EiP-LEACH: Energy influenced probability based LEACH protocol for Wireless Sensor Network

Abstract

Design and development of energy efficient routing protocols for Wireless Sensor Network (WSN) is one of the active research fields. Cluster based routing protocols have proven to be energy efficient and LEACH is one of most popular cluster based routing protocol for WSN. But, LEACH suffers from several drawbacks such as possibility of choosing a low energy node as Cluster Head (CH), non-uniform distribution of CHs, etc. In this paper EiP-LEACH (Energy influenced Probability based LEACH) protocol is proposed which is an enhanced version of LEACH protocol that is influenced by the energy parameter for CH selection. EiP-LEACH helps in deciding the better CH nodes and thereby contributes towards network life prolongation. EiP-LEACH is compared with basic LEACH in terms of number of alive nodes, average energy depletion, First Node Dead (FND) and Last Node Dead (LND) and found that EiP-LEACH is far better.
