    Performance evaluation of AODV based congestion control protocols in manet
    (Central University of Punjab, 2014) Bhatia, Bandana; Sood, Neha
    The network in which the users communicate with each other by forming a temporary network without any centralized administration is known as ad hoc network. Every node in ad hoc network acts both as a host as well as a router. The topology of these networks is highly deployable, dynamic and self-configurable. Because of the dynamic topology of Mobile Ad hoc Networks (MANETs), routing is an extremely challenging task in them. For ensuring reliable and efficient routing in MANETs, different routing protocols are defined. These routing protocols may follow proactive, reactive or hybrid approach. As many number of mobile nodes are transmitting the packets over the network, the chances of losing the packets over the network increases to a great extent due to link failures or may be due to congestion over the network because of large traffic flowing over the network. Also, when the size of data packets increases, it may lead to the congestion over the network which ultimately leads to the loss of packets. The existing routing protocols for MANETs do not support congestion control as they are not congestion adaptive. Many authors have proposed protocols based on Ad hoc On demand Distance Vector Routing Protocol (AODV) which are congestion adaptive and deal with the congestion over the network. This dissertation work discusses the congestion control protocols in MANETs and focuses on two congestion control protocols, AODV-I and EDAODV. Simulation results are gathered for AODV, AODV-I and EDAODV by varying the number of nodes and size of the data packets for four performance metrics, namely, routing overhead, throughput, end- to-end delay and packet delivery ratio (PDR).
