N1 - Funding Information:
Yang Yang received the B.Eng. and M.Eng. degrees in Radio Engineering from Southeast University, Nanjing, PR China, in 1996 and 1999, respectively; and the Ph.D. degree in Information Engineering from The Chinese University of Hong Kong in 2002. He is currently a Lecturer with the Department of Electronic and Electrical Engineering at University College London (UCL), United Kingdom. Prior to that, he served the Department of Information Engineering at The Chinese University of Hong Kong as an Assistant Professor from August 2002 to August 2003, and the Department of Electronic and Computer Engineering at Brunel University, United Kingdom, as a Lecturer from September 2003 to February 2005. His general research interests include mobile ad hoc networks, wireless sensor networks, wireless mesh networks, third generation (3G) mobile communication systems and beyond, mobile IPv6, dynamic radio resource management (RRM) for integrated services, cross-layer performance evaluation and optimisation, and medium access control (MAC) protocols. He is a member of the IET, IEEE and ACM. Yang has served more than 25 international conferences as TPC member, session chair and symposium chair. Currently, he is on the Editorial Board of Journal of Wireless Communications and Mobile Computing (Wiley), a guest editor for Computer Communications (Elsevier) and IEEE Network Magazine. He was the IEEE Standards Coordinator for Region 8 (Europe, Africa and Middle East) and currently is the Chair of GOLD affinity group at the IEEE United Kingdom and Republic of Ireland Section. Yang received the Young Scientist Award from the Hong Kong Institution of Science in 2003, the Short-Term Research Fellowship from British Telecom in 2004, and was a Visiting Scholar at University of Waterloo, Canada, in summer 2005.

N2 - In wireless ad hoc networks, the major quality of service (QoS) concern and challenge in the design and analysis of contention-based medium access control (MAC) protocols is to achieve good throughput and access delay performance in the presence of hidden terminals, which are defined as the terminals out of the radio coverage area of an intended transmitter but within that of the receiver. We propose and analyze in this paper a new dual-channel random access protocol, called "Double Sense Multiple Access" (DSMA), for improving QoS support in wireless ad hoc networks. By separating the transmissions of ready-to-send (RTS) and data packets into two time-slotted channels and by introducing a novel double sense mechanism, DSMA completely solves the hidden terminal problem and can guarantee the success transmission of data packets. By taking into account the most complex network scenario in which all transmitters are hidden terminals with respect to each other, key QoS metrics such as throughput, blocking probability and access delay are derived mathematically for the proposed DSMA protocol. These analytical results are verified by extensive computer simulations.
