Abstract


Ad-hoc networking is a concept in computer communications, which means to communicate with each other form a temporary network, without any form of centralized administration. Each node participating in the network acts both as host and a router and must therefore be willing to forward packets for other nodes. For this purpose, a routing protocol is needed. In mobile ad-hoc network (MANET), secure routing is a challenging issue due to its open nature, infrastructure less property and mobility of nodes. Many mobile ad-hoc network routing schemes have been proposed, but none of them have been designed with security as a goal. Currently the mobile wireless technology is experiencing rapid growth. However the major challenge for deployment of this technology with its special characteristics is securing the existing and future vulnerabilities. The lack of static infrastructure causes several issues in mobile ad hoc network (MANET) environment, such as node authentication and secure routing. In this paper, we propose a new protocol for secure routing of data packets in MANET. The approach is very simple, which will reduce the computational overhead to a lot extent. We propose security goals for routing in mobile ad-hoc networks, an approach significantly different from the existing ones, the heart of the protocol is a specific criterion of the nodes called fidelity. The approach will reduce the computational overhead to a lot extent. We first explain what fidelity is and give a comprehensively detailed description of the protocol.
