Wireless communication is becoming very popular now a days. Worldwide Interoperability for Microwave Access (WiMAX) system in wireless communication plays an important role and has been attracting the researchers in the last decade. WiMAX system has provided anefficient solution for ‘last mile’ access technology to provide high data rate internet access for residential as well as small business...

IEEE 802.16 Worldwide Interoperability for Microwave Access (WiMAX) is an emerging broadband wireless communication standard used as a model of transmission and high speed Internet access. 3G Long Term Evolution (LTE) is the leading standard for wireless communication of high-speed data for mobile users. In this report we compare the performance of voice and video applications over WiMAX and LT...

The WiMAX Forum certifies and promotes the compatibility and interoperability of broadband wireless products where many testcases need to be developed for WiMAX procedures. In this paper, we develop a conformance test tool called ITRI-WiMAXT based on the TTCN-3 specifications. Then we show howWiMAX procedures are tested in ITRI-WiMAXT. Based on ITRI-WiMAXT, we have proposed several test procedu...

This article analyzes the performance of vertical handover between UMTS and WiMAX networks by defining development architecture for supporting mobility between these two technologies. First, architectures and principles of operation of networks UMTS and WiMAX are detailed and compared. Then the main protocols of mobility are considered as support of handover between UMTS and WiMAX (802.16). Fin...

In this paper, a research is described analyzing the solutions to the security issues in WiMAX (802.16e). At first a global overview of the technology WiMAX is given followed by an explanation of authentication and authorization for WiMAX. Then the security issues mentioned in literature are presented along with possible solutions. Next, the solutions are analyzed using criteria which are also ...

WiMax (Worldwide Interoperability of Microwave Access), also known as the IEEE 802.16 protocol is the latest standard for wireless networks. Its purpose is to expand the range of wireless systems access. We present here two patterns for this standard: WiMax Network Architecture, which describes the structural and dynamic aspects of these networks which are relevant for security and WiMax Securi...

Mobile WiMAX (Worldwide Interoperability for Microwave Access) is being touted as the most promising and potential broadband wireless technology. And the popularity rate has been surging to newer heights as the knowledge-backed service era unfolds steadily. Especially Mobile WiMAX is being projected as a real and strategic boon for developing counties such as India due to its wireless coverage ...

Several emerging studies have focused on the pricing issue of bandwidth sharing between Wi-Fi and WiMAX networks; however, most either concentrate on the design of collaborated protocols or figure out the issue without the overall consideration of consumer preferences and contract design. In this study, we explore a wireless service market in which there are two wireless service providers opera...

Based on the IEEE 802.16e standard, WiMAX proposes a Mobile Multihop Relay (MMR) approach defined in the IEEE 802.16j standard to extend the service area of Base Stations (BSs), and then improves the quality of received signal strength. Clearly, WiMAX MMR achieves a low-cost coverage-extension solution for the existing WiMAX network. WiMAX MMR supports three types of Relay Stations (RS): Fixed ...

IEEE 802.16 WiMAX is a promising new wireless technology for providing broadband ubiquitous network access. As more and more researchers and industrials are interested in simulating such networks, a number of WiMAX simulators have been emerged in the networking community. One of the most recent WiMAX simulator is the one developed for ns-3. This module provides a standard compliant and well des...
