Abstract

Wireless sensor networks consist of small nodes with sensing, computation, and wireless communications capabilities. The energy efficiency is a key design issue that needs to be enhanced to improve the life span of the network. In this paper, we propose a Hierarchy-Based Multipath Routing Protocol (HMRP) for wireless sensor networks. In HMRP, the network will be constructed to layered-network at first. Based on the layered-network, sensor nodes will have multipath route to sink node through some candidate parent nodes. The simulation results show that our HMRP can improve the lifetime of sensor networks.
