A robust WiMAX scheduler for EPON-WiMAX networks
2012 IEEE Global Communications Conference (GLOBECOM), 2012The integration of WiMAX networks with EPON networks capitalizes on the large availability of bandwidth in optical access networks with the mobility provided by wireless technologies. In this integration, a WiMAX scheduler needs to take into account the variability of the channel capacity provided by the EPON scheduler.

Sixth International Conference on Networking (ICN'07), 2007
In recent time, new advanced wireless systems emerged at the world markets. One of the most promising is undoubtedly IEEE 802.16 standard, also known as WiMAX. For both, service providers and potential customers, is necessary to know its basic capabilities, such as the number of supported subscriber per BS or transferred data rate that may be delivered.

This article discusses the colocated coexistence of worldwide interoperability for microwave access (WiMAX) and Bluetooth in a mobile handset. It also proposes a measurement methodology that leads to a fundamental understanding of how WiMAX and Bluetooth interfere with each other in a colocated coexistence scenario.

A comprehensive WiMAX simulator
2011 IEEE Consumer Communications and Networking Conference (CCNC), 2011The most challenging issue in WiMAX network planning is to measure and enhance the Quality of Service (QoS) of WiMAX networks. In this paper, a comprehensive WiMAX simulator is proposed to evaluate the performance of the system. The key parts of the simulator are described including end-to-end communication path, traffic generation, Medium Access ...

2009 5th International Conference on Testbeds and Research Infrastructures for the Development of Networks & Communities and Workshops, 2009
Fixed WiMAX (IEEE 802.16d) is positioned as a wireless broadband alternative to the traditional cable and Digital Subscriber Line (DSL) technologies. Mobile WiMAX (IEEE 802.16e) has been chosen as the 3G/4G technology by major mobile/cellular service providers around the globe. Many Government organizations are also interested in the WiMAX technologies.

Steganography in WiMAX networks
2013 5th International Congress on Ultra Modern Telecommunications and Control Systems and Workshops (ICUMT), 2013The main subject of this work is to propose and analyze steganographic systems using WiMAX (802.16-2004) networks physical layer (PHY). According to this, two new systems were described. These proposals allow to create additional, hidden for unauthorized users channels used to transmission of secret messages.

Simulation Modelling Practice and Theory, 2008
Abstract The Network Simulator (ns-2) is a popular tool for the simulation of computer networks; it provides substantial support for simulation of Internet protocols over wired and wireless networks. Although some modules for WiMAX networks simulation have been proposed for the ns-2, none of them implements all MAC features specified by the IEEE 802 ...

On the WiMAX and HSDPA Coexistence
2007 IEEE International Conference on Communications, 2007In this work we develop Markovian models to study the dynamics of elastic calls in a cell served by HSDPA and WiMAX systems. We first present analytical models for interference and throughputs in WiMAX and HSDPA. We then consider two different strategies of joint radio resource management (JRRM) with or without inter-system vertical handovers and show ...

Multicarrier technology for 4G WiMax system [WiMAX/LTE Update
IEEE Communications Magazine, 2010As one of the candidate fourth-generation mobile communication systems, the IEEE 802.16 m-based WiMAX 2.0 system is required to provide up to 1 Gb/s peak transmission rate. The most efficient solution to achieve this challenging objective is to utilize wider channel bandwidth.

Scheduling Techniques for WiMax
2009This chapter proposes a state-of-the-art of scheduling techniques for WiMax. We first summarize the practical considerations of a WiMax scheduling algorithm in order to make a link between a scheduling algorithm and its implementation in WiMax. Then, we analyze the proposed use of some known algorithms for WiMax and then some scheduling algorithms ...
