Aiming at the traditional deployment methods of mobile nodes in Wireless Sensor Network(WSN),there are some problems like non-uniform distribution and incomplete coverage of the nodes.To overcome this,a new assignment deployment method of mobile nodes,which is based on improved Shuffled Frog Leaping Algorithm(SFLA) is presented from the angle of swarm intelligence algorithm.An optimal deployment model of mobile nodes is set up according to the nodes location information.Simulation results show that the improved SFLA has stronger global convergence ability than Particle Swarm Optimization(PSO),SFLA,Virtual Force Algorithm(VFA) in the application of deployment of mobile nodes,and reduces the wasted energy of the mobile nodes at the same time.
