“…In this type of scheme, calls are accepted whenever there are free channels. Depending on the approach, new calls are blocked and handoff calls are queued [21], vice versa [22], or all calls are queued and the queue is rearranged based on certain priorities [23]. The work presented in this paper falls conceptually within the second category, that is, of the QP schemes, as in our CAC scheme, both handoff calls and the new calls originating from within the picocell are accepted if enough free channel bandwidth exists to accommodate them, and no portion of the bandwidth is restricted for access of either type of call (therefore, our scheme is conceptually similar to [23]).…”

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.

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.

“…When no idle channels are accessible, calls may be queued or blocked (i.e cleared from the system). Queueing priority schemes can be divided into three groups: new call queuing schemes (Chang et al, 1999), handover call queuing schemes (Yoon & Kwan, 1993); (Tian & Ji, 2001); (Agrawal et al, 1996), and all calls queuing schemes (Yoon & Kwan, 1993); (Chang et al, 1999).…”
