Abstract: By considering the number of gateways and gateway load balancing, this paper proposea a force-based greedy heuristic clustering algorithm. On this basis, it improves the hybrid Particle Swarm Optimization(PSO) algorithm and gives a gateway placement algorithm for Wireless Mesh Network(WMN). Simulation results show that the algorithm can effectively achieve the load balancing among gateways with less number of gateways, and improve the network throughput and the network performance.
