Abstract

In this paper we study connection admission control CAC in IEEE 80211based ESS mesh networks An analytical model is developed for studying the effects of CAC on mesh network capacity A distributed CAC scheme is proposed which incorporates load balancing when selecting a mesh path for new connections Our results show that connection level performance including both average number of connections and connection blocking probability can be greatly improved using the proposed mechanism compared to other admission control schemesDongmei Zhao received the PhD degree in Electrical and Computer Engineering from the University of Waterloo Waterloo Ontario Canada in June 2002 Since July 2002 she has been with the Department of Electrical and Computer Engineering McMaster University Hamilton Ontario Canada where she is an assistant professor Dr Zhao’s research interests include modeling and performance analysis qualityofservice provisioning access control and admission control in wireless networks Dr Zhao is a member of the IEEEJun Zou received his B Eng and M Eng Degrees from Tianjin University China in 1999 and 2002 respectively He worked at Siemens Communication Networks Ltd Beijing from 2002 to 2004 Currently he is a PhD student at McMaster University Canada His research interests include wireless networking routing protocols architecture of next generation networks and network securityTerence D Todd received the BASc MASc and PhD degrees in Electrical Engineering from the University of Waterloo Waterloo Ontario Canada While at Waterloo Dr Todd spent 3 years as a Research Associate with the Computer Communications Networks Group CCNG He is currently a Professor of Electrical and Computer Engineering at McMaster University in Hamilton Ontario Canada At McMaster he has been the Principal Investigator on a number of projects in the optical networks and wireless networking areasProfessor Todd spent 1991 on research leave in the Distributed Systems Research Department at ATT Bell Laboratories in Murray Hill NJ He also spent JanuaryDecember 1998 on research leave at The Olivetti and Oracle Research Laboratory in Cambridge England While at ORL he worked on the piconet project which was an early embedded wireless network testbed Dr Todd’s research interests include metropolitan/local area networks wireless communications and the performance analysis of computer communication networks and systems Dr Todd is a past Editor of the IEEE/ACM Transactions on Networking and currently holds the NSERC/RIM/CITO Chair on PicoCellular Wireless Internet Access Networks
