Comparative Evolution of AODV Routing Protocol based on Link Life Time in MANET

Mobile Ad Hoc network (MANET) is an infrastructure less multi-hop mobile network which is combination of mobile nodes with wireless receiver and transmitter with bounded energy and storage space. With the development of mobile network and multimedia services, quality of service is become very crucial. In MANET delay, bandwidth, link stability, hop-count are major QoS parameter. Compare to wired network; large amount of packet loss, end-to-end delay and low throughput are the major problems in MANET which may be occur due to dynamic behaviour of mobile nodes, transmission error, link failure, node congestion. More ever QoS of real time application is become very tough. AODV, DSR, DSDV are leading protocols for MANET in recent years. This paper gives a sketch of AODV and various derived protocol along with QoS parameter such delay, bandwidth and link stability, so to analysis their performance.
