A Literature Survey on Congestion Control Schemes for Wireless Ad hoc Networks 1

Abstract – This paper briefly discusses performance optimization challenges of Ad hoc networks and cross layer congestion control in Ad hoc network. To improve the performance of wireless network, the MAC layer uses transmission data rate based on the channel signal strength information from physical layer and congestion information from network layer. Utilization of MAC layer is sent to DSDV as a congestion aware routing metric for optimal route discovery. The simulations show that rate adaptation in MAC layer improves the network performance in terms of throughput, delivery ratio and packet transfer delay; using congestion information from MAC layer in routing discovery improves the performance of the network benefited from overall network load balance
