Deployment is an important issue in wireless sensor networks(WSns).Most of recent researches focus on the optimal deployment patterns for full-coverage *** practice, there are only finite number of nodes can be used in WSns applications, which cannot guarantee that the entire region can be monitored;On the other hand, the information generated from monitored objects is distributed unevenly in the monitored *** to get a reasonable network deployment with the finite number of sensors becomes a practical problem, which should not be neglected. From all above, we propose a new coverage problem in WSns named n-nodecoverage, which refers to using the limited number of nodes to achieve maximum information *** this problem we use the information obtained from the monitored region as the new evaluation standard for network *** the basis of this standard, we construct the n-nodenetwork coverage model and convert the deployment problem to a combinatorial optimization problem, we present a heuristic optimization deployment scheme, the OPEn, to solve the *** results show that the OPEn can effectively improve the performance of sensor network coverage and provide practical guidance for deployment of WSns.
