II-EN: A Heterogeneous Networking Test Bed to Support Middleware Services for Pervasive Sensing

该奖项是根据2009年美国复苏和再投资法案(公法111-5)资助的。嵌入式传感技术和无线传感器网络方面的重大研究进展使大量有趣的应用成为可能。为了进一步确保这项新兴技术得到更广泛的采用，无线传感器网络必须与其他现有网络(如WiFi和互联网)无缝集成。为了应对这种集成基础设施带来的挑战，该项目通过扩大现有的扁平和同构的传感器网络试验台，建立了异构型网络基础设施。HeteroNet集成了资源受限的传感器节点和更强大的传感设备、固定节点、移动节点和资源充足的服务器。这些节点以无线或有线方式通信。该测试台建立了一个实验基础设施，作为开发、测试、验证和评估研究人员当前针对混合网络上新兴应用的中间件服务的平台。受益于HeteroNet的研究包括：将可互操作的传感器网络集成到Internet，传感器网络中的无定形事件监控，以及针对支持服务质量的移动应用的系统状态监控。HeteroNet使研究能够进行通过模拟或现有的小型同构传感器网络测试台无法完成的研究。由HeteroNet支持的研究结果对推动下一代分布式系统和网络的尖端技术产生了深远的影响。HeteroNet的发展也使研究生和本科生的教育活动受益。HeteroNet用于促进和改进研究生和本科生有关网络、分布式系统、多媒体系统和计算机体系结构的课程。该试验台向校园内的其他研究小组开放，以支持许多尚未预见的与CESE相关的项目，促进不同研究人员之间更富有成效的互动。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).Numerous interesting applications have been enabled by embedded sensing technologies and significant research progress on wireless sensor networks. To further ensure a wider adoption of this emerging technology, seamless integration of wireless sensor networks with other existing networks such as WiFi and the Internet is a must. In order to address challenges that arise from such an integrated infrastructure, this project builds HeteroNet, a heterogeneous networking infrastructure, by augmenting an existing flat and homogeneous sensor network test bed. HeteroNet integrates resource constrained sensor nodes and more powerful sensing devices, stationary nodes, mobile nodes, and resource sufficient servers. These nodes communicate in wireless or wired fashion. This test bed establishes an experimental infrastructure to serve as a platform for development, testing, validation, and evaluation of the investigator's current research on middleware services for emerging applications on hybrid networks.Research benefiting from HeteroNet includes: integration of interoperable sensor networks to the Internet, amorphous event monitoring in sensor networks, and system status monitoring for QoS-aware mobile applications.HeteroNet enables research that is not possible via simulation or current small homogeneous sensor network test bed. The findings from the research enabled by HeteroNet have a profound impact on pushing the state-of-the-art of next-generation distributed systems and networks. The development of HeteroNet also benefits educational activities at the graduate and undergraduate levels. HeteroNet is used to facilitate and improve courses on networking, distributed systems, multimedia systems, and computer architectures at the graduate and undergraduate levels. The test bed is open to other research groups on campus to enable many as yet unforeseen CISE-relevant projects, stimulating more fruitful interactions among different researchers.
