Wireless Adhoc Networks in the Metropolitan/Wide Area: Concepts and First Results

– This paper is dedicated to on-going research activities in the field of wireless metropolitan and wide area networks with Quality-of-Service (QoS) guarantees. We focus on self-organizing systems, so-called adhoc networks, which can operate without any wired infrastructure (e.g. cellular base stations) – except for some interface points providing interconnectivity to other networks like the Public Switched Telephone Network (PSTN) or the Internet. Obviously, the lack of a wired back-bone network implicates that routing, signalling and other management functions must be handled completely over the air in a self-organizing manner.
