First Node Die (FND) Time Enhancement in LEACH Protocol

Naveen Chawla | Ashish Jasuja

Abstract: In wireless sensor networks, the fixed battery condition is dominating. Generally nodes are equipped with a fixed battery having limited working period. As soon as the battery becomes empty the node no longer contributes in network and becomes a dead node. For improving the lifetime of any wireless sensor network the method is implementation of an efficient protocol that can efficiently use the limited capacity battery. In wireless Ad-hoc networks the LEACH protocol is implemented. In this protocol a clustering based scheme is used. This paper presents the improved LEACH protocol for first node die (FND) time enhancement. The results reveal that changes made selection process of a cluster head improves the network efficiency. The approach is to vary the cluster head selection probability along with the threshold level. The protocol works to prolong the first node die time (FND). The proposed algorithm is simulated on MATLAB platform and comparison is done between standard LEACH and proposed LEACH protocols.
