ABSTRACT
CAREER: Collaborative Communication and Storage for Sensor Networks in
Challenging Environments
NSF Proposal ID: 0953067
PI: WenZhan Song
This project concerns the sustainability and reliability of sensor networks in challenging (e.g., extreme) environments. In a challenged sensor network, a predictable and stable path may never exist, the network connectivity is intermittent, and a node could suddenly appear or disappear. The rare upload opportunity and unpredictable node disruptions often result in data loss. The unpredictable network disruptions make the traditional communication protocols inefficient and require a new design paradigm to combat network disruptions and maintain reliable operations. The driven research idea of this project is collaborative communication and storage - an integrated approach which cooperatively configures resources to increase disruption resilience, data persistence and network lifetime, and capture the fluctuating connectivity for data delivery. The expected outcomes of this project are (1) the innovative architecture principles, algorithms and protocols, design and evaluation methodologies for sensor networks in challenging environments, (2) the design and implementation of an integrated collaborative communication and storage middleware, and the running prototype sensor network systems in relevant environments, and (3) the curriculum and test bed enhancement for undergraduate and graduate research and courses, and educational outreach activities to K-12 students, minority groups and local communities. This project will greatly promote the confident use of sensor networks in challenging environments and enable new applications and economics. The outcomes of this project will be broadly disseminated to academic and industrial communities through international conferences, journals, media and intra-disciplinary and inter-disciplinary collaborations.

This NSF CAREER project concerns the sustainability and reliability of sensor networks in challenging environments. In a challenged sensor network, a predictable and stable path may never exist, the network connectivity is intermittent, and a node could suddenly appear or disappear. The rare upload opportunity and unpredictable node disruptions often result in data loss. The unpredictable network disruptions make the traditional communication protocols inefficient and require a new design paradigm to combat network disruptions and maintain reliable operations. The driven research idea of this project is collaborative computing, communication and storage - an integrated middleware cooperatively configures resources to increase disruption resilience, data persistence and network lifetime, and capture the fluctuating connectivity for data delivery. The middleware has three components. The Collaborative Topology Control middleware systematically adjusts radio configurations to combat network disruptions, increase network reliability and disruption resilience, and prolong network lifetime in challenging environments. The Collaborative Data Delivery middleware integrates collaborative routing, forwarding and network erasure coding protocols to capture the intermittent connectivity for disruption-resilient data delivery. The Collaborative Storage Management middleware collaboratively utilizes network storages to increase data persistence, so that the data more likely survives and eventually reaches a data sink, even as nodes fail. It greatly promotes the confident use of sensor networks in challenging environments and enable new applications and economics.
In this project, two PhD students were trained and graduated and a dozen of master, undergraduate and high school students have participated to learn and grow. The research has also resulted in five journal articles and ten conference papers, all in peer-reviewed competitive venue. The research results and testbed have also been incorporated into the teaching materials of course CSc4220/6220 Computer Networks, CSc8251 Sensor Web Architectures and Protocols.
