Abstract

Ultra-wideband wireless (UWB) can provide the physical layer for high capacity personal area networks. When UWB is used for communication between many nodes, relatively long acquisition times are needed when dropping and re-establishing wireless links between the nodes. This paper describes the development and use of mathematical and simulation models to investigate the impact on average packet delay of dropping and reacquiring links between nodes to directly transmit packets versus simply forwarding packets through intervening nodes without breaking the established wireless links. The work presented here assumes that no specific MAC layer protocol, such as WiMedia UWB MAC, is operating. The paper describes the models, explains the selection of modeling parameters used, compares the average packet delay for a network of three simple UWB nodes, and explains the use of these results for network design engineers.
