PROPOSAL: 0347674 INSTITUTION: George Washington Univ NSF PROGRAM: NETWORKING RESEARCH PRINCIPAL INVESTIGATOR: Cheng, Xiuzhen TITLE: CAREER: Integrated Resource Conservation in Sensor Networks Abstract Distributed networks of thousands of collaborative sensors promise unattended systems for many monitoring, surveillance and control applications. Sensor networks are expected to operate for long time. This makes network lifetime the central problem for a sensor network designer. This project pursues a system-level integrated approach to extend network lifetime. More specifically, new sensor location discovery methods are being developed that will conserve resources such as computational power and radio bandwidth within a sensor; new MAC protocols is being designed to optimize for low power, low data rate sensor networks; novel approaches are investigated for data aggregation services such as event detection and target counting. Because sensor self-positioning, MAC control, and data aggregation services in a sensor network are strongly dependent on each other, their interaction and design are jointly explored using an integrated approach for extending network lifetime.
