Communication in ad hoc networks traditionally relies on network addresses known a priori. This paper addresses the need for application-aware adaptive communication that creates network routes based on applications' dynamic resource requests. The paper motivates this need by examining the state of the art in mobile ad hoc network communication, the requirements of applications, and the impact of existing protocols on flexibility and efficiency and introduces an intuitive generalization to source routing which facilitates discovery of a resource in an ad hoc network and the creation and maintenance of a route from the requesting host to the discovered destination.
