Congestion control policies for wireless multimedia CDMA networks
Abstract
The issues of integrating multimedia traffic in the reverse (mobile to base station) link of wireless CDMA networks are studied. Due to their delay constraint, realtime (voice/video) services are subject to connection-level admission control. In order to maintain the quality of realtime voice/video traffic while fully utilizing the unused channel capacity, non-realtime data traffic follows burst-level congestion control. Two congestion control policies are introduced and their performance under 3 types of feedback information is compared. The impact of various system parameters, such as the traffic parameters (especially video) and the processing gain of the CDMA system are also quantified.
