摘要：In the process of multi-objective coverage, due to a large number of redundant data which makes for the decrease of effective coverage and high energy consumption, relevant researches are being carried out. For this purpose, a Multi-Targets K-Coverage Preservation Protocol (MTCPP) is proposed. First, the affiliation between sensor nodes and target nodes is constructed through the network model and the solution for coverage expectations of monitoring area is given. Second, in terms of network energy conversion, the network energy is balanced by the schedule of sensor nodes while different qualities of network coverage can be gained through energy conversion among different nodes. Finally, simulation results show that the protocol can decrease the number of active nodes effectively under some coverage requirements, prolonging the network lifetime.
