Abstract:

Abstract Collctions of wireless mobile nodes constitute a Mobile Ad-Hoc Network (MANET), which is a transient network without a fixed infrastructure or centralized management. When they are within the wireless range of one another, nodes in such a network can directly communicate with one another. Communication occurs through intermediary nodes using many hops outside of the wireless range. In a MANET, nodes move randomly and freely, changing the architecture of the network and leading to connection failures between communicating nodes. With such a time-varying network topology, conventional routing methods like shortest path and link-state algorithms are ineffective. Protocols employed in such a setting must be able to deal with changeable topology and quickly identify an effective communication path. The work's goal is to create and refine a fresh routing algorithm for MANET. These modifications were put into the chosen multipath protocols and their effects were studied. Congestion-free and bandwidth-aware AOMDV (CB-AOMDV) uses both CFT and residual bandwidth evaluation to find the optimal route. The available bandwidth is utilized more effectively. Both performance and packet delivery are enhanced by this approach. The congestioen on the link and the hosts' remaining energy are both factored into ECAOMDV's pathfinding calculations. As a result, the lifespan of the pipeline is extended and the workload is distributed more fairly throughout the hosts. This protocol has lower power requirements and higher throughput. Increases in packet delivery rates are another benefit of this system. Hosts employing the Energy and Congestion aware AOMDV (ECAOMDV) protocol think about both congestion and energy levels when choosing an active routing. The simulation results demonstrate that the protocol has the potential to lengthen the path and fairly distribute packets across the hosts. Metrics measuring throughput are up. Experiments also showed that this approach increased packet delivery while using less energy than AOMDV.
