Performance analysis of the threshold CAC strategy for multimedia traffic in wireless networks
Derviş Z. Deniz, Nagla O. Mohamed · 2004
Performance modeling and evaluation of the threshold call admission control (CAC) strategy in a wireless cell serving two types of customers; narrowband (n-type) customers whish require 1 channel and wideband (w-type) customers which require b/sup w/ /spl ges/ 1 channels is performed. The steady state probabilities, p(K) of the system for the threshold CAC strategy are computed using a modified matrix algorithmic technique. The results show that the handoff call loss probabilities can be made as small as possible with the use of appropriate threshold values for the new call attempts.
