WSN中基于事件触发的动态Cell多目标跟踪模型研究

为了研发更有效的基于WSN的多目标跟踪系统,对基于监测Cell的跟踪模型和VGA模型进行研究,提出基于事件触发的动态Cell跟踪模型:整个监控区域按VGA标准划分,LA做监控节点,其余节点休眠,当有目标出现时,LA节点唤醒相邻8个网格中的节点组成Cell进行实时跟踪。本文重点讨论同时针对多个运动目标的Cell跟踪过程。综合考虑能耗和实时性的需求,提出基于Cell跟踪的路由模型。通过实验证明该跟踪模型能及时有效的进行多目标跟踪。

Researches on events triggering multi- target tracking based on dynamic Cell in Wireless Sensor Networks

To develop more effective multi-target tracking system in Wireless Sensor Networks,researches have been made on the surveillant Cell tracking model and the VGA model.An event triggering multi-target tracking model based on dynamic Cell is brought up.The entire region is divided up on the VGA standard.LAs are monitoring and the remaining nodes are resting.As a target appears,LA awake all nodes in adjacent eight meshes to compose a tracking Cell.The point is multi-target Cell tracking process.Considering energy consumption and the demand for real-time,routing based on tracking is brought forward.The experiment proves that the model can be followed in a timely and effective multi-target tracking.
