DECISION MAKING APPROACH TO PREFER ROUTE REPAIR TECHNIQUE IN AODV ROUTING PROTOCOL OF MANET

Shikha Patle, Purushottam Kumar

Abstract: MANET is a dynamic environment of mobile nodes and suffers link failure problem i.e. due to node mobility, loss of energy, node failure etc. To overcome the broken link problem, initiated route repair mechanism. The suggested two route repair techniques are used to repair the broken link of the network. Either the routes can be repaired by re-establishing a new route starting from the source node or the routes can be repaired by the node that detects the link break along the path. The mechanism is proposed to prefer route repair techniques on the basis of decision. According to this approach, the different route repair values are defined on the basis of the active path of network and calculate the link break value of the network for finding in which location the link break is occurring to initiate route repair mechanism. For implementation, apply the proposed approach on an AODV routing protocol and check which route repair techniques are used. Simulate the results on the basis of different parameter i.e. sent data packets, received data packets, dropped data packets and energy consumption.
