Abstract

The unique characteristics of wireless networks pose a number of nontrivial challenges to multimedia applications with security and rigorous QoS requirements. Lack of adequate security protection is incapable of meeting security requirements of applications, whereas enabling excessive security services inevitably leads to further degradation in QoS due to additional computation and payload encapsulation. Early work, e.g. LAP, achieves balance by adjusting security policy according to QoS metrics; but none of them are security guaranteed. In this paper, we present an efficient risk-aware QoP (Quality of Protection) and QoS optimization algorithm for multimedia applications in wireless networks. It can achieve an optimization for QoP/QoS performance metrics through offering hierarchical security services and QoS support. Experiment demonstrates that even in high risk environments our scheme can efficiently balance QoP and QoS requirements.
