摘要：WiMedia standardized a fully distributed high data rate communication using ultra wideband (UWB) for wireless personal area networks (WPANs). WiMedia Medium Access Control (MAC) provides a synchronous data communication service by Prioritized Channel Access (PCA) and isochronous service by Distributed Reservation Protocol (DRP). In this paper we propose three different approaches to analyze the reservation protocols, PCA and DRP, of WiMediaś MAC. In the first two approaches we kept the portions of the superframe fixed for DRP and PCA traffics while the third approach follows random reservation. To test out the PCA and DRP by proposed approaches we presented a scenario of connected devices and incoming devices with mix traffic (video, VoIP and best effort). By means of simulations using Omnet++ and analytical results, we demonstrate that the network offers maximum throughput as well as minimum blocking and energy consumption when using the third approach, provides access to medium by Hard, Soft and PCA reservation under the WiMedia rules and policies. The throughput fairness is also estimated for the three approaches using Gini index.
