Performance Evaluation of SEP, LEACH and ZSEP under the Influence of Network Area

In a Wireless Sensor Network, there are many number of nodes deployed randomly in the network. Though, these nodes are very tiny in size and thus are battery constrained and in most cases it is not feasible to replace it. Therefore energy consumption is a very important issue in wireless sensor network and hence, the network should be setup such that they can sustain for longer period and nodes can deploy energy efficiently. According to the requirement in the wireless sensor network, selection of right kind of protocol is also necessary as it can significantly affect the performance of the network. One of the requirements in setup of a wireless sensor network is its network area. This paper compares and analyses the performance of three protocols which are LEACH, SEP and ZSEP under the influence of varying network area. One of the attacks which affect the network is sinkhole attack. This paper mainly includes the optimization of data packets and data route for sinkhole attack using weight function over the network based on genetic algorithm and compare the results with and without optimization of sinkhole attack in the network.
