Mobile Ad Hoc Networks (MANETs) Routing Protocols

In this paper, the authors describe the security issues in Mobile Ad Hoc networks. A malicious attack by nodes in networks significantly affects the Quality of Service delivered by the network and disrupts the route discovery process. This problem is especially serious in Mobile Ad Hoc NETworks (MANETs) as traditional methods created to prevent such attacks on wired networks are only partially successful when applied to mobile networks. The authors present some techniques to secure Mobile Ad Hoc Networks from these attacks. They take AODV as an example and develop a security mechanism to protect its routing information.
