Ad Hoc On-demand Secure Source Routing

In mobile ad hoc networks, nodes do not rely on any routing infrastructure but the nodes route messages for each other. This communication set up functions properly only when the participating nodes co-operate with each other in routing and forwarding. It may, however, be advantageous for some nodes not to co-operate (e.g, to save power or get more bandwidth or to launch security attacks). This paper describes a routing protocol that is secure against attacks and uses some minimal trust levels amongst participating nodes. The set up uses source routing and no route caches are used. The idea is to route data on routes that are secure but may not be the shortest routes
