A NOVEL TECHNIQUE FOR DEFENDING ROUTING ATTACKS IN OLSR MANET
M. Mohana Priya · 2010
MANET (Mobile Adhoc Networks) refers to network designed for special application for which it is difficult to use a backbone network. In MANET, applications are involved with sensitive and secret information. Since the MANET assumes a trusted environment for routing, security is major issue. In this paper we analyze the vulnerabilities of a pro-active routing protocol called OLSR (Optimized link state routing) in MANET. We investigate the various routing attacks that can be launched in OLSR. Analyzing the attack, we propose a mechanism to secure the OLSR protocol from specific routing attack known as node isolation attack.
