Sensor Node Scheduling in WSN Based on Improved Particle Swarm Algorithm

In order to reduce the node energy consumption and prolong the life cycle of wireless sensor network,a node scheduling method based on improved particle swarm algorithm is proposed.Firstly,the system model is set up using the coverage and the sleep node as the goal.Then the coding method for particle,the fitness function and the self suitable dynamic inertia weight is designed,the specific algorism using the improved particle algorism for sensor node scheduling in wireless network is defined.The simulation experiment shows the method in this paper can realize node scheduling in wireless sensor network and high coverage by using less working nodes and iteration time,and compared with the other methods,it has the rapid coverage and global optimizing ability.
