Mobile sensor networks node distribution optimization based on minimum redundant coverage

摘要

In the research on mobile sensor networks, the proper deployment of sensor nodes directly affects the working effect of a mobile sensor network. For the sensor networks constructed by random distribution, better sensor coverage can be achieved by topology adjustment utilizing the mobility of the sensor nodes. Aiming at the optimization of node distribution in mobile sensor networks, a multi-object node distribution optimization scheme based on minimum redundant coverage is proposed. Simulation results show that the proposed scheme can quickly achieve node distribution optimization of a mobile sensor network, increase the effective coverage rate, reduce network redundant coverage, extend network lifetime, and achieve global optimization of the deployment of the mobile sensor network.
