Sensor node deployment in wireless sensor networks based on improved particle swarm optimization

Wireless sensor networks (WSNs) is always consist of stationary and mobile sensor nodes, sensor node deployment is one of the key topics addressed in the researches of WSNs, traditional virtual force(VF) algorithm is presented. This paper proposes a method of improved particle swarm optimization to solve the problem. The simulation results show that the improved particle swarm optimization has better performance on the sensor node deployment problem and reduce the network energy consumption and increase the whole coverage ratio.
