Performance analysis of routing for traffic variation in WSN

Wireless Sensor Network (WSN) consists of sensor nodes which are randomly distributed over the network. These distributed sensor nodes have the ability to monitor environmental conditions. In WSN when nodes are densely distributed, congestion may occur in the network. In order to prevent congestion, fair allocation or sharing of resources to these nodes is necessary. Fairness maintains the network traffic and prevents congestion. Fair distribution of energy and traffic enhances network lifetime. In this paper we discuss fairness topic in routing protocols focusing more on its influence on resource allocation and network performance. This paper describes performance analysis of existing routing protocols for traffic variation in WSN. Simulation result shows the suitability protocol for grid topology in terms of packet delivery ratio, throughput, delay, average energy consumption, control overheads and routing overheads.
