Multimedia transport in multihop dynamic packet radio networks

The paper presents a distributed architecture which relies on code division access scheme for multimedia transport in a wireless mobile radio network without a fixed infrastructure. The proposed multicluster architecture has the capability of rapid deployment and dynamic reconfiguration. Without the need of base stations, this architecture can operate in areas without a wired back-bone infrastructure. The presented architecture has two main advantages. First, this architecture can provide spatial reuse of the bandwidth due to node clustering. Second, computer simulation reveals that our cluster structure is robust in the face of topological changes due to node motion, node failure, and/or new node addition. In all, this architecture provides a stable infrastructure for the integration of different types of traffic in a dynamic radio network.
