Abstract :
Bandwidth Allocation Schemes (BAS) and Call Admission Control (CAC) algorithms for a multi-services wireless cellular network must guarantee the potentially different Quality of Service (QoS) requirement from diversified applications, meanwhile ensuring the scarce bandwidth be utilized efficiently. A growing wireless multimedia application area is mobile video-phone and its variations such as mobile teleconference. We propose a new Bandwidth Allocation Scheme (BAS) and corresponding CAC algorithms called Call Admission Control for Voice&Video (CACV2) which is appropriate to wireless multimedia applications. Specifically, we employ a modified Markov model -- "triangular" two-dimensional Markov chain model to analyze our BAS. The simulation results show that our proposed algorithms outperform other schemes that employ assigning requested channels as a whole to incoming calls containing video requests.
