Abstract: Ultra-wideband (UWB) communication has recently emerged as a technology that offers high data rate services for future wireless personal area networks. Due to its high bandwidth, it is substantial effort to design medium access control (MAC) protocols that perfectly utilise the available shared bandwidth offered by UWB technology. This paper introduces an extensive 4-dimensional finite Markov chain queueing model to investigate the performance of a multi-band protocol that was proposed in literature in terms of system occupancy, waiting time, throughput, packet loss and blocking probabilities. Our motivation is to precisely estimate packets collision probability due to randomly selection of receivers or bands. Besides introducing the finite buffer, our queuing model reflects the system behaviour in-depth. Next, we validate the obtained analytic results using discrete-event simulation. Finally, we introduce an outline of a proposal to eliminate the randomness of selecting receivers and bands.
