Fast and Accurate Cooperative Tracking in Wireless Networks
IEEE Transactions on Mobile Computing
By Thuraiappah Sathyan,Mark Hedley
Issue Date:September 2013
The utility of wireless networks for many applications is increased if the locations of the nodes in the network can be tracked based on the measurements between communicating nodes. Many applications, such as tracking fire fighters in large buildings, req...
WLAN Location Service with TXOP
IEEE Transactions on Computers
By Ren Ping Liu,Mark Hedley,Xun Yang
Issue Date:March 2013
The provision of location-based services with high positional accuracy requires the use of Time of Arrival (TOA)-based techniques. However, existing TOA-based WLAN location service schemes are inefficient due to the individual query and response ranging me...
Accurate Wireless Localization in Sports
By Mark Hedley,Jian Zhang
Issue Date:October 2012
The wireless ad hoc system for positioning (WASP) provides high accuracy and high update rates when used for performance monitoring in elite sports training, where using real-time location and physiological information helps improve athletic performance.
Selective Detection for MIMO-OFDM Transmission
Wireless Broadband and Ultra Wideband Communications, International Conference on
By Hajime Suzuki, Iain B. Collings, George Lam, Mark Hedley
Issue Date:August 2007
We present a novel technique for the detection of spatially multiplexed transmitted symbols in uncoded multiple-input multiple-output orthogonal frequency division multi-plexing (MIMO-OFDM) system. The method, termed Selective Detection, observes errors ca...
New Statistical Model for VBR Video Traffic in ATM Networks
Computer Communications and Networks, International Conference on
By Gajendra S. Sisodia, Dr. Mark Hedley, Dr. Ling Guan, Subrata De
Issue Date:October 1998
In this paper, we present a new approach to modelling variable bit rate (VBR) coded video sources in asynchronous transfer mode (ATM) networks. Unlike the existing methods which model the number of cells generated by the coder for a sequence of video frame...
