摘要： 在无线传感器网络(WSN)中，如何实现数据转发的高效节能是WSN路由协议的核心问题。在LEPS路由协议基础上，引入能量感知机制，结合扩散延时方法提出EALB路由协议。通过仿真实验验证了EALB能有效减少冗余数据的发送，达到节能和节点间负载均衡、延长网络寿命的目的。

Abstract: To make data transmission more energy-efficient is an essential design issue of Wireless Sensor Network(WSN) routing protocol. This paper proposes a new routing protocol: Energy-Aware and Load-Balance(EALB), which is based on Link Estimation and Parent Selection(LEPS) protocol and adopts energy-aware mechanism as well as broadcast delay method. Simulation results show that compared with LEPS, EALB reduces redundant data transmission and realizes the load balance.

Key words: WSN, routing protocol, load balance
