摘要：针对已有的无线传感器网络（WSN）路由算法在具体的实际应用中存在的问题，提出了适合实际应用的路由算法的目标，并设计了一种能量敏感的路由算法，以节省能量消耗从而达到延长整个网络生命周期的目的。该算法在已有的分簇算法基础上加入休眠机制，使未承担传输数据的节点进入休眠状态，从而达到节能目的。在GAINZ节点组网环境中实现了基于该路由算法的原型系统，并对该算法的性能和效率进行了测试。研究结果表明，在实际应用过程中该算法能有效地提高网络的生命周期。

Abstract: Aiming at the existing problems of the typical wireless sensor networks(WSN) routing algorithm, the purpose of the routing algorithm in wireless sensor networks was put forward. In the meantime, energy aware routing algorithm was designed to reduce the energy consumption so as to prolong the network lifetime.On the basis of reliable routing clusters,the node which cannot transmit data comes into the state of sleep thus energy saving can be achieved.Prototype was implemented in the network node where the function and the efficiency of the routing algorithm was tested. The results indicate that the algorithm can prolong the network lifetime.
