Abstract

A new design of the optimal MAC frame payload length for maximizing the saturation throughput of the Prioritized Contention Access (PCA) of the WiMedia Ultra Wideband (UWB) standard in Rayleigh fading channel is presented in this paper. In the WiMedia standard, the Multiband Orthogonal Frequency Division Multiplexing (MB-OFDM) is used as the basic physical scheme. The proposed design is based on the throughput analysis carried out by extending an original Enhanced Distributed Contention Access (EDCA) model for 802.11e into the MB-OFDM UWB protocol. The extended model considers the effects of the bit error rate, the transmission opportunity limits, and the uniqueness of WiMedia MAC timing structure. The station throughput is sensitive to the frame payload length, and the optimal frame payload length increases exponentially when the value of the signal-to-noise ratio is higher. The optimal payload length is independent of the number of the active stations, data rate, and the priority of the Access Categories (ACs). Therefore, a station can dynamically adapt the length of the transmitted frame in the MAC layer according to the current SNR level so as to maximize its saturation throughput in the MB-OFDM UWB network.
