SGER: Resource Management in Secure Open Wireless Networks

点击翻译按钮获取中文摘要

Next generation wireless networks will focus on the open wireless architecture platform. In such a network, heterogeneous wireless systems will be integrated to provide reliable, high-bandwidth, on-demand services with performance guarantees to a variety of users with di®erent tra±c characteristics, security requirement, and hardware capabilities. This SGER project is exploring three key issues in the resource management of such systems. First, utility-based model is investigated todeal with access selection and vertical handover decisions in which policies governing the network operations are embodied in the design of marginal utility functions. Second, a utility-based QoS enabling scheduling model is developed in which the utility at a given moment can re°ect the received productivity of the system in the long term run and scheduling decisions to deal with multiple QoS parameters are made using reinforcement learning. Third, an integrated model that measuressecurity overheads experienced by security-critical tasks and is applicable to the security-aware admission control is developed. The proposed research is focused on the development of solutions that are critical for next generation wireless and mobile communication networking systems. Written reports of research findings will be disseminated through academic publications.
