Enhancement of Secure Routing Attack Against in Mobile Adhoc Networks

Mobile Adhoc NETworks (MANET) is a collection of wireless nodes that can dynamically form network to exchange information without using any preexisting fixed network infrastructure. The special features of this MANET bring these technology great opportunities together with severe challenges. MANET are known to be vulnerable to a variety of attacks due to lack of central authority or fixed network infrastructure. In many more security schemes have been proposed to identify misbehaving nodes .In intrusion detection techniques developed for weird networks, the basic nature of MANET the authors cannot apply them directly in to mobile networks. They propose and discuss an optimized link state routing protocol named OLSR for mobile wireless networks.
