Wireless Test-bed for Mobile Computing Research

这个项目建立了一个无线研究试验台，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功率感知分层路由方案、容错认证、动态资源分配、移动/无线网络中视频数据推拉传输的设计和评估，以及健壮的移动代理。该设施包括许多移动节点（一些移动机器人节点），将允许探索和增强现有研究，最初侧重于有线和分布式计算，在无线平台上。由于在有线分布式系统中所做的一些假设（如可忽略不计的信息丢失、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的行为完全不同。该项目旨在对新平台上的原型和分析结果进行评估、研究和实验，以了解在无线介质中影响功率、带宽利用率、通信、存储成本、延迟和延迟等方面的算法效率和设计的参数。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、健壮的移动代理和移动网络中多媒体数据的有效传输。第一个项目着眼于下一代无线网络的自适应功率高效路由方案，自组织无线传感器网络的功率控制和有效路由，分层路由算法，数据传播和聚合。第二部分的特点是虚拟代理建模、移动基站的分层认证和复制移动代理。第三种是在存在故障的情况下观察操作；最后，对移动/无线网络中视频数据的推拉式传输和支持无线多媒体系统移动性的动态资源分配进行了设计评价。pi正在两个部门提出和开发新课程，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、硕士和高级本科生。学生将在无线和传感器网络基础设施项目中获得实践经验。该项目还探索了国土安全和商业应用。在军事环境中，该作品探索了具有可移动基站的分层移动架构。

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system, such as negligible loss of information, rate of error, fault tolerance, and available resources, are no longer valid, algorithms that look robust in a fixed network distributed environment, behave totally different on a wireless platform.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.
