A Survey on Secure Routing Protocol for Data Transmission in ad hoc Networks

Abstract

A routing protocol specifies how routers communicate with each other, disseminating information that enables them to select routes between any two nodes on a computer network. A routing protocol shares this information first among immediate neighbors, and then throughout the network. This way, routers gain knowledge of the topology of the network. Mobile ad hoc network (MANET) is an autonomous system of mobile nodes connected by wireless links. Each node operates not only as an end system, but also as a router to forward packets. The nodes are free to move about and organize themselves into a network. These nodes change position frequently. An ad hoc network can change locations and configure itself on the fly. Attacking the routing process can result in a crash of router or a severe degradation of service. Securing these routers in ad hoc Networks is a big issue. This paper surveys some of the techniques that how to secure the MANET followed by the methods to enhance the security level. This paper also discusses about the different protocols used to secure the ad hoc networks.
