A Call Admission Control Algorithm Based on Stochastic Performance Bound for Wireless Networks

Abstract

In this paper, we derive stochastic performance bounds under the assumption of exponentially bounded burstiness (EBB) traffic model and exponentially bounded fluctuation (EBF) channel model. Then we propose a measurement-based call admission algorithm providing statistical service level agreement (SLA) guarantee for accepted flows based on the QoS prediction equations for both single and multiple priority services. Our call admission control algorithm is characterized by tunable tradeoff between channel utilization and SLA violation probability.

A Call Admission Control Algorithm for Long-Lived and Short-Lived Streaming Media

“…The most common CAC algorithm design approaches used for streaming media servers have included utilization-based [1], measurement-based [2], and delay bound-based [3]. Nonetheless, many CAC algorithms adopted in Internet are hybrid [4]. Besides, almost all existing CAC algorithms regard each stream as long-lived; that is, the lifetime of a stream is not considered.…”
