Performance Evaluation of energy saving in WSN by Using Simulator NS2

Energy control is the most important problem for wireless sensor networks, and the design of an efficient energy strategy for prolonging the whole networks lifetime. The focus of this paper is to present the energy control strategy in energy-efficient routing protocols for wireless sensor networks. I have taken packet delivery fraction, End to end delay and Energy consumption Performance metrics to compare these schemes by using NS-2.34 simulator. Packet delivery fraction is the ratio of the data packets delivered to the destinations to those generated by the sources. End to end delay is the total latency experienced by a packet to traverse the network from the source to the destination. Energy consumption is the total number of energy consumed for packets transmitted and packets receiving during the simulation. By using these parameters I have compared with LEACH, GAF and DEED energy efficient routing protocol.
