Abstract

The invention provides a distributed type target tracking method of a mobile wireless sensor network, which solves the problem of low tracking accuracy in the target tracking of a traditional mobile wireless sensor network. The distributed type target tracking method comprises the following steps: a distributed type algorithm is used for predicting the position of a target in next tracking period, the cooperative matching of static nodes and dynamic nodes in a mobile wireless sensor network is considered, and all mobile nodes move towards the position of the target according to the information and acquire more accurate information of the target. The distributed type target tracking method provided by the invention has the advantages that the accuracy of target tracking of the mobile wireless sensor network can be effectively improved, the dynamic connectivity of the network is ensured, the target tracking efficiency is improved, the target tracking period is shortened, and the target tracking execution process is accelerated.

Description

technical field [0001] The invention relates to a distributed target tracking method of a mobile wireless sensor network, which mainly adopts a distributed algorithm to enable each mobile node to independently calculate its own moving path to realize target tracking, and belongs to the application of wireless sensor network, target tracking and distributed computing cross-technology field. Background technique [0002] A wireless sensor network is a wireless network composed of a large number of stationary or mobile sensor nodes in a self-organizing and multi-hop manner. Its purpose is to cooperatively perceive, collect, process, and transmit information about sensing objects in the geographical area covered by the network and report to users. . A large number of sensor nodes send the detected data to the user through the sink node. Mobile wireless sensor network is a new form of sensor network that is expanded after adding mobile nodes on the basis of static wireless sens...
