Abstract: While bandwidth management in cellular communication systems has been thoroughly examined for voice channel admission by developing several DCA (Dynamic Channel Assignment) strategies, there are a few only efforts investigating assignment and management of multimedia enabling channels in wireless communications. However, the increasing demand for these advanced services in cellular networks such as data, MMS and video transfers raises the problem of efficient bandwidth management in terms of channel assignment meeting QoS criteria. Several algorithms for supporting QoS services have been presented in the literature based mainly on bandwidth reservation and capacity management for enabling efficient handoff over cellular networks. The goal of this paper is to develop and investigate, however, novel integral DCA algorithms for supporting data (e.g. files) and video (video viewing, video conference) transmission with Quality of Service (QoS), and their evaluation thro!
ugh a prototype advanced statistical simulation environment for cellular communications. Moreover, we analyze the dynamic and distributed channel allocation strategies for enabling advanced multimedia services based on signal purity measures and interference measurements. Finally, the performance of these suggested algorithms evaluated through a proposed prototype simulation environment is discussed.
