CAREER: Integrated Resource Conservation in Sensor Networks

建议：0347674研究机构：乔治华盛顿大学美国国家科学基金会主席：网络研究主要负责人：程秀珍标题：职业生涯：传感器网络中的综合资源保护摘要由数千个协作传感器组成的分布式网络为许多监测、监视和控制应用提供了无人值守系统。传感器网络被期望长时间运行。这使得网络寿命成为传感器网络设计者的中心问题.该项目追求系统级集成的方法来延长网络的生命周期。更具体地说，新的传感器位置发现方法正在开发，将节省资源，如计算能力和无线电带宽内的传感器;新的MAC协议正在设计，以优化低功耗，低数据速率的传感器网络;新的方法正在调查的数据聚合服务，如事件检测和目标计数。由于传感器网络中的传感器自定位，MAC控制和数据聚合服务是强烈依赖于彼此，它们的交互和设计是共同探讨使用集成的方法来延长网络的生命周期。

PROPOSAL: 0347674INSTITUTION: George Washington UnivNSF PROGRAM: NETWORKING RESEARCHPRINCIPAL INVESTIGATOR: Cheng, Xiuzhen TITLE: CAREER: Integrated Resource Conservation in Sensor NetworksAbstractDistributed networks of thousands of collaborative sensorspromise unattended systems for many monitoring, surveillanceand control applications. Sensor networks are expected to operate forlong time. This makes network lifetime the central problem for asensor network designer. This project pursues a system-levelintegrated approach to extend network lifetime. More specifically,new sensor location discovery methods are being developed that willconserve resources such as computational power and radio bandwidth withina sensor; new MAC protocols is being designed to optimize forlow power, low data rate sensor networks; novel approaches areinvestigated for data aggregation services such as event detection andtarget counting. Because sensor self-positioning, MAC control,and data aggregation services in a sensor network are strongly dependenton each other, their interaction and design are jointlyexplored using an integrated approach for extending network lifetime.
