Comparative analysis of AODV routing protocols based on network performance parameters in Mobile Adhoc Networks

Power deficiency of the nodes, multi-hop wireless connectivity, and high frequency of variation in topology of the network are major challenges that a Mobile Adhoc Network (MANET) has to face due to which it is very demanding to develop a dynamic and efficient routing protocol for this network. Adhoc On Demand Distance Vector (AODV) is an efficient reactive routing protocol in MANET in which the route is established only when it is required, so this protocol minimizes the overhead routing by not consuming enough energy in continuous route maintenance and repairing at time if there is no route request. In resource constraint environments, like an MANET, AODV protocol satisfies the necessary conditions of routing by considering stimulating matters such as highly mobile nodes, frequent link failure, limited battery power, variation in topology, satisfying quality of service. There are many improved AODV protocols, which are implemented for better network performance and intelligent routing. This paper presents a detailed study and comparative analysis of three leading protocols of MANET.
