Increasing the Performance of Reactive Routing Protocol using the Load Balancing and Congestion Control Mechanism in MANET

Nowadays, routing and the improvement of reliability along with the load balancing and congestion control are the most important and challenging concepts in ad-hoc networks. However, there are some constraints in the bandwidth and the communication range due to the different utility of routing in the Mobile Ad Hoc Network (MANET).These restrictions, in addition to the dynamic network topology, are causing more complexity of routing and data transmission. These problems make the use of conventionalmethods inefficient, especially in the congestion and traffic control. So, there is a need to propose new solutions for these kinds of networks. This study has used the multipath routing based on the original protocol Ad-Hoc On-Demand Multipath Distance Vector (AOMDV). It proposes an appropriate protocol for the congestion control and balances the favorable loads in the routes. The proposed algorithm is based on different parameters that prepare the fittest multipaths based on the most efficient routes from the source to the destination, and then it makes a proper traffic distribution pattern in the middle routes based on the congestion analysis of the routes. Simulation results with NS2 shows improvements in the throughput, packet delivery ratio and delay in comparison to the Load Balancing Maximal Minimal Nodal Residual Energy (LBMMRE), Multipath Load Balancing Technique for Congestion Control (MLBCC), and AOMDV routing protocols.
