Abstract: In this paper, we deal with congestion control for multi-flow traffic in wireless mobile ad-hoc networks (MANET). For simulations, we used NS-3 open source network simulator considering Ad-hoc On-Demand Distance Vector (AODV) and Optimized Link State Routing (OLSR) routing protocols. We present the MANET performance considering random waypoint mobility model for different number of nodes and different area sizes, by sending multiple UDP or TCP flow traffic in the network. We investigate and compare the packet delivery fraction (PDF) and throughput. Simulation results show that the performance of the network is high when the number of nodes is 20 and maximum speed is 6 m/s for multiple flows. We found that coupling congestion control mechanisms between multiple flows have problems in some cases.
