摘　　要：能量敏感是传感器网络设计中的一个基本要求,现有的基于位置的路由协议都没有考虑下一跳节点与源节点的距离,使得传输效率不高。本文通过引入有效传输(ET)概念保证每个前向节点比其前驱节点不仅更加靠近目标节点,而且更加远离源节点,提出一种基于ET的能量敏感的路由协议。仿真结果表明这种路由协议与其它一些协议比较起来,可以提供较低的能量消耗。Energy awareness is a basic requirement in the design of sensor networks. The existed position-based routing protocols have not considered whether the forwarding candidate is more farther from the source node with respect to its sender, which will give less efficiency. This paper introduces a novel concept of Effective Transmission （ET） that ensures each forwarding node is not only nearer to the destination node, but also farther from the source node with respect to its sender. An energy-aware routing protocol based on ET is proposed. The simulation results show the routing protocol is effective on the performance of energy consumption when compared with some other routing protocols.
