PROJECT TITLE :

Mitigating Denial of Service Attacks in OLSR Protocol Using Fictitious Nodes

ABSTRACT:

With the main focus of analysis in routing protocols for Mobile Ad-Hoc Networks (MANET) geared towards routing efficiency, the resulting protocols have a tendency to be prone to various attacks. Over the years, emphasis has conjointly been placed on improving the safety of these networks. Completely different solutions have been proposed for various varieties of attacks, however, these solutions usually compromise routing potency or network overload. One major DOS attack against the Optimized Link State Routing protocol (OLSR) known as the node isolation attack happens when topological information of the network is exploited by an attacker who is ready to isolate the victim from the remainder of the network and subsequently deny Communication services to the victim. In this paper, we have a tendency to recommend a unique answer to defend the OLSR protocol from node isolation attack by employing the identical tactics employed by the attack itself. Through intensive experimentation, we tend to demonstrate that 1) the proposed protection prevents a lot of than 95 percent of attacks, and a couple of) the overhead needed drastically decreases as the network size will increase till it's non-discernable. Last, we have a tendency to recommend that this sort of solution can be extended to different similar DOS attacks on OLSR.
