Abstract :
In this paper, we propose a call admission control (CAC) scheme for wireless cellular networks supporting self-similar data traffic, which is rarely discussed in previous literature. The grade of service (GoS) at the call level is represented by handoff call dropping probability, while the quality of service (QoS) at the packet level is represented by transmission accuracy and delay. The effective bandwidth for the data traffic is derived to support the QoS requirements. The user and call transition functions are derived to compute the handoff call dropping probability. The proposed CAC scheme is to ensure satisfaction of both QoS and GoS, and to achieve maximal resource utilization.
