Analysis of Security of QoS in WiMAX and Mobile Networks

Summary/Abstract: In this paper we discuss several elements of importance for securing QoS in multimedia networks. Firstly, we present the first factor, which refers to understanding the characteristics of multimedia traffic in order to define and implement the QoS requirements. Secondly, factor refers to translation between QoS parameters that implies the distribution of system and network resources, and thirdly the factor establishes the appropriate QoS architecture that can provide the required QoS guarantees for multimedia applications. We have been analyzing security-critical applications such as remote operation, which may require a guaranteed level of availability (hard QoS). There are basically two ways to secure a guaranteed QoS. The first is simply to provide a lot of resources, enough to meet the expected peak (peak) requirements with a significant security margin. This approach generously oversupplies the (over provisioning) network. We gave a detailed security analysis as features of WiMAX. More precisely, our analysis is based on the claim that its key feature of the WiMAX network is that the security layer is built into the protocol leg instead of being added later, i.e. the security layer is complex between PHY and MAC layers.
