Research ArticleOpen accessEvery word in the titleData Path Management Mechanism to Mesh Base Stations in WiMAXSahar Abdul Aziz Al-Talib, Noor Raad SaadallahThree options are popular today for design of wireless networks - Point-to-Point, Point-to-Multipoint and Mesh topologies. Worldwide interoperability of microwave access (WiMAX) is most often associated with the point-to-multipoint (PMP) topology. For some requirements, the configuration of the base stations (BSs) is aimed to be as mesh. Mesh offers a combination of point-to-point and point-to-multipoint capability by having each of … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 1 · 22 Mar 2019 · 7,972 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePerformance Evaluation of Handover in WiMax with TCP and UDP as Underlying ProtocolKaram Dhafer Mayoof, Rosilah Hassan, Amjed Sid Ahmed, Ahmed MarwanThe rejection of an ongoing connection/session is serious problem and it degrades the QoS and efficiency of the network rather than rejecting a request for new connection. The impact on performance of handovers is a serious problem in cellular systems that must be addressed. During handover there may be delay in packets and connections may drop. Real time applications i.e., … …Journal of Computer Science, Vol. 11, Issue 9 · 12 Dec 2015 · 7,244 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOPTIMAL RESOURCE ALLOCATION FOR LAYERED VIDEO MULTICASTING IN WIMAXHung-Yi Teng, Chun-Hung Wu, Ren-Hung HwangReal-time video disseminations over wireless links such as video telephony, video conferencing and mobile TV have become fast growing applications. In order to cope with the increasing users' demand, a new scalable and efficient wireless distribution platform is needed. With numerous advantages such as QoS assurance, high data rate and wide coverage, WiMAX has been regarded as an ideal choice … …Journal of Computer Science, Vol. 10, Issue 12 · 24 Dec 2014 · 7,410 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCOMPARISON FOR WIMAX SCHEDULING ALGORITHMS AND PROPOSAL QUALITY OF SERVICE IMPROVEMENT IN WIMAX NETWORKSR. Nandhini, N. DevarajanThe objective of the broadband wireless technologies is to ensure the end to end Quality of Service (QoS) for service classes. Wimax is a revolution in wireless networks which could support real time multimedia services. In order to provide QoS support and efficient usage of system resources an intelligent scheduling algorithm is needed. The design of detailed scheduling algorithm is … …American Journal of Applied Sciences, Vol. 11, Issue 1 · 19 Nov 2013 · 7,394 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Cross-Layered Path Stability Based Routing Protocol for WiMAX NetworksM. Deva Priya, M. L. ValarmathiIn IEEE 802.16, a Subscriber Station (SS) is battery powered with limited capacity. A SS can be made to operate for longer durations by deploying power saving features or by using relay stations. Multi-hop communication conserves power, but finding an optimal path to the destination is monotonous. Path stability indicates how stable a path is and how long it can … …American Journal of Applied Sciences, Vol. 10, Issue 11 · 9 Sep 2013 · 6,673 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEnhancement of Quality of Service Parameters in Wimax Mobile NetworksChandra, HelenPrabhaNext generation mobile networks are expected to provide seamless personal mobile communication and QoS. Since the demands for high speed Internet access as well as multimedia service had increased for last mile broadband access, the Scheduling is one of the most important components of BWA systems that affect system QoS provided to users. Priority queuing gives better throughput than the … …American Journal of Applied Sciences, Vol. 9, Issue 12 · 7 Nov 2012 · 6,833 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNetwork Planning and Optimization for Multi-Hop Relay Placement in WiMAX NetworksChitapong Wechtaison, Chutima PrommakProblem statement: Wireless access networks can provide high level of quality of services at low network installation budget if the networks are planned by using proper methods. In this research, we developed efficient network planning methods for Wireless Interoperability for Microwave Access (WiMAX) networks in which the multiple hops of relay stations are deployed. Approach: An integer linear programming model … …Journal of Computer Science, Vol. 8, Issue 9 · 9 Aug 2012 · 7,459 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDelay Analysis and System Capacity Control for Mobile WiMAX Relay NetworksAnas F. Bayan, Tat-Chee Wan, Sureswaran RamadassProblem statement: WiMAX relay is an emerging cost effective wireless last mile solution for rural and urban broadband Internet access. Approach: One of the key concerns of WiMAX operators is how many users they can support for an access area where the number of users and the amount of data that can be delivered to the end user depends on … …Journal of Computer Science, Vol. 6, Issue 10 · 5 Aug 2010 · 7,428 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFuzzy 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 accessEvery word in the titleDynamic Bandwidth Allocation for Multiple Traffic Classes in IEEE 802.16e WiMax Networks: A Petrinet ApproachS. Geetha, R. JayaparvathyProblem statement: WiMAX supports multiple types of traffic such as data, voice and video. Each flow requires a certain minimum bandwidth to achieve its QoS. Bandwidth allocation to traffic classes should be in such a way that fairness criteria is met with. Hence, we propose a dynamic bandwidth allocation mechanism to achieve fair and efficient allocation. Approach: We present a … …Journal of Computer Science, Vol. 7, Issue 11 · 6 Sep 2011 · 7,101 accessesView PDFCite
