Research ArticleOpen accessIn the keywordsUtility 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 · 6,785 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFuzzy Based Dynamic Buffer Management in Wimax 16m NetworksD. Karunkuzhali, Dinesh Chandra TomarIn WiMAX 16m networks, buffer allocation is the major problem to be handled for offering Quality of Service (QoS). The lack of buffers increases the packet loss and queuing delay. In this study we propose a fuzzy based dynamic buffer management in WiMAX 16 m network. The Base Station (BS) estimates the parameters such as number of user requests, flow … …Journal of Computer Science, Vol. 8, Issue 12 · 8 Nov 2012 · 6,812 accessesView PDFCite
Research ArticleOpen accessIn the keywordsLow Cost Test Bench to Assess Energy Efficiency of Communications Network EquipmentLuiz Henrique Biazotto, Alexandre de Assis Mota, Lia Toledo Moreira MotaCommunication network Quality of Service (QoS) degradation can lead to the consumption of additional energy to exchange information than that needed in normal conditions. If such behavior is known, network management can be more efficient and accurate, permitting to control more efficiently the energy consumption in telecommunication equipments. This study describes a test bench that can simultaneously measure the QoS … …Journal of Computer Science, Vol. 8, Issue 11 · 20 Sep 2012 · 6,678 accessesView PDFCite
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 · 6,755 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAn Optimized Ad Hoc on Demand Distance Vector Routing Protocol for Wireless NetworksV. Ponniyin Selvan, S. Senthil KumarProblem statement: Wireless Mesh Networks (WMN) is communication network made up of mesh routers and mesh clients, with mesh routers forming the backbone of the network. The WMN can be accessed by other networks through gateways and bridging functions in the mesh routers. The mesh clients can either be static or mobile with an option of forming a client mesh … …Journal of Computer Science, Vol. 8, Issue 7 · 21 Jun 2012 · 7,166 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Hidden Genetic Layer Based Neural Network for Mobility PredictionL. Velmurugan, P. ThangarajProblem statement: With numerous wireless devices increasingly connecting to the internet, WLAN infrastructure planning becomes very important to maintain desired quality of services. For maintaining desired quality of service it is desirable to know the movement pattern of users. Mobility prediction involves finding the mobile device's next access point as it moves through the wireless network. Hidden Markov models and … …American Journal of Applied Sciences, Vol. 9, Issue 4 · 11 Feb 2012 · 7,224 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Impact of Human Resource Practices and Organizational Citizenship Behaviors on Firm PerformanceDavood Babaei, Aminah Ahmad, Khairuddin Idris et al.Problem statement: The examination of organizational citizenship behaviors as the mediating variable through which human resource practices affect firm performance is still scarce. Approach: This study examined the mediation effects of organizational citizenship behaviors on the relationships between selected human resource practices and firm performance. The human resource practices studied were reward and performance appraisal practices and firm performance was … …American Journal of Applied Sciences, Vol. 9, Issue 1 · 5 Nov 2011 · 7,696 accessesView PDFCite
Research ArticleOpen accessIn the keywordsHybrid Traffic Management Model for Multi-Protocol Label Switching NetworkE. R. Naganathan, S. RajagopalanProblem statement: MPLS is a highly scalable, protocol agnostic and data-carrying mechanism. Traffic engineering is the major research area in MPLS due to the emerging requirements of MPLS and the internet usage. A major objective of traffic engineering is to minimize or eliminate high-loss situations. Another goal of traffic engineering is to balance the Quality of Service (QoS) against the … …American Journal of Applied Sciences, Vol. 8, Issue 12 · 15 Oct 2011 · 7,094 accessesView PDFCite
