Abstract-The subject of Call Admission Control (CAC) for wireless networks has been studied extensively in the literature. Another subject on which many researchers have focused their attention is that of video traffic modeling. However, user mobility, combined with the rapidly growing number of "greedy" multimedia applications, in terms of bandwidth and Quality of Service (QoS) requirements, form a challenging and yet unresolved problem for third and fourth-generation wireless networks. In recent work, we have built a Discrete Autoregressive (DAR (1)) model to capture the behavior of multiplexed H.263 videoconference movies from variable bit rate (VBR) coders. Based on this model, we propose in this work a new efficient CAC scheme for wireless cellular networks, which differs from the existing proposals in the literature in that it uses precomputed traffic scenarios combined with online simulation for its decision making. Our scheme is shown, via an extensive simulation study comparison and a conceptual comparison with well-known existing approaches, to clearly excel in terms of QoS provisioning to users receiving videoconference and Web traffic. To the best of our knowledge, this is the first work in the relevant literature where such an approach has been proposed.

“…That is, the load threshold is further decreased by a guard factor for new calls. This strategy was suggested by (Cheng & Zhuang, 2002;Kulavaratharasah & Aghvami, 1999). In contrast, with the EP policy, both handoff and new calls are accepted if enough capacity exists to accomodate thier needs, no portion of the capacity is restricted for access of either type of call.…”

“…In (Him & Koo, 2005), the call attempts of new and handoff voice/data calls are blocked if there is no channel available, and a soft handoff blocking probability is derived as well. In what concerns the admission policies of handoff calls with respect to new calls, some schemes, such as the ones proposed in (Cheng & Zhuang, 2002;Kulavaratharasah & Aghvami, 1999), deploy a guard channel to reserve a fixed percentage of the BS's capacity for handoff users. Other schemes, called nonprioritized schemes in (Chang & Chen, 2006;Das et al, 2000), handle handoff calls exactly the same way they do with the new calls.…”

Abstract-Call admission control (CAC) plays a significant role in providing the desired quality of service in wireless networks. Many CAC schemes have been proposed. Analytical results for some performance metrics such as call blocking probabilities are obtained under some specific assumptions. It is observed, however, that due to the mobility, some assumptions may not be valid, which is the case when the average values of channel holding times for new calls and handoff calls are not equal. In this paper, we reexamine some of the analytical results for call blocking probabilities for some call admission control schemes under more general assumptions and provide some easier-to-compute approximate formulas.
