Executive Summary

This paper describes a self-organizing, multi-hop, mobile radio network, which relies on a code division access scheme for multimedia support. In the proposed network architecture, nodes are organized into non-overlapping clusters. The clusters are independently controlled and are dynamically reconfigured as nodes move. This network architecture has three main advantages. First, it provides spatial reuse of the bandwidth due to node clustering. Secondly, bandwidth can be shared or reserved in a controlled fashion in each cluster. Finally, the cluster algorithm is robust in the face of topological changes caused by node motion, node failure and node insertion/ removal.
