LEACH is one classical protocol in wireless sensor network, which is a clustering-based protocol with good performance. In this paper, an improved routing algorithm based on LEACH protocol will be proposed, which involves cluster head choosing, multi-hop routing and the building of its path. Simulation in MATLAB, an improved routing algorithm has higher energy utilizing rate, and it helps prolong...
Cluster-based routing protocol is currently a hot research in wireless sensor network. In this paper, we propose an improved method RECHS(Redundant and Energy-efficient Clusterhead Selection) for LEACH protocol to balance network load and to extend the network life. In order to selecting reasonable clusterheads, our scheme first selects initial clusterheads and initial redundant clusterheads. By comparing...
