Abstract

In recent years, there has been a growing interest in wireless sensor networks. One of the major issues in wireless sensor network is developing an energy-efficient routing protocol. LEACH is very effective in enhancing nodes´ lifetime from routing´s aspect.This paper proposes an improved LEACH protocol for data gathering and aggregation in wireless sensor networks. Conventional LEACH includes distributed cluster formation, local processing to reduce global communication, and randomized rotation of the cluster-heads. The new protocol uses multi-hop routing instead of 2-hop routing in LEACH, and related algorithm is proposed. Simulation results show that improved protocol is more energy-efficient than conventional LEACH.
