This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).A storage-centric heterogeneous sensor network (SC-HSN) consists of a large number of resource-poor sensor nodes at the lower tier and relatively fewer powerful master nodes at an upper tier. Sensor nodes produce and submit data to nearby master nodes which then answer the queries from the network owner on behalf of sensor nodes. SC-HSHs are ideal data sensing solutions in remote and extreme environments such as oceans, volcano, animal habitats, and battlefields. In such adverse environments, it is often impossible or prohibitive to maintain a stable always-on communication connection from the sensor network to the external network owner, and thus in-network data storage is a must such that data continuously produced by sensor nodes are stored inside the network and await ad-hoc queries via an on-demand communication connection.This project studies some fundamental open challenges associated with dependable data management in SC-HSNs. Specifically, there are three main thrusts in this project: (1) Distributed Fault-Tolerant Data Storage; (2) Privacy-Preserving Data Access Control; and (3) Verifiable Queries over Encrypted Data. The outcome of this research will advance the state of the art in data management in WSNs and provide an integrated solution to reliable, secure, efficient data storage and retrieval in SC-HSNs. The results of this project will also provide great insights for dependable data management in other types of emerging wireless networks such as mobile ad hoc networks, wireless mesh networks, and vehicular networks. The results of the project will be disseminated widely through publications and talks, and the proposed research will also be integrated with the education curricula.

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。以存储为中心的异构传感器网络（SC-HSN）由大量资源贫乏的传感器节点在下层和相对较少的强大的主节点在上层。传感器节点产生数据并提交给附近的主节点，然后主节点代表传感器节点回答来自网络所有者的查询。SC-HSH是在海洋、火山、动物栖息地和战场等偏远和极端环境中的理想数据传感解决方案。在这样的不利环境中，通常不可能或禁止保持从传感器网络到外部网络所有者的稳定的始终在线的通信连接，并且因此网络内数据存储是必须的，使得由传感器节点连续产生的数据被存储在网络内，并且等待经由On-hoc查询。本项目研究了SC-HSNs中与可靠数据管理相关的一些基本的开放性挑战。具体来说，该项目有三个主要目标：（1）分布式容错数据存储;（2）隐私保护数据访问控制;（3）加密数据上的可验证加密。本研究的成果将推进无线传感器网络中的数据管理技术的发展，并为SC-HSNs中可靠、安全、高效的数据存储和检索提供一个集成的解决方案。该项目的结果也将为其他类型的新兴无线网络（如移动的ad hoc网络、无线网状网络和车载网络）中的可靠数据管理提供重要见解。该项目的成果将通过出版物和讲座广泛传播，拟议的研究也将纳入教育课程。
