CDMA systems have a trade-off relationship between the frame error rate (FER) and the number of accepted users. Therefore, the call admission control (CAC) scheme is essential for guaranteeing the FER below the required value, which is the measure of the quaility of service (QoS) in the frame level. In cellular networks, the dropping probability of handoff calls is another critical measure for ...

With the deployment of packetized wireless networks, the need for Quality of Service is becoming increasingly important. In order for QoS to be implemented and eeciently supported, a number of key areas in wired/wireless integration need to be addressed. One key issue is the call admission policy for the base station sched-uler. In this paper we provide a call admission control policy that is d...

This paper proposes a novel call admission control scheme capable of providing a combination of call and packet level quality of service requirements in cellular packet networks. Specifically, we propose a distributed call admission control scheme called PFG, which maximizes the wireless channel utilization subject to a predetermined bound on the call dropping and packet loss probabilities for ...

In order to meet the Quality-Of-Service (QOS) requirements of the VOD (Video-On-Demand) service, and, on the other hand, to maximize the system throughput (revenue), it is essential that the admission control algorithm be carefully designed. In this paper, two new types of admission control schemes for the VOD service are proposed. They are the Enhanced Strict Admission Control (ESAC) and the P...

In order to provide Quality of Service (QoS) assurances networks perform call admission control before accepting a new connection. Rather than relying on a priori traac descriptors (such as leaky buckets), which often poorly characterize the actual traac, measurement{based admission control bases admission decisions on measurements of the actual traac. In this paper we rst develop a novel Large...
