retransmission schemes such as hybrid automatic repeat request (HARQ) to improve system throughput for an IEEE 802.15.3 compliant system. ... In this paper we study on the one hand under delayedacknowledgement (Dly-ACK) mechanisms the option of using ACK Request to improve system robustness, and on the other hand the incorporation of effective ... Figure 1 . 1 Superframe structure and Dly-ACK format in the IEEE 802.15.3. Figure 2 . 2 Data transmission process for Dly-ACK mechanism. ...doi:10.2528/pier08082601 fatcat:c5yzzjbd6zff7af7sutiajhtoq
As a prominent example of these activities, the IEEE 802.15.3 Task Group (TG) published a standard for high-rate wireless personal area network (HR-WPAN). ... Therefore, in this paper, we propose a novel feedback-assisted channel time allocation method for HR-WPAN. ... Band (UWB) technology for use in the physical (PHY) layer in HR-WPAN. ...doi:10.1007/s11276-009-0191-0 fatcat:lzzy3i26drgzvkmhhlgxgmpohu
The ultra-wideband (UWB) technology is being defined as the physical-layer (PHY) support for the high-rate WPAN. ... At medium access control (MAC) layer of the WPAN, a delayed acknowledgment (Dly-ACK) or burst-ACK (B-ACK) scheme is introduced to improve the channel utilization by reducing the overhead of ACK. ... One is direct sequence UWB (DS-UWB), which utilizes the DS-UWB  as the PHY technology and IEEE 802.15.3  as the medium access control (MAC) layer support. ...doi:10.1109/tvt.2005.863432 fatcat:3fjo6v2g2jdx5pyaihuxw6zevm
is one of the promising candidates for the UWB (Ultra-Wide-Band)-based alternative physical (PHY) layer for WPANs (Wireless Personal Area Networks). ... Hence, the scheme is a good choice for the routing protocol to be used with multihop WPANs based on an OFDM UWB physical layer. ... Three ACK policies are defined in the IEEE 802.15.3 Standard: Imm-ACK, No-ACK,and Dly-ACK. For the Imm-ACK policy, the receiver issues an ACK frame to the transmitter for every received packet. ...doi:10.1109/vetecs.2007.31 dblp:conf/vtc/GaoD07 fatcat:yv5iy5b47rhjbacawn2it2mwbe
In this paper, we propose a rate-adaptive Medium Access Control (MAC) protocol for HR WPAN. ... The specification of High-Rate Wireless Personal Area Network (HR WPAN) has been standardized by the IEEE 802.15.3 Task Group for communications of consumer electronics and portable communication devices ... CONCLUSION In this paper, we propose a rate-adaptive MAC protocol with a constant PHY frame length for HR WPAN. ...doi:10.1109/wcnc.2004.1311646 dblp:conf/wcnc/KimFW04 fatcat:eugl536qz5aa7a2bu2q4lgyyrq
Designed for high rate wireless personal area networks (WPANs), the IEEE 802.15.3 protocol enables peer-to-peer communications between devices (DEVs) with quality of service (QoS) support. ... This thesis presents several performance enhancement methods and scatternet formation techniques for 802.15.3 networks. ...
