Coverage under certain conditions, with minimum sensor nodes to complete the coverage area and connectivity in wireless sensor networks has become a challenging one with the core issues. To this end, we propose a target associated with optimal coverage and connectivity control method using a double square to the target node within the planning area within the square, correlation model obtained by the sensor node and the destination node, for the entire coverage area is the use of probability determined to meet the minimum expectations of sensor nodes under cover conditions, and gives a probability model and the reasoning process connectivity square area outside edge node. Experimental results show that the error theoretical values with the simulation results of the method is less than 7.02%, to verify the effectiveness of the algorithm, reducing the allocation of network resources, you can better assess the performance of network coverage and connectivity.
