CO-CAC: A new approach to Call Admission Control for VoIP in 5G/WiFi UAV-based relay networks
Computer Communications, 2023 Voice over IP (VoIP) requires a Call Admission Control (CAC) mechanism in WiFi networks to preserve VoIP packet flows from excessive network delay or packet loss. Ideally, this mechanism should be integrated with the operational scenario, guarantee the quality of service of active calls, and maximize the number of concurrent calls.

Computationally Efficient Dynamic Code Assignment Schemes With Call Admission Control (DCA-CAC) for OVSF-CDMA Systems [PDF]
IEEE Transactions on Vehicular Technology, 2008 This paper investigates computationally efficient suboptimal dynamic code assignment (DCA) schemes with call admission control (CAC) for orthogonal variable spreading factor code-division multiple-access systems. We examine two different approaches. The first approach reduces the complexity of the DCA scheme by partitioning the total resource (either ...

QoS Improvement Analysis Call Admission Control(CAC) Algorithm based on 3GPP PBNM [PDF]
The Journal of the Korea Contents Association, 2012 In this paper, to provide various services of QoS, and moreover applying traffic ratio to CAC(Call Admission Control) algorithm tested how long average data rate and the average packet delay time. When CAC algorithm is not applied, traffic mixture ratio is 1:1:4:4, the FTP Service 0.4, web services 0.6, streaming service 0.7, the packet delay ...

Performance of a Two-Level Call Admission Control Scheme for DS-CDMA Wireless Networks
EURASIP Journal on Wireless Communications and Networking, 2007 We propose a two-level call admission control (CAC) scheme for direct sequence code division multiple access (DS-CDMA) wireless networks supporting multimedia traffic and evaluate its performance. The first-level admission control assigns higher priority

Models for Call Acceptance Based on Handoff Guarantees
EURASIP Journal on Wireless Communications and Networking, 2008 Call admission control (CAC) is important for cellular wireless networks to provide quality-of-service (QoS) requirements to users. Static and adaptive CAC schemes, respectively, make unrealistic assumptions about the distributions of the handoff call ...
