无线传感器网络中面向目标追击应用的信息分布研究

Research of Information Dissemination in WSN-aided Pursuer-evader Application

无线传感器网络辅助的目标追击是一项很有前景的应用.本文针对追击者-逃跑者应用快速获取目标信息的需求,提出一种基于单覆盖的均匀存储算法SCUS,用于高效地分布信息.每个信息分布节点使用该算法在网络中选择一组存储节点,将目标信息分布到这组节点上,使得追击者无论在网络的哪个位置都可以在其通讯范围内高概率地获取目标信息的一份拷贝.仿真结果表明,SCUS算法只使用较少的节点就能够实现较高的覆盖率,而且在节点密度适中、随机分布的传感器网络中能够实现较好的负载均衡.

WSN-aided target tracking is a promising application. To meet the requirement of timely targets information acquirement in tracking scenario, this paper proposes a single coverage based uniform storage （SCUS） algorithm for efficient information dissemination. The information holders will choose a set of storage nodes and send information to them, guaranteeing that regardless of their position, pursuers can obtain a copy of information with high success probability in its communication radius. Simulation shows that only a small number of nodes are employed to achieve high success rate, and when nodes are randomly deployed, load balance can be achieved with moderate node density.
