An optimal coverage control algorithm with joint sensing (OCCAJS) is proposed to solve the problem of rapid consumption of network energy resulted from the large number of redundant nodes in the process of wireless sensor network coverage. The algorithm presents the solving process of maximal seamless coverage in the case of joint coverage of three nodes. Two methods are given, one calculates the expectations of coverage quality when sensor nodes are covered in the monitoring area and the other determines coverage rate when the expectation of a sensor node is compared with those of neighbor nodes. Moreover, when redundant coverage exists, the calculation process of the coverage rate for any sensor node in redundant coverage is presented by using ratio quotient. Simulation results and comparison with some existing algorithms in coverage quality and network lifetime show that the proposed algorithm improves the average performance about 11.02% and 13.27%, respectively. The proposed algorithm not only improves the coverage quality, but also suppresses the rapid consumption of nodes energy and the network lifetime is prolonged.
