Bandwidth reservation for real-time traffic in wireless mobile environment Conference Paper uri icon

abstract

  • 1999 IEEE. This paper proposes a new bandwidth reservation strategy (Two Level Guarantee) in wireless environment based on the user mobility specification which is assumed to be given at call set up time. This approach is very useful in that 1) it doesn't use prediction method which might require rather heavy computation, 2) it reserves wireless bandwidth as much as the user requests, 3) it is flexible to control the new call blocking rates and handoff dropping rates with the number of EG (Exclusive Guarantee)s and PG (Pseudo Guarantee)s and threshold values. Simulation results based on random walk model, with dynamic traffic and operating conditions show that a TLG system can admit new calls roughly three times larger than the APR (All Path Reservation) system, and can have roughly 2.5 times larger naturally terminated calls than the APR system.
