Abstract: This paper presented an algorithm based on improved swarm optimization method to deploy the nodes, network coverage was the objective function, the deployment of sensor nodes would be formalized as a combinatorial optimization problem, and the basic swarm algorithm had been improved. The simulation results show that the this method can be in the target area with a relatively small cost to complete the distribution of sensor network node is optimized to reduce network energy consumption, improve the network’s overall coverage.
