Ultra wide band (UWB) is a promising technology for short-range wireless networks. In this paper we present our efforts on investigating the impact of the multipath delay spread on the MAC layer performance of time-hopped impulse-based UWB ad hoc networks. We discuss a simplified channel model for the multipath delay spread and we simulate a single-band MAC protocol which employs binary pulse position modulation. Our simulation results demonstrate that the performance is determined by the properties of the time hopping sequences of the nodes. We observe that the right parameter values depend on the number of nodes deployed, and the delay spread experienced. If the topology changes dynamically, adaptive strategies for varying system parameters are required for achieving the best performance. |
