Yanchao Zhang, PhD, an assistant professor in the department of electrical and computer engineering at NJIT, has received a National Science Foundation Faculty Early Career Development (CAREER) Award for his research project entitled "Dependable Data Management in Heterogeneous Sensor Networks."
The award provides $400,000 between 2009 and 2014 to support Zhang's research and teaching activities. The CAREER Award is one of the NSF's most prestigious awards honoring scholars who are likely to become academic leaders in the future.
"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-HSNs are ideal data-sensing solutions in remote and extreme environments such as oceans, volcano, animal habitats, and battlefields," he said.
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. 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.
The outcome of this research will advance the state of the art in data management in wireless security networks 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.
Zhang is the director of the Wireless Networks and Security Laboratory at NJIT which works on research topics in network an
