Recently, wireless sensor network has become the active research topics in academics and industries. The important things to be considered in designing of protocols do sensor network are minimizing the energy dissipation and network lifetime. The wireless sensor network consists of distributed devices known as sensor nodes which monitor physical and environmental conditions and communicate with nearby sensor node via radio broadcast. The authors will focus on primarily on the extended leach protocol to increase the network lifetime of the cluster based wireless sensor network.
