Natural disaster can strike at any time and in any place. Once it has occurred, it can ruin large regions, cause damage to houses and buildings, and destroy physical communication infrastructure. Therefore, a network backup is required in the disaster recovery area because victims will want to contact their important person to update the current situation as soon as possible. A mobile ad hoc network (MANET) is a collection of mobile devices that dynamically communicate with each other without any physical infrastructure. This feature offers a solution for communication problems during disaster recovery and keeping communication in disaster recovery areas alive. In this paper, an efficient routing scheme (GWRS) is proposed to eliminate the congestion that occurs when people in a disaster recovery area want to connect to a network. This new scheme provides a flexible and feasible approach in determining the best route. The routing scheme will simplify the selection of routes and prevent nodes from broadcasting packets to the entire network. In addition, this scheme eradicates any redundant nodes in each level of the routing table. These schemes have been simulated in a realistic environment of disaster recovery area. Ad-Hoc On-Demand Distance Vector (AODV) and Destination Sequenced Distance Vector (DSDV) routing schemes were also selected to be simulated in the same environment because these schemes show the best performance for reactive and proactive categories in emergency scenarios. Then, the performance of the proposed scheme was compared to these two schemes and evaluated through computer simulations using OMNET++ simulation tools. The results have shown that our proposed method has better results.
