Research and Improvement of LEACH Protocol for Wireless Sensor Networks

Article Preview

Abstract:

The data transfer of wireless sensor network (WSN) can not be separated with routing protocol, Energy efficiency is one of the most important factors in wireless sensor networks. In this paper based on the uneven distribution of the LEACH cluster head and the different lengths and base station communications, we present a improved LEACH algorithm which refers to remaining energy and optimal cluster heads. Computer simulation using NS2 reveals that the proposed protocol reduces the energy consumption compared with the existing LEACH protocol.
