To address the problem of choosing the optimal cascaded movement path when mobile sensors are used to repair cove-rage holes in wireless sensor networks,the optimization method of choosing cascaded movement paths is proposed based on the number and the energy of intermediate cascaded nodes.The energy availability and the decisive energy of movement paths are gotten by computing the energy availability of intermediate nodes.Finally the optimal movement path is choosen by the multi-objective.The energy consumption of mobile sensors are balanced effectively,and the energy of the entire network is fully utilized.So the network lifetime is extended.The simulation results show that the proposed method has a higher energy efficiency than the standard cascaded movement.
