Call Admission Control for QoS Provisioning in Multimedia Wireless ATM Networks

概要
- 論文の詳細を見る
In this paper, we investigate a call admission control (CAC) problem in a multimedia wireless ATM network that supports various multimedia applications based on micro/pico cellular architectures. Due to reduced wireless cell size (compared to conventional cellular networks), forced termination of calls in progress becomes a more serious problem in the wireless ATM network. Another problem specific to the multimedia wire-less network is how to avoid an excessive delay of non-realtime applications under the presence of various realtime applications with priority over non-realtime applications. We consider two service classes; CBR for realtime applications and UBR for non-realtime applications, and then propose a new CAC scheme that addresses above two problems while minimizing a blocking probability of newly arriving calls of CBR. Through the analytical methods, we derive the blocking probabllities and forced termination probabilities of CBR calls and the average packet delay of UBR connections. We also present a method that decides the optimal CA, threshold values in our CAC scheme.
