%X How to control coverage effectively, reduce energy consumption and prolong the lifetime of network in a certain coverage condition is an important researching project in WSN. An optimized coverage algorithm with efficient energy is proposed in this paper. With the help of greedy algorithm and the theories in geometric graphics, node energy in target coverage area is constructed in a network model of normal distribution. Selecting optimum subset through data collection and retrieval and transferring scheduling mechanism of nodes dynamically can reduce the energy consumption of network effectively, improve the covering ability of nodes and optimize the amount of nodes. The simulation experiment shows that this algorithm can prolong lifetime of the whole network at the least cost with better suitability and stability.
