From a technical point of view, Mobile WiMAX may offer an appropriate solution for delivering broadband wireless access. Two remaining questions, however, are whether the rollout of a WiMAX network is economically feasible or not, and how technical improvements like MIMO, beamforming and turbo-coding can influence the business case. In this paper different technical scenarios for a Mobile WiMAX...

The heterogeneous interface for the mobile node is the key feature for the next generation mobile world. It provides the flexibility for the mobile devices for moving devices to the next available best network for high data rate connection. So it is firstly important to develop in ns2 for the research and educational purposes. It is very important to develop it in ns2 so that we can do experime...

One of the challenges of the communication industry today is wireless data transfer with great speed. If the traditional Wireless Local Area Network (WLAN) is the leader for indoor usage (coverage and mobility on short distance), the mobile WiMAX is planned to be the adequate solution for the outdoor (when the user exist the hotspots coverage area). In this paper we propose a solution, based on...

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...

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...

The latest technology that provide broadband access with large coverage area is Worldwide Interoperability for Microwave Access (WiMAX), Since Mobile WiMAX has an important advantage to serve large coverage areas per base station, Mobile WiMAX has become a popular technology for handling mobile users. As we know that for serving a large number of Mobile Users in practice requires an efficient h...

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 ...

The IEEE 802.16e-2005 standard, also denoted as mobile WiMAX, was introduced as one of the first real efforts towards the deployment of fourth generation communication systems providing fixed and mobile broadband wireless access. Mobile WiMAX supports multiple input multiple output (MIMO) antenna techniques which are considered a key technology in wireless communication systems for increasing b...

WiMAX is the worldwide interoperability for microwave access, to provide business and consumer world wireless broad band services in metropolitan area networks. It has a target range of 31 miles and a target transmission rate exceeding 100 Mbps. Mobile WiMAX is an OFDM based technology for deployment which allows multiple-antenna operations to be performed on vector-flat sub carrier. Fixed WiMA...

Mobile worldwide interoperability for microwave access (Mobile WiMAX) based on IEEE 802.16e is a standard designed for metropolitan area networks (MAN) that cover an area wider than that covered by local area networks. Commercial WiMAX services are already available in some countries and regions. Services in Japan are scheduled to start in 2009. Mobile WiMAX supports “one-cell frequency reuse,”...
