Gateway (GW) relocation of Access Service Network (ASN) includes changing the Anchor Point (AP)...
This paper presents the WiMAX- IEEE 802.16e real throughput analysis, measurement and evaluation. As throughput is a term with diverse definitions, the analysis starts from a theoretical modeling for throughput estimation in ideal radio propagation conditions, based on IEEE 802.16e standard and related works on throughput estimation. The tests were conducted using CTC (Convolutional Turbo Code) channel...
Worldwide Interoperability for Microwave Access applications and QoS specifications are based upon class based schemes. These service classes effect to QoS for user fairness and system utilization. Improved MAX C/I algorithm considers user waiting time and channel to interference ratio but not class based scheduling schemes, after including this neglecting condition algorithm solves the problem of...
This paper presents the technical study of the Radio Access Network (RAN) migration from WiMAX to LTE for the Internet Service Provider (ISP) Yota de Nicaragua. For our analysis, we conducted a case study in the city of Masaya, Nicaragua using predictive tool Atoll™, where we describe and simulate two scenarios. The first scenario represents the current WiMAX (IEEE 802.16e) network deployed on the...
LTE and WiMAX are the most important radio access technologies in the fourth generation mobile networks providing broadband access. The technologies bring strong QoS support, especially for multimedia services such as real-time video streaming, requiring bounded packet loss rate and delay. To reach these goals, effective packet scheduling schemes are needed to allocate radio resources. The function...
Based on the laws of the known mechanisms of the frequency resources scheduling in the download channel, solution of the problem raised in this paper assures QoS by available resources which directly influent on quality of design of the equipment. The WiMAX resource allocation algorithms determine which users to schedule, how to allocate subcarriers to them, and how to determine the appropriate power...
Day to day life people are using new technology and communication between user and it is easy in the new era, so the wimax is the worldwide interoperability microwave access(IEEE - 802.16) technology provide good accessibility to user and its results are better than the recent technology (2G,3G). In this paper I have implemented the performance and analysis result of wimax communication using recent...
This paper describes the fixed and mobile SDN access area network architecture, suitable nodes which can reduce consumption power more than 50% and feasibility test results for multi-resource high user experience layer 4 communication with MPTCP and OpenFlowSwitch.
Recently, broadband wireless communication serves as one of the most growing and developing technology in the field of telecommunications. The broadband provides multimedia services for voice, video, High Definition TV (HDTV), and games with certain Quality of Service (QoS). For these services, a high data transmission is greatly needed. Worldwide Interoperability for Microwave Access (WiMAX) Network...
WiMAX refers to Wireless Interoperable implementations of the IEEE 802.16 standards ratified by the WiMAX Forum has a main goal to deliver wireless communications with quality of service in a secured environment. The WiMAX MAC layer is designed to support different types of applications and services having different Quality of service (QoS) requirements. In addition of providing higher throughput...
In this paper, we propose a new scheduling algorithm for IEEE802.16 Broadband wireless Metropolitan Area Networks in TDD mode.

WiMAX delivers Quality of Service (QoS) to users based on a pre-determined traffic classification model. We develop an auction framework to bid for allocating the resources based on the utilities and traffic demands. We classify the users into two categories Premium User who has a high priority access and Non premium user having low-priority access. In principle larger the bandwidth more resources...
Quality of Service (QoS) differentiation measurement provides the ability to evaluate different level of QoS support in 4G networks such as Long Term Evolution (LTE) and Worldwide Interoperability for Microwave Access (WiMAX). Many research studies around the world have addressed the QoS Differentiation (QoS-Diff) considerations, however, to the best of our knowledge, only a few have attempted to...
Worldwide Interoperability for Microwave Access (WiMAX) is a broadband wireless access (BWA) technology. It provides high data rate and multimedia service.
