Abstract:
With the increasing popularity of wireless network and its application, mobile ad-hoc networks (MANETS)
emerged recently. MANET topology is highly dynamic in nature and nodes are highly mobile so that the rate of link failure
is more in MANET. There is no central control over the nodes and the control is distributed among nodes and they can act
as either router or source. MANTEs have been considered as isolated stand-alone network. Node can add or remove at any
time and it is not infrastructure dependent. So at any time at any where the network can setup and a trouble free
communication is possible. Due to more chances of link failures, collisions and transmission errors in MANET, the
maintenance of network became costly. As per the study more frequent link failures became an important aspect of
diminishing the performance of the network and also it is not predictable. The main objective of this paper is to study the
route instability in AODV protocol and suggest a solution for improvement. This paper proposes a new approach to reduce
the route failure by storing the alternate route in the intermediate nodes. In this algorithm intermediate nodes are also
involved in the route discovery process. This reduces the route establishment overhead as well as the time to find the
reroute when a link failure occurs.
