Abstract
The routing data for associate infrastructure less network of Mobile Ad-hoc network is taken into account as an advanced task. Various protocols deal with this routing update like AODV, DSR, etc. All the way through this route construction generally the route failure happens & route repairing mechanism must be initiated whenever it’s needed. Currently this unsuccessful route must get replaced before the loss of information. In this method considering AODV there are 2 approaches that touch upon this link breakage. Link breaks between the routes may be handled either by reformation of latest shortest route from the supply to destination is made using intermediate.One among the key challenges during this context is that that one among the 2 is best and once to use that of the 2 route repair ways.In the existing approach to deciding in which condition to invoke Local Repair or Source Repair standard AODV uses an unchanging hop count based threshold as a basis in case of a link breakdown. With this type of repairing the mechanism problem arises is that in that type of network we cannot decide what algorithms to be applied at which point. For that reason to take decision same condition has to be identified. Herein also we should ensure that the decision of route repair mechanism must be pre-emptive so that loss of data can be avoided earlier than occurrence. This work proposes a novel Threshold oriented Preemptive Route Repair Algorithm for Multi-Hop Local repair in ADOV for MANET. In this proposed work focus is on early identification of link failure before its occurrence and network must know when to start route discovery if the link break occurs in the network.
