Multiresolution storage and search in sensor networks
Deepak Ganesan, Ben Greenstein, Deborah Estrin, John Heidemann, Ramesh Govindan
Wireless sensor networks enable dense sensing of the environment, offering unprecedented opportunities for observing the physical world. This article addresses two key challenges in wireless sensor networks: in-network storage and distributed search....
Efficient disk replacement and data migration algorithms for large disk subsystems
Beomjoo Seo, Roger Zimmermann
Random data placement, which is efficient and scalable for large-scale storage systems, has recently emerged as an alternative to traditional data striping. In this report, we study the disk replacement problem (DRP) to find a sequence of disk...
Performance directed energy management for main memory and disks
Xiaodong Li, Zhenmin Li, Yuanyuan Zhou, Sarita Adve
Much research has been conducted on energy management for memory and disks. Most studies use control algorithms that dynamically transition devices to low power modes after they are idle for a certain threshold period of time. The control algorithms...
