In MANET: An Improved Hybrid Routing Approach for Disaster Management

A disaster is an event that obstructs the regular course of events. Communication between nodes is severely hindered during disasters. As a result, an ad-hoc network method was necessary to manage global emergency circumstances. During disaster management, the role of information technology in terms of communication between nodes is critical. A mobile ad-hoc network is one that self-organizes and controls itself without the aid of centralized management in unpredictably changing circumstances. Mobile ad hoc network (MANET) technology can be highly helpful in emergencies. In a crisis, route discovery in MANET is the most important aspect of data transfer. Table-driven algorithms and link-state routing techniques, especially in a disaster, may not always deliver greater performance stressed out and in a lot of traffic. Low memory and power requirements make the hybrid technique ideal for quick convergence. Fast route discovery for network density is made possible by this study’s enhanced hybrid approach, which combines two on-demands and one table-driven routing protocol. The suggested approach was tested in a mock environment. Based on the outcomes of the simulation, when compared to the ad hoc on-demand distance vector (AODV) routing protocol, In terms of end-to-end delay, routing load and throughput, and data packet delivery density, it delivers a higher network density. The IHRP performs better and improves from 9% to 12%, according to results comparing it to the present regimen.
