Call admission control schemes: a review

H.G. Perros, K.M. Elsayed
1996 IEEE Communications Magazine  
In ATM-based B-ISDN, congestion control should support a set of ATM quality of service classes su cient for all foreseeable B-ISDN services.  ...  For instance, CBR and VBR services use preventive schemes and ABR service is based on a reactive scheme. Preventive congestion control involves the following two procedures: call admission control  ...  Can the switch provide the quality-of-service requested by the new connection?  ...

Call Admission and Handover in Heterogeneous Wireless Networks

Ken Murray, Dirk Pesch
2007 IEEE Internet Computing  
Today's mobile communication networks support not just simple mobile voice and data services but also access to mobile Internet-based services with varying bandwidth and quality-of-service requirements  ...  An increasing demand for wireless access to packet-based services has, in turn, driven the need for call admission and intersystem handover control strategies to make network roaming more seamless.  ...  Acknowledgments The Higher Education Authority of Ireland funded this work under the HEA PRTLI III M-Zones Project.  ...

A Scalable Call Admission Control Algorithm

Z. Ali, W. Sheikh, E.K.P. Chong, A. Ghafoor
2008 IEEE/ACM Transactions on Networking  
In this paper we propose a scalable algorithm for connection admission control (CAC). The algorithm applies to a Multiprotocol Label Switching (MPLS) ATM switch with a FIFO buffer.  ...  The sources may be heterogeneous both in terms of their statistical characteristics (peak cell rate, sustained cell rate, and burst size attributes) as well as their Quality of Service (QoS) requirements  ...  Furthermore, a new connection is admitted only if the aggregate ECR value of the already admitted calls and the new connection does not exceed the link capacity.  ...

Call admission control with opportunistic scheduling scheme

Mehrdad Dianati, Rahim Tafazolli, Xuemin (Sherman) Shen, Kshirasagar Naik
2009 Wireless Communications and Mobile Computing  
Index Terms Call admission control, opportunistic scheduling, quality of service.  ...  The proposed admission scheme maintains minimum average rates of the admitted users, i.e., new users will be admitted if the base station has enough resources to support the required minimum average transmission  ...  Acknowledgement This work has been partially supported by a research grant from Bell Canada and the Natural Sciences and Engineering Research Council (NSERC) of Canada.  ...

Call Admission Control Using Neural Network and SVM

Poonam Sanap
2016 IJARCCE  
Call Admission Control is a provisioning strategy used to limit the number of call connections into the networks in order to reduce the network congestion and provide the desired Quality of Service (QoS  ...  To overcome the problems arises due to traditional CAC schemes we propose a new CAC using hybrid technique i.e. SVM and Neural network.  ...  I am very much thankful to our H.O.D and also guide Prof. G. A. Kulkarni of the Department of Electronics & Communication Engineering For their valuable suggestions and helping attitude.  ...

Call admission control in wireless networks: a comprehensive survey

M.H. Ahmed
2005 IEEE Communications Surveys and Tutorials  
Arriving (new and handoff) calls are granted/denied access to the network by the call admission scheme (CAC) based on predefined criteria, taking the network loading conditions into consideration.  ...  Radio resource management (RRM) plays a major role in Quality of Service (QoS) provisioning for wireless communication systems.  ...  When a new call arrives, the effective bandwidth of all existing users, including the new call (using the highest quality level), is determined.  ...
