Reliable Battery-Aware Cooperative Multicasting for MBS WiMAX Traffic
Recently, relay agents selection schemes were introduced to support downlink multicasting in WiMAX single frequency networks. Such schemes were devised to work cooperatively in order to facilitate reliable Multicast Broadcast Multimedia Services (MBMS) traffic delivery over wireless channels without any consideration to mobile relay agents’ battery energy levels. In this paper, we introduce a b...
متن کاملA signaling architecture for multimedia MBS over WiMAX
In this article, we design and demonstrate a signaling architecture for multicast and broadcast services over a laboratory-emulated worldwide interoperability for microwave access (WiMAX) network. WiMAX is a broadband wireless access technology which includes different quality of service levels. Currently, a significant research effort focuses on data transmission optimization and mobility supp...
متن کاملPatterns for WiMax security
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...
متن کاملMobile WiMAX Network Security
WiMAX networks provide broadband data access to mobile as well as stationary users. While the wireless link is based on the 802.16e-2005 specification developed by IEEE, a complete network architecture “behind the base station” with global roaming support has been specified by the WiMAX forum. The security architecture for these networks covers EAP/AAA-based secure network access, secure bootst...
متن کاملAn Assessment of WiMax Security
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...
