Effect of a node´s death on behavior of the LEACH protocol and its descendants

Wireless sensor networks have gained major attention from most of the recent research community. One of the important issues in this type of networks is the inherent limited power of the network sensor nodes. Hierarchical routing protocols are incorporate of efficiently balancing the load on the sensor nodes. But, dice the death of some nodes to the network begins to deteriorate more and more. This paper describes the comparative analyses of LEACH protocol with its various descendants in the level on the influence of network after the event of the death of a node regardless the node (C-H node or member node). In addition, we have given some relief proposals to strengthen the network in particular cases and its implementation in Network Simulator (NS2).
