Research ArticleOpen accessPhrase in the titleAn Efficient Combined Call Admission Control and Scheduling Algorithm to Improve Quality of Service for Multimedia Services Over Next Generation Wireless NetworksG. Nantha Kumar, A. ArokiasamyWe nominate a weighted service queuing approach, each service queue is allotted a preset priority weight and Call Admission Control scheme for service classes defined in IEEE 802.16 standard. Different group of queues have been implemented to transmit different service classes. Allocation of bandwidth usage of each service classes are relying on maximum data that could take part in connection … …Journal of Computer Science, Vol. 11, Issue 2 · 20 Sep 2014 · 6,488 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleUtility Based Scheduling and Call Admission Control for Long Term Evolution NetworksJ. Vijay Franklin, K. ParamasivamIn this study, we propose to design a call admission control algorithm which schedules the channels for Real time and non-real time users. In Long Term Evolution (LTE) 3GPP Networks, several works were done on call admission control but these works rarely considers scheduling of resources to the real time and non-real time users.When the system meets traffic oriented performance … …Journal of Computer Science, Vol. 8, Issue 12 · 13 Dec 2012 · 6,791 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titlePerformance Analysis of Call Admission Control in WCDMA Systems with Mobility based Interference Margin ReservationS. Malarkkan, V. C. RavichandranThis study presents performance of call admission control and resource reservation schemes based on the mobility of the users in WCDMA cellular systems. In order to guarantee the handoff dropping probability, the mobility of the user is predicted based on a realistic mobility model. The mobility prediction scheme used in this study is used to estimate the set of candidate … …Journal of Computer Science, Vol. 2, Issue 10 · 31 Oct 2006 · 6,385 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsA Fuzzy Logic Based Power Control for Wideband Code Division Multiple Access Wireless NetworksN. Mohan, T. RavichandranProblem statement: Resource management is one of the most important engineering issues in 3G systems where multiple traffic classes are supported each being characterized by its required Quality of Service (QoS) parameters. Call Admission Control (CAC) is one of the resource management functions, which regulates network access to ensure QoS provisioning. Efficient CAC is necessary for the QoS provisioning in … …Journal of Computer Science, Vol. 8, Issue 8 · 4 Aug 2012 · 6,760 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsA Policy-Based Admission Control Scheme for Voice over IP NetworksSami Alwakeel, Agung PrasetijoProblem statement: In Voice Over IP (VOIP) network, when more calls are admitted to the network, more voice packet traffic is created. Since bandwidth is always limited, this may result network congestion and/or may affect voice quality. Thus, we needed a mechanism for improving the Quality of Service (QoS) by controlling VOIP calls admission. Approach: Given a specified bandwidth and … …Journal of Computer Science, Vol. 5, Issue 11 · 30 Nov 2009 · 6,614 accessesView PDF Cite
