IMHT: Improved MHT-LEACH protocol for wireless sensor networks

Abstract

Low Energy Adaptive Clustering Hierarchy (LEACH) protocol is considered as one of the most important protocols that are frequently used in the Wireless Sensor Network (WSN). Many protocols were developed to modify and improve the LEACH protocol. The multi-hop technique (MHT-LEACH) is one of these protocols, which appeared to improve the performance of the LEACH protocol. In this paper, an improved multi-hope technique (IMHT-LEACH) is proposed. Instead of distributing all the Cluster Heads (CHs) into two levels as in the MHT-LEACH, the IMHT-LEACH distributes all the CHs into a number of levels. It suggests a new technique to route the data to the Base Station (BS) through the levels. Simulation results indicate that the IMHT-LEACH improves the lifetime, stability and throughput of the WSN comparing with the conventional LEACH and the MHT-LEACH protocols.
