In the process of coverage for multiple targets, the existence of a large number of redundant data decreases the effective coverage of monitoring area and increases the energy consumption of network. Therefore, this paper proposes a Multi-Targets K-Coverage Preservation Protocol (MTCPP). Firstly, the de-pendency of sensor nodes and target nodes is established by the network model, and the method of monitoring region coverage is given. Secondly, the network energy balance is achieved by using sensor node scheduling mechanism. Finally, the simulation experiments show the protocol can effectively...
