Improving the Performance of MANET Gateway Selection Scheme for Disaster Recovery

In this paper, we propose an improved MANET gateway selection scheme suitable for disaster recovery applications. Having an infrastructure less and decentralize features, MANET is well suited to bring the network back that has been collapse after a disaster. In this paper, we focus on improving throughput performance of MANET by designing a better gateway selection scheme. The key idea is to eliminate the congestion at each MANET gateway to improve the network performance. The main challenge is the mobility of nodes in disaster recovery environment. Simulation results show that the proposed gateway selection scheme can efficiently manage the traffic distribution at each gateway in order to maximize the network performance.
