Guan Zhi-ya · Jisuanji fangzhen · 2015
The coverage optimization of the heterogeneous sensor mobile network is researched. In order to improve the node coverage efficient,this paper proposes a algorithm which puts forword a virtual force factor into the particle swarm optimization,based on analysis of the traditional virtual force algorithm defects. Firstly,the network coverage efficient is taken as the optimization goal,and a mathematical model is set up. Secondly,the adjusting distance threshold parameters of the virtual force affect the speed and position renovation of particle swarm update process in the algorithm,and the local extremum can be prevented. Finally,the simulations are carried out to test the algorithm performance. The simulation results show that the proposed algorithm improves the network coverage and the convergence speed.
