摘　　要：针对无线传感器网络对固定划分子区域的不定期监测这一特定应用,结合定向扩散及聚簇的路由协议,提出一种新的路由协议ASRP,并对该协议的设计思想及执行过程进行分析和论述,包括监测区域内首领的选举机制以及监测区域外从关键点到基站的传输路径的建立。实验仿真表明该协议可有效均衡节点能耗,适用于上面提及的特定应用。Based on the specific application of monitoring fixed parts of the whole sensor network at unfixed time,a novel routing policy named ASRP is proposed combined with the idea of directed diffusion and cluster-based routing protocol.The designing idea and the execution process of the protocol are analyzed and discussed,including the leader election of the monitoring area and the setup of path from critical node to base station out of the monitoring area.According to the result of simulation,this protocol can efficiently balance the energy cost of nodes,hence can be applied to the specific application mentioned above.
