Congestion Avoidance Mechanism in Adhoc On-Demand Distance Vector Routing Protocol for Mobile AdHoc Networks

The Mobile AdHoc Network (MANET) is a wireless network of mobile nodes with limited energy and bandwidth that operates in a dynamic environment. It is based on decentralized management. Because of the limited amount of resources available, maintaining long-term contact with a large number of activities in a dense network is difficult. It is possible to communicate effectively in a light network without a congestion control strategy by using Adhoc On-Demand Distance Vector (AODV). Congestion, on the other hand, occurs in dense networks because of the high volume of traffic and the need to send packets in a continuous stream. Increased energy consumption and a shortened network lifespan are both consequences of congestion. With higher QoS in high-density networks, this research proposes a Congestion Avoidance Mechanism (CAMA) for AODV to reduce congestion. In order to reduce energy consumption and end-to-end delay while simultaneously improving packet delivery ratio and throughput, the suggested architecture makes use of the cross-layer idea. The suggested CAMA's performance assessments are superior to those of the Congestion Control AODV (CCAODV) and the AODV.
