Handling multiple failures in IP Backbone network using LOLS along with AOMDV for detecting and avoiding wormhole attack

Abstract- It has observed that IP networks are susceptible to many kinds of failures and attacks but there are many solutions to provide another network or network path by rerouting method. But most of the solutions can handle only single failure and drops the packet or causes the loops. So we propose Localized On-demand Link State (LOLS) routing protocol. LOLS can surely handles the packet forwarding till the destination even in presence of multiple links. As LOLS can send a packet even with multiple failures but it fails when there is an presence of any kind of network attack. Among the various attacks possible in IP networks wormhole attack is one which is treated as a very severe attack. LOLS can handle multiple failures but it cant detect the network attacks. As LOLS is unable to handle any kind of attack and this is the reason why we are working on LOLS as well as AOMDV algorithm. In Wormhole attack a harmful node records packets at one end in the network and tunnels them to another harmful node which is present in the other end of the network. In this paper, we have proposed an algorithm which detects and avoids the wormhole attack while data transfer. In AOMDV,one mechanism is used, which is based on the total round trip time (RTT) of current route and the average round trip times. This mechanism works for both mobile ad hoc networks and wireless ad hoc network. LOLS and AOMDV is going to hold the quality of LOLS of loop free forwarding even with wormhole attack
