Article Title: Routing Security in Mobile Ad Hoc Networks: An Extension of DSR
by Md. Mashud Rana, Alimuzzaman Khan and Syeda Suhana Rahman

An ad hoc network consists of a set of mobile nodes that carry out basic networking functions like packet forwarding, routing, and service discovery without the help of an established infrastructure. Nodes of an ad hoc network rely on one another for forwarding a packet to its destination due to the limited transmission range of each mobile node. The Dynamic Source Routing (DSR) protocol is one the protocols that help to create and maintain routes in an ad-hoc network in spite of dynamic topology. The accurate execution of this protocol requires sustained caring behavior by all nodes participating in the network. However, this behavior may not always be observed and a number of known attacks against the standard DSR protocol can lead to its incorrect execution and even failure. In this paper we present a novel approach of discovering and maintaining dependable routes in an ad hoc network in the presence of various security threats such as spoofing, packet modification on the basis of duplicate route request, acknowledgement, and trust value calculation. Our proposed scheme can adapt quickly over variety of environmental conditions such as highly mobile network topology and high host density.
