Performance Analysis of Delayed Acknowledgment Scheme in UWB-Based High-Rate WPAN

H. Chen, Z. Guo, R. Yao, X. Shen, Y. Li
2006 IEEE Transactions on Vehicular Technology  
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 [3] as the PHY technology and IEEE 802.15.3 [1] as the medium access control (MAC) layer support.  ...

Performance Evaluation of Multihop WPANs Based on a Realistic OFDM UWB Physical Layer

Hongju Gao, David G. Daut
2007 2007 IEEE 65th Vehicular Technology Conference - VTC2007-Spring  
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.  ...
