面向单目标跟踪的临时簇构建算法研究

在目标跟踪中引入分簇机制使得跟踪计算任务可以以簇为单位进行,也可以在持久跟踪中将任务在簇间进行切换;文章针对无线传感器网络单目标跟踪提出一种临时簇构建算法(TCA),算法从感知到目标出现的节点中选出合适的节点,组建起临时簇进行目标跟踪运算,算法采用令牌传递方式来防止多个簇同时跟踪一个目标,使绝大多数节点均处于休眠状态;仿真实验结果表明,TCA组簇快速且能有效地控制整个网络的能耗。

A Temporary Clustering Algorithm for Single Target Tracking

With clustering in target tracking,calculation tasks could be allocated according clusters.For long time tracking,tasks also could switch between clusters.This paper proposes a single target tracking oriented temporary clustering algorithm(TCA).It chooses a suitable node in active nodes which have sensed the target to build a temporary cluster for tracking calculation.TCA uses token-passing method to avoid multiple clusters working for one target so that most of the nodes are sleeping.The simulation shows that TCA could build clusters quickly and control the energy consuming efficiently.
