CAREER: Designing Efficient Resource Management Schemes to Support Integrated Services in Mobile Computing Systems

随着互联网相关应用的迅速兴起，在移动计算系统中提供数据、语音、视频等综合服务变得越来越重要。然而，诸如蜂窝网络之类的移动通信系统主要是为支持语音而设计的。由于集成服务的工作负载特征和服务质量（QoS）需求不同，以前的资源管理技术可能无法有效地处理新兴应用程序不断增长的需求。为了解决这一问题，研究重点是：(1)带宽管理方案的设计和评估，以提供QoS保证并有效利用频谱；(2)缓存管理机制，降低带宽和功耗；(3)高效的协议，允许移动设备在大部分时间断电。该研究建议将这三个组件集成在一起，以提供一个资源管理基础设施，该基础设施可以有效地支持移动计算系统中的集成服务。研究成果将在本项目开发的无线网络和移动计算课程中得到应用和强调。

With the rapid emergence of Internet related applications, providing integrated services such as data, voice, and video in mobile computing systems has become increasingly important. However, mobile communicationsystems such as cellular networks are primarily designed for supporting voice. Due to the different workload characteristics and quality of service (QoS) requirements of integrated services, prior resourcemanagement techniques may not be efficient for handling the increasing demand of emerging applications. To address this issue, the research focuses on the design and evaluation of (1) bandwidth management schemesto provide QoS guarantees and efficiently utilize the frequency spectrum; (2) cache management mechanisms to reduce the bandwidth and power consumption; and (3) efficient protocols to allow mobile devices to poweroff most of the time. The research proposes to integrate these three components to provide a resource management infrastructure that can efficiently support integrated services in mobile computing systems. Theresearch results will be used and emphasized in the wireless networks and mobile computing courses developed in this project.
