Dynamic Path Planning Method of Mobile Anchor Node Based on Direction Decision

GAO Meifeng;LIU Yang;Key Laboratory of Advanced Process Control for Light Industry,Jiangnan University,Ministry of Education;  
In the process of wireless sensor network location based on mobile anchor nodes,the path planning problem of mobile anchor nodes has important influence on the positioning performance. However,the existing path planning method does not take full account of the density and distribution of unknown nodes in the networks,the positioning efficiency is low and the cost is large. Therefore,a dynamic path planning method of mobile anchor node based on direction decision is proposed( Dynamic Path Planning Based on Orientation Decision-Classed Weighted,CWDP). Firstly,the unknown nodes in the network are graded according to the connectivity threshold. When the mobile anchor nodes enters the network area,according to the feedback information of the unknown nodes located in the communication range,the mobile anchor next moving direction is determined by using the hierarchical weight coefficient in real time. The simulation results show that the proposed method can effectively improve the localization coverage,reduce the localization error of the unknown nodes in the network and save the localization cost.
