中文摘要：

提出了一种基于分簇的移动协助（CMA）无线传感器网络路由协议。在圆形网络中,Sink以恒定速率做圆周运动,网络初始阶段根据应用时延要求和能量消耗确定移动Sink的运动半径,按照确定的Sink运动轨迹,将网络进行分簇。然后在Sink通信范围内确定一批普通节点作为汇聚点（RP）,最后Sink对汇聚节点的缓存数据以及其单跳范围内的簇头进行采集。仿真实验结果表明：与现有的几种路由协议相比,CMA在满足时延要求条件下有效地延长了网络生命周期。

英文摘要：

Propose a clustering-based routing protocol for mobility assistant（ CMA） wireless sensor networks（ WSNs）. Moving radius of the mobile sink is determined by application delay requirements and energy consumption in initial phase of networks,and the network is clustered according to certain sink motion trail. Select a number of common nodes as the Rendezvous point（ RP） within communication range of sink,finally sink gathers cache data of the RP node as well as clusters head within its one-hop range. Simulation results show that compared with several existing routing protocols,CMA effectively prolongs network lifetime in the condition of meeting delay requirements.
