WiMAX is a new technology that can provide long distance broadband wireless access based on IEEE 802.16 standards. After a short overview of IEEE 802.16 and the WiMAX network architecture, we center on the Quality of Service (QoS) support for multimedia applications in WiMAX. Inherent QoS support is an important factor differentiating WiMAX from other wireless access technologies, but so far ha...

WiMAX IEEE802.16e standard is proposed as an attractive wireless communication technology for providing broadband access. For the network and application-level capacity and performance analysis, we first provide a short overview on mobile WiMAX networks, and then describe mobile WiMAX PHY and MAC layer. Afterward we present and discuss the benefits and challenges of flat architecture for mobile...

Worldwide Interoperability for Microwave Access (WiMAX) is a telecommunications technology providing wireless data, voice and videos over long distances with efficiency.” The main goal of WiMAX is to deliver wireless communications with security or it can be said that security is the major issue in WiMAX networks. In this study, different cryptographic techniques like Advanced Encryption Standa...

95 ABSTRACT: The integration of WiFi and WiMAX will allow seamless connection between users from both systems with a greater capacity, higher bit rates and mobility access. To enable interoperability between WiFi and WiMAX a special gateway is required known as WiFi/WiMAX router. In this paper, we investigate, through the use of OPNET simulation tools, number of WiFi users or hotspots could acc...

Worldwide Interoperability for Microwave Access (WiMAX) embodies the IEEE 802.16 family of standards that provide wireless broadband access to residential and commercial Internet subscribers. While other WiMAX applications exist, there is an increasing trend to employ WiMAX for last-mile Internet access to circumvent the high deployments costs and local loop distance limitations associated with...

The industry landscape in telecommunications is changing rapidly at the moment. Services are increasingly shifting from voice to data and from circuit-switched to packet-switched ones. LTE and WiMAX are the two technologies poised to dominate next generation mobile networks. Battle between LTE & WiMAX technologies is already heating up with WiMAX being ahead due to availability of standards thr...

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. In this paper, three proposed chaos encryption techniques were described for video transmission...

Deployment Video on Demand (VoD) over the next generation (WiMAX) has become one of the intense interest subjects in the research these days, and is expected to be the main revenue generators in the near future and the efficiency of video streaming over next generation 4G is the key to enabling this. We are considering video streaming for real time video was coded by different H.264.x codes (H....

Mobile WiMax security standards from IEEE specify some powerful standards-based security controls, including PKMv2 EAP-based authentication and over-the-air AES-based encryption. But encryption technique does not guarantee a powerful secure end-to-end image transmission, and, consequently, WiMax presents a range of security design and integration challenges. In this paper, two proposed chaos en...

Worldwide Interoperability for Microwave Access (WiMAX) is a technology that bridges the gap between fixed and mobile access and offer the same subscriber experience for fixed and mobile user. Demand for such type of mobile broadband servicesaccess, which is further extended to support portability and mobility based on IEEE 802.16e, also known as Mobile WiMAX. However, frequent topology changes...
