Aiming at problems of low coverage rate and high cost existing in node localization technology of WSNs,moving beacon nodes technology is used,optimization strategy for path planning of the Gauss-Markov mobile model(GMM) is put forward,to make the beacon node moving more effectively in the detected region and improve coverage rate of unknown nodes,influence of coverage of different parameters on the unknown nodes is analyzed.The simulation results show that the proposed method covers the unknown nodes rapidly and has high coverage rate.And can well adapt to application requirement of large scale randomized nodes layout.
