Abstract

In this work, we first introduce a new traffic model for medium quality MPEG-4 videoconference traffic and then proceed to use it in the implementation of a new Call Admission Control scheme. Our scheme makes decisions on the acceptance/rejection of a new video call not only based on the predicted capacity that users will consume, but also on the possible revenue gained for the provider when degrading current users in order to accommodate new ones. Via an extensive simulation study our scheme is shown to provide excellent Quality of Service (QoS) to wireless videoconference users.
