【 摘 要 】

Picking to meet certain condition with minimal coverage, sensor nodes to complete coverage and connectivity for wireless sensor networks has become a challenging one of core problems. For this reason, one kind based on the node mobile strategy optimal coverage algorithm was proposed. Firstly, the sensor node and the target node mapping relation model was established, which using geometric graphic in the square will target node planning to the inner square area, through to the mobile node scheduling strategy for the entire coverage area for effective coverage, achieving the goal node complete coverage of the objective. Secondly, probability expectation values were obtained through the algorithm to meet under the conditions with minimal sensor nodes, and the optimal coverage and connectivity probability models were given. Finally, the experimental results show that the algorithm can not only using the least nodes to complete the effective target area to be covered, but in reducing the network energy consumption has also greatly improved, simultaneously reducing the cyber source configuration and improving the network life cycle.
