Certified Wireless Universal Serial Bus (WUSB) is one of different varieties of Wimedia standard for distributed medium access control (MAC) protocol for ultra wide band (UWB) communications in the wireless personal area network (WPAN). To the best of our knowledge, no technical contributions exist in the open literature at present simulating WUSB and its performance. In this paper, we investigated...
In this paper, a dynamic MAS reallocation method is proposed for the WiMedia MAC. WiMedia MAC configures a fully distributed network. WiMedia devices communicate during Superframe which is a communication unit in WiMedia MAC. guarantee QoS, WiMedia MAC uses a TDMA based time slot reservation protocol named distributed reservation protocol (DRP). On existing WiMedia networks, if any conflict occurs...
Quality of service (QoS) provisioning is one of the most important criteria in newly emerging UWB WPANs, as they are expected to support a wide variety of applications from time-constrained, multimedia streaming to throughput-hungry, content transfer applications. Recently, the WiMedia Alliance has announced the PHY/MAC specification together with the common radio platform for UWB WPANs. The WiMedia...
A distributed medium access control (D-MAC) protocol has been proposed to support high-rate wireless personal area networks (HR-WPANs) by the WiMedia Alliance. The WiMedia D-MAC solves the problems of the IEEE 802.15.3 MAC caused its centralized architecture. However, due to mobility of WiMedia devices in multi-hop environment, DRP (distributed reservation protocol) reservation conflicts happen frequently...
An analytical formulation of the saturated delay of prioritized contention access (PCA) in the presence of hard distributed reservation protocols (DRPs) and beacon period (BP) in WiMedia MAC is presented The analytical framework is formulated for one Hard DRP class and N PCA classes. The state transition diagram for the ith priority PCA class is modeled by a tridimensional discrete-time Markov chain...
Next generation wireless personal area networks (WPAN) are intended for a variety of applications. The Multiband OFDM Alliance (MBOA) is currently developing a new physical layer (PHY) and medium access control (MAC) protocol, which fit the needs of this mass market. The MBOA standards provide wireless technology offering data rates of up to 480 Mbit/s. Besides support for quality of service (QoS),...
