Wireless Mesh Network Deployment through Gateway Selection in Disaster Area

As communication services turns very important in disaster affected areas, the recovery of the remaining infrastructure becomes essential. Wireless Mesh network (WMN) proves to be a cost effective technology that provides backbone infrastructure to yield city-wide network access. Due to the self-recovery characteristics of Wireless Mesh Network (WMN), it has been used as an appropriate solution for network access in disaster areas. Throughput is used for evaluating the performance of the WMN. In this paper, we propose a gateway selection method to connect the destroyed network to an external network. Selection of different wireless mesh routers as gateway results in different system performance. The gateway is selected in a manner to maximize the system throughput. The simulation results show that effect of gateway selection of nodes on the system performance. The simulation is done using network simulator (NS2).
