Research on Gateway Deployment for Throughput Optimization in Wireless Mesh Networks

At present, the architecture of the emergency communication network is a hotspot at home and abroad. Wireless Mesh network (WMN) is a new wireless network architecture suitable for emergency network requirements. However, the gateway deployment in WMN affects the overall performance of the emergency network. Aiming at this problem, we propose a gateway selection algorithm (MTMG), which considers both the gateway deployment cost and the link collision domain. In the case of ensuring full coverage of the network, the genetic algorithm is used to minimize the number of gateway nodes, and the bottleneck collision domain is used to calculate the maximum throughput to optimize the throughput. The simulation results show that the algorithm can reduce the number of gateway deployment effectively and improve the network throughput while ensuring that all nodes are fully covered.
