SGER: Resource Management in Secure Open Wireless Networks

下一代无线网络将集中在开放的无线架构平台上。在这样的网络中，异构无线系统将被集成，以向具有不同传输特性、安全要求和硬件能力的各种用户提供可靠的、高带宽的、具有性能保证的按需服务。这个SGER项目正在探索这类系统的资源管理中的三个关键问题。首先，基于效用的模型来处理接入选择和垂直切换决策，其中管理网络操作的策略体现在边际效用函数的设计中。其次，提出了一种基于效用的QoS使能调度模型，在该模型中，给定时刻的效用可以反映系统在长期运行中所获得的生产率，并利用强化学习来做出处理多个QoS参数的调度决策。第三，一个完整的模型，测量所经历的安全关键任务的安全开销，并适用于安全意识的准入控制。拟议的研究重点是开发解决方案，是下一代无线和移动的通信网络系统的关键。研究结果的书面报告将通过学术出版物传播。

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.
