Wireless Test-bed for Mobile Computing Research

该项目创建了一个无线研究试验台，并整合了现有的有线分布式计算设施和多媒体实验室，使研究能够在无线环境中进行试验。目前的研究项目包括自适应能量感知分层路由机制、容错认证、动态资源分配、移动/无线网络中视频数据推拉传递的设计和评估，以及健壮的移动代理。该设施包括一些移动节点(一些移动机器人节点)，将允许对现有研究进行探索和增强，这些研究最初侧重于无线平台上的有线和分布式计算。由于有线分布式系统中所做的一些假设(例如信息的可忽略丢失、错误率、容错和可用资源)不再有效，因此在固定网络分布式环境中看起来健壮的算法在无线平台上表现完全不同。该项目的目的是在新平台上评估、研究和试验原型和分析结果，以了解在无线介质中的功率、带宽利用率、通信、存储成本、延迟和延迟等方面可能影响这些算法的效率和设计的参数。具体来说，该基础设施支持以下项目：自适应路由协议、容错和安全认证、健壮的移动代理、多媒体数据在移动网络中的高效传输。第一个项目研究了下一代无线网络的自适应节能路由方案、自组织无线传感器网络的功率控制和高效路由、分层路由算法、数据分发和聚合。第二个特点是虚拟代理建模、移动基站分层认证和复制移动代理。第三部分是故障情况下的操作；最后是移动/无线网络中视频数据推拉传输的设计评估和动态资源分配，以支持无线多媒体系统中的移动性。PIS在两个部门提出和开发了新课程，包括移动和传感器数据管理、高速网络、MEMS和无线传感器网络、无线通信系统、分布式系统、计算机安全和高级计算。新设施还将用于博士生、硕士和大四本科生。这些学生将补充他们在无线和传感器网络基础设施方面的项目，获得实践经验。该项目还探索了国土安全和商业应用。在军事环境中，这项工作探索了具有可移动基站的分层移动体系结构。

This project, creating a wireless research test-bed and integrating the existing wired distributed computing facilities and multimedia lab, enables research to be tried out in a wireless environment. Current research projects are in areas of adaptive power aware hierarchical routing schemes, fault-tolerant authentication, dynamic resource allocation, and design and evaluation of push-pull delivery of video data in mobile/wireless networks, and robust mobile agents. The facility, including a number of mobile nodes (some mobile robot nodes), will allow exploration and enhancement to the existing research, initially focused on wired and distributed computing, on a wireless platform. Because some of the assumptions made in a wired distributed system, such as negligible loss of information, rate of error, fault tolerance, and available resources, are no longer valid, algorithms that look robust in a fixed network distributed environment, behave totally different on a wireless platform. The project aims at evaluating, studying, and experimenting with prototypes and analytical results on the new platform to understand the parameters that can affect the efficiency and design of those algorithms in terms of power, bandwidth utilization, communication, storage cost, latency, and delays in a wireless medium. Specifically, the infrastructure supports the following projects: Adaptive Routing Protocols, Fault Tolerance and Secure Authentication, Robust Mobile Agents, and Efficient Transfer of Multimedia Data in Mobile Networks.The first project looks into adaptive power efficient routing schemes for the next generation wireless networks, power control and efficient routing for self organizing wireless sensor networks, hierarchical routing algorithms, data dissemination and aggregation. The second features virtual agent modeling, hierarchical authentication of the mobile base stations, and replicated mobile agents. The third looks at operation in the presence of faults; and the last, at design evaluation of push-pull delivery of video data in mobile/wireless networks and dynamic resource allocation to support mobility in wireless multimedia systems.New courses are being proposed and developed in two departments by the PIs, including Mobile and Sensor Data Management, High Speed Networks, MEMS and Wireless Sensor Networks, Wireless Communication Systems, Distributed Systems, Computer Security, and Advanced Computing. The new facilities will also be used for doctoral, masters, and senior undergraduates. The students will complement their projects on wireless and sensor network infrastructure getting hands-on experience. The project also explores homeland security and commercial applications. In a military environment the work explores hierarchical mobile architecture with movable base stations.
