A distributed MAC design for data collision-free wireless USB home networks

A Cross-layer Link Adaptive HD Video Transmission Scheme in WiMedia D-MAC based UWB Systems

“…Although it can achieve a high transmission rate, it has many technical problems such as signal attenuation with increasing propagation distance and LOS dependency of signal quality [12]. Therefore, we need to randomly distributed in the network area [6,7].…”

“…Thus, in order to get full benefits of the distributed MAC approach, we have to guarantee the detection of beacon and overcome the resource reservation conflicts among devices. There have been prevention and resolution methods for the DRP reservation conflicts among the WiMedia D-MAC devices in [6,7]. These schemes take multi-hop range DRP conflicts due to mobile hidden node problem into account and show improvement of throughput performance.…”

“…However, these methods do not consider QoS requirement of each traffic stream and only try to prevent and/or resolve MAC-level conflicts in a fixed link without considering another link which can provide more stable data service. Therefore, the algorithms in [6,7] cannot use wireless resources efficiently and may not meet the QoS requirement even with the conflict-resolved link.…”

Wearable Computer Network Design using Dual-Role WUSB Clustering

“…WUSB can be applied to wireless personal area networks (WPAN) applications as well as wired USB applications such as PAN. Because WUSB specifications have defined high-speed connections between a WUSB host and WUSB devices for compatibility with USB 2.0 specifications, the wired USB applications are serviced directly [2][3][4][5][6].…”

A Multimedia Streaming Scheme for N-Screen Services in Wearable Sensor-Based Systems for Health Monitoring

“…Wearable computer systems use the wireless universal serial bus (WUSB) that refers to USB technology that is merged with WiMedia Distributed MAC (D-MAC) technical specifications [3][4][5]. WUSB can be applied to wireless personal area networks (WPAN) applications as well as wired USB applications such as PAN.…”
