An Improvement to LEACH-based Routing Algorithm

摘要

Wireless Sensor Networks consists of a huge number of small self-contained devices with computational, sensing and wireless communication capabilities. LEACH is a classical clustering-based protocol in wireless sensor network. In this paper, we propose an improved routing algorithm LEACH-WQ based on the analysis of LEACH protocol, which involves cluster head choosing, multi-hop routing and the building of its path. As a result the number of cluster head is constant and near optimal per round. Simulation results prove that the routing algorithm proposed by us has higher energy utilizing rate, and it helps prolonging the network lifetime..
