    AODV Based Congestion Control Protocols: Review
    (IJCSIT, 2014) Bhatia, Bandana; Sood, Neha
    Ad- hoc network is defined as the network in which the users communicate with each other by forming a temporary network without any centralized administration. Here each node acts both as a host as well as a router. They have highly deployable, dynamic and self-configurable topologies. Various routing protocols are defined for MANETs. These protocols may follow proactive, reactive or hybrid approach. Due to many number of nodes transmitting packets over the network, the chances of losing the packets over the network increases to a great extent. Also, with the increase in size of data packets, the congestion over the network increases which may lead to packet loses. The existing routing protocols for MANETs do not support congestion control as they are not congestion adaptive. There are many proposed protocols that are congestion adaptive and deals with the congestion over the network. This paper discusses congestion control protocols in MANETs. Also, three congestion control protocols, EDAODV, AODV-I and CRP, are discussed. Simulation results are gathered for AODV by varying the number of nodes and size of the data packets for four performance metrics, namely, throughput, routing overhead, packet delivery ratio and end-to-end delay.
