Modification of DSR and its implementation in Ad Hoc City

Few real-world applications of mobile ad hoc networks have been developed or deployed outside the military environment, and no traces of actual node movement in a real ad hoc network have been available. In this paper we proposed a security scheme for an Ad Hoc City. We have designed an algorithm and corresponding packet structures to secure the pure ad hoc portion of the architecture. In order to achieve our goal, we have modified the Dynamic Source Routing Protocol (DSR) to adapt it in the environment under consideration. The Dynamic Source Routing protocol (DSR) is a simple and efficient routing protocol designed specifically for use in multi-hop wireless ad hoc networks of mobile nodes. DSR allows the network to be completely self-organizing and self-configuring, without the need for any existing network infrastructure or administration. The protocol is composed of the two mechanisms of Route Discovery and Route Maintenance. We have modified the Route Discovery and Route Maintenance phase in order to provide more security features.
