Abstract :
As the world moves into wireless communication times, there is an increasing demand for reliable, low-power, cost-effective, easy-to-access storage that can still provide adequate performance for multi-userspsila information retrieval. However, there is no current wireless system adequately fulfills all of these requirements of storage service. Wireless AP (access point) and router system provide no addition storage space for multi-users local access, only wireless networks access service. Some of home products are ill-suited for reliable, mobile, low-power and performance requirements of wireless storage because their no redundancy techniques, no battery power supply, high energy demands and no RAID system for high performance. Our novel system solution - Lynx, is a compact ad-hoc wireless network oriented storage system of intelligent, RAID-based, data reliably and power-saving. We achieved balance among capacity, performance and energy saving by combining request aggregation, chunk-based caching and the data popularity statistic. Our preparatory evaluation of Lynx shows that it can achieve significant performance gains.
