In the next generation cellular communication environment, the effective delivery of multimedia traffic will become an increasingly important issue. In multimedia cellular networks, we should not only minimize handoff dropping probability, but also control new call blocking probability and utilize bandwidth efficiently. In this paper, a novel preemptive time-threshold based bandwidth allocation scheme(PTTS)...
In this paper, we propose a scheme for improved performance of resource reservation and call admission control for cellular networks called Predictive User Mobility Behavior (PUMB) scheme. This algorithm is proposed in which bandwidth is allocated more efficiently to neighboring cells by key mobility parameters in order to provide Quality of Service (QoS) guarantees for transferring traffic. The cell...
A new variable bandwidth scheme (VBS) for channel resources predictive control and call admission control in cellular networks is presented in the paper. VBS mainly aims to the QoS enhancement of cellular networks. Compared with the time-based channel predictive control (TCPC) schemes, VBS has a good performance in call dropping probability (CDP) and call blocking probability (CBP). Moreover, considering...
This paper proposes a novel adaptive time- threshold based bandwidth allocation scheme (ATTS) for voice handoff calls in cellular wireless networks. The proposed scheme overcomes the flaws of the fixed time-threshold based bandwidth allocation scheme (FTTS) in the total admitted traffic and the blocking probability of new calls. In proposed scheme, bandwidth threshold for non-prioritized handoff calls...
