query scheduler then schedules the query instances, using preemption for higher priority queries or concurrent execution when no conflicts exist. The goal is high throughput, low latency, and adaptability to varying workloads.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

2. Abstract
• Mobile ad hoc networks (MANETs) are becoming increasingly common, and typical network loads
considered for MANETs are increasing as applications evolve.
• This, in turn, increases the importance of bandwidth efficiency while maintaining tight
requirements on energy consumption delay and jitter.
• Coordinated channel access protocols have been shown to be well suited for highly loaded
MANETs under uniform load distributions.
• However, these protocols are in general not as well suited for non-uniform load distributions as
uncoordinated channel access protocols due to the lack of on-demand dynamic channel
allocation mechanisms that exist in infrastructure based coordinated protocols.
• In this project, we present a lightweight dynamic channel allocation mechanism and a
cooperative load balancing strategy that are applicable to cluster based MANETs to address this
problem.
• We present protocols that utilize these mechanisms to improve performance in terms of
throughput, energy consumption and inter-packet delay variation (IPDV).

3. Existing System
• A distributed dynamic channel allocation algorithm with no optimality guarantees for a network
with a fixed a-priori control channel assignment.
• Alternatively, there are various game-theoretic approaches to the channel allocation problem in
ad hoc wireless networks.
• Multichannel model the channel allocation problem in multi-hop ad hoc wireless networks as a
static cooperative game, in which some players collaborate to achieve a high data rate.
• In multi-hop wireless networks, CSMA techniques enable the same radio resources to be used in
distinct locations, leading to increased bandwidth efficiencies at the cost of possible collisions due
to the hidden terminal problem.
• Different channel reservation techniques are used to tackle the hidden terminal problem. Karn
use an RTS/ CTS packet exchange mechanism before the transmission of the data packet.
• 802.11 distributed coordination function (DCF) uses a similar mechanism.

5. Proposed System

Ph: 9952077540
• In this project we propose two algorithms to cope with the non-uniform load distributions in
MANETs: a light weight distributed dynamic channel allocation (DCA) algorithm based on
spectrum sensing, and a cooperative load balancing algorithm in which nodes select their channel
access providers based on the availability of the resources.
• We apply these two algorithms for managing non-uniform load distribution in MANETs into an
energy efficient real-time coordinated MAC protocol, named MH-TRACE. In MH-TRACE, the
channel access is regulated by dynamically selected cluster heads (CHs).
• MH-TRACE has been shown to have higher throughput and to be more energy efficient compared
to CSMA type protocols.
• Although MH-TRACE incorporates spatial reuse, it does not provide any channel borrowing or
load balancing mechanisms and thus does not provide optimal support to non-uniform loads.
6. Advantages
• Increase the throughput
• Here we use scalable approach
• Reduce energy consumption

8. Conclusion
www.iistechnologies.in
Ph: 9952077540
• In this project we have not investigated the effects of upper layers such as the routing layer, and
instead focused on the MAC layer capability and local broadcasting service.
• Packet routing has a significant impact on the load distribution.
• Local link layer broadcasting service is directly used by some routing algorithms such as network
flooding.
• Moreover, it can be used alongside with network coding and simultaneous transmission
techniques for cooperative diversity.
9. Future Work
