Abstract

In this paper, we first present the challenges involved in the design of media access control (MAC) protocols for UWB based wireless networks. We formulate the radio resource allocation problem as a theoretical optimization problem that maximizes the system throughput under different constraints that reflect the UWB physical layer, the system topology as well as the traffic patterns. We introduce a sub-optimal practical MAC protocol that allocates the nodes' transmission power and bit rates. In the proposed method, we differentiate between two different classes. best effort and real-time classes. We implemented our scheme in MATLAB and the simulation results show that the proposed method results in significant higher throughput compared to a random access MAC protocol.
