Maximizing Bandwidth Utilization and Multipath Routing for Control Congestion in MANET

This paper presents a novel Maximize Bandwidth utilization and Multipath Routing for Congestion Control (MBMRCC) scheme designed to address congestion issues in MANETs effectively. The MBMRCC scheme integrates multipath routing with adaptive rate control to enhance data throughput and minimize packet loss. In MBMRCC proposed scheme, multiple paths among sources and destinations are established using for enhance the multipath on demand protocol ability in dynamic network. This Ad hoc On-demand Multipath Distance Vector (AOMDV) routing approach distributes the data load across more than two paths, thereby reducing the congestion on any established path. Concurrently, the data rate control approach is able to handle data transmission rate based on real-time network conditions, such as node mobility, link stability, and current congestion levels. Simulation results demonstrate that the MBMRCC scheme significantly outperforms traditional single-path routing protocol AODV and Multipath routing AOMDV i.e. existing congestion control mechanisms in MANETs. Significant performance metrics such as throughput, packet delivery ratio, overhead and end-to-end delay performance are network favorable. The adaptive nature of the proposed scheme ensures robust performance in highly dynamic and heterogeneous network environments, making it a viable solution for various MANET applications, including disaster recovery, military operations, and mobile social networks. The MBMRCC scheme's ability to efficiently manage network congestion and enhance data transmission reliability underscores its potential to enhances the overall performance of MANET.
