Fault occurrence in LEACH protocol in wireless sensor networks

In wireless sensor network, energy utilization is one of the most important parameter to be discussed. While doing communication, nodes are interconnected to create a network and sinks are placed on a board to carry the information to the base end also called sink. Maximum energy is being used for transmission of information. For increasing the lifetime of the network of WSN, we need to use lesser energy from each node. To accomplish this, the idea of clustering comes. But static clustering has its limitations and more chances of fault. So to diminish the fault occurrence, a hybrid approach of clustering is introduced in our proposed method. Performance evaluation is when fault has occurred. The performance metrics used in this are delay, throughput, packet loss and energy utilization. Simulator tool used is NS2 2.5.
