The IEEE 802.16e standard, often referred to as mobile WiMAX, specifies air interfaces for broadband wireless access (BWA) systems. The standard is expected to energize the BWA industry and open many opportunities to deploy systems in applications that were previously cost-prohibitive. Mobile WiMAX uses roaming and handoff to enable laptop and mobile phones to operate. High throughput is partic...

Wireless networks are very popular nowadays. Wireless Local Area Network (WLAN) that uses the IEEE 802.11 standard and WiMAX (Worldwide Interoperability for Microwave Access) that uses the IEEE 802.16 standard are networks that we want to explore. WiMAX has been developed over 10 years, but it is still unknown to most people. However compared to WLAN, it has many advantages in transmission spee...

For a broadband wireless standard such as WiMax, security is important and must be addressed. This is to ensure wide acceptance both from the perspective of the end users and the service providers. In order to compete with existing broadband cable or DSL services, the WiMax network must offer comparable security. We discuss the WiMax security mechanisms for authentication, encryption, and avail...

The emergence of WIMAX has attracted significant interests from all fields of wireless communications including students, researchers, system engineers and operators. The WIMAX can also be considered to be the main technology in the implementation of other networks like wireless sensor networks. Developing an understanding of the WIMAX system can be achieved by looking at the model of the WIMAX...

WiMAX and WiFi are considered as the promising broadband access solutions for wireless MANs and LANs, respectively. In the recent works WiMAX is considered suitable as a backhaul service to connect multiple dispersed WiFi „hotspots‟. Hence a new integrated WiMAX/WiFi architecture has been proposed in the literatures. In this paper the performances of integrated WiMAX/WiFi network have been inve...

The emergence of WiMAX has attracted significant interest from all the fields of wireless communication including students, researchers, system engineers and operators. Developing an understanding of the WiMAX system can be best achieved by looking at a model of the WiMAX system. Standards from IEEE and ETSL have been used to develop this model. The model presented in this paper built with gene...

The approval of the new mobile WiMAX helps in realizing the real time wireless broadband networks with large coverage area and high data rate. In mobile WiMAX whenever a subscriber comes into the cell radius of base station (BS), it has to get synchronized; this process in mobile WiMAX is termed as initial ranging. This paper proposes a novel Multiuser Detection for uplink mobile WiMAX with bet...

As a promising broadband wireless technology, WiMAX has many salient advantages over such as: high data rates, quality of service, scalability, security, and mobility. Many sophisticated authentication and encryption techniques have been embedded into WiMAX but it still exposes to various attacks in. This report is a survey of security vulnerabilities found in WiMAX network. Vulnerabilities and...

We are in advanced world of internet with new technologies in these days. So many new wireless networks technologies have been emerged. WiMAX and WLAN are such wireless technologies which are being adopted by most of the users. WiMax is one of the advanced technologies from those. Due to advancement, the security related issues has also been increased. Security has become one of the challenging...
