Abstract
For those driven by the idea of integrating all services, such as voice, data, video, and multimedia into the wireless domain, related topics have been on the horizon. A novel random early blocking with engineered threshold (REB-ET) CAC scheme, taking account of the concept of virtual partitioning as well as acceptance probability, is proposed to achieve high resource utilization as well as maintain the blocking probability at an acceptable level in wireless multimedia network with conversational, streaming and background services. An analytical method is developed to calculate performance measures of interest, i.e., new call blocking probability and forced termination probability for conversational and streaming services, average available bandwidth for streaming services, and average packet delay for background services. It is shown that analytical results are close to the simulation results. Also, numerical results under not only stationary but also nonstationary scenario are shown to illustrate the robustness of the proposed scheme.
