Exploring Link failure and Route Identification and Migration in MANET

Abstract

Mobile Ad Hoc Network (MANET) is recognized as the most considerate architecture in wireless and unguided networks. It is a wireless network of mobile devices which are configured itself. The prime challenge is created due to repetitive transition of nodes along with their mobility in the infrastructure less network is the failure of link, if routing protocol give quickly responses to the network topology than it will be avoided. By reactive protocol like AODV, the rate of dropping of packet, delay of end-end delivery will increase and the rate of delivery of packet will be reduced. As having such disadvantages, we suggest a new Algorithm which acquaint a method of link failure prediction and consequently execute a rapid local route repair. Simulation proves that this new algorithm minimize rate of dropping packet and delay of end-end delivery and amplifies increase in rate of delivery of packet. We can reduce the delay results by reverting information of failure of link to the initiator which is one of the major advantages of this new approach. It will result in much better and efficient Ad hoc On-Demand Distance Vector route finding protocol for following metric parameter: delay, dropping rate and overhead.
The main challenge in case of transition of nodes along with their mobility in the infrastructure less network is the failure of link. Although, various mechanisms are already been deployed to quickly discover alternate route for packets by taking into account the parameter of counting the intermediate node, still they are not prominent to delay of end to end delivery. So, the paper also introduces a concept for Immediate Route Diversion protocol, in which the alternate routes are discovered immediately by taking into account the parameter such as route cost and number of intermediate nodes to traverse. The paper also focuses on implementation of the partial network structure awareness method such that the shortest route can be found quickly. To perform this maintenance of cache at each node is required to reroute the packets to receiver whenever failure of link occurs. The solution proposed will reach maximized throughput, reduced delay of end to end delivery and immediately find alternate path in less time as compared to existing systems.
