Performance analysis of AODV based congestion control protocols in MANET

MANETs are highly deployable, dynamic and self-configurable because of which routing is an extremely challenging task in them. AODV routing protocol used for routing purposes in MANETs is an on-demand routing protocol which do not support congestion control as it is not congestion adaptive. This paper discusses two congestion control protocols based on AODV in MANETs. Many authors have proposed protocols based on AODV which are congestion adaptive and deal with the congestion over the network. AODV-I and EDAODV are two congestion control protocols which deals with the congestion reactively. These two protocols are simulated on NS2 by varying the size of data packets. The analysis of these protocols is done with AODV by calculating the values for four performance metrics, namely, throughput, packet delivery ratio (PDR), routing overhead and end-to-end delay.
