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

该奖项由2009年美国复苏和再投资法案（公法111-5）资助。嵌入式传感技术和无线传感器网络的重大研究进展使许多有趣的应用成为可能。 为了进一步确保更广泛地采用这一新兴技术，必须将无线传感器网络与其他现有网络（如WiFi和Internet）无缝集成。为了解决这样一个集成的基础设施所带来的挑战，该项目建立了异构网络基础设施HeteroNet，通过增加现有的平面和同质传感器网络测试床。 异构网络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、移动的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。该测试床建立了一个实验基础设施，作为一个平台，用于开发、测试、验证和评估研究人员目前对混合网络上新兴应用的中间件服务的研究。将可互操作的传感器网络集成到互联网，传感器网络中的无定形事件监控，HeteroNet可以实现通过模拟或当前小型同构传感器网络测试床无法实现的研究。HeteroNet支持的研究结果对推动下一代分布式系统和网络的最新发展产生了深远的影响。 HeteroNet的发展也有利于研究生和本科生一级的教育活动。HeteroNet用于促进和改进研究生和本科生水平的网络，分布式系统，多媒体系统和计算机体系结构课程。 该测试平台向校园内的其他研究小组开放，以实现许多尚未预见的CISE相关项目，激发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.
