Secure and Service-Oriented Framework for WiMAX Network

WiMAX is a Worldwide Interoperability for Microwave Access wireless communication system, which provides broadband access with large-scale coverage. To effectively set up multihop WiMAX networks, security is one of the major challenges that must be addressed. Another important issue is how to support different services and applications in WiMAX networks. In this article, we propose a service-oriented and secure network control framework for WiMAX networks. In the design of this framework, we consider both the security requirements of the communications and services WiMAX applications that have not been fully addressed previously in the network layer design. The proposed framework consists of two basic components: a service-aware control framework and a unified routing scheme. This paper can provide a guideline for the design of a more secure and practical WiMAX network.
