Based on the research and analysis of data acquisition mechanism in mobile cloud computing environment, this paper based on the research actuality and practical application at home and abroad, this paper makes a deep research on data caching technology, data prefetching technology and data replication technology in data acquisition, and puts forward the corresponding energy-saving strategy, which mainly includes the following three aspects: (1 Data caching technology: Through the research and analysis of traditional replica substitution algorithm, the paper puts forward the lirs (low inter-reference recency) substitution algorithm proposed by Dr. Zhang, Professor of Ohio State University, to replace the traditional strategy. An adaptive caching strategy pool has been designed, which implements these replacement policies LRU, MRU, LFU, MFU, FIFO, and Lirs, and makes a comprehensive comparison of this strategy with other policies in different access modes. (2) Data prefetching technology: After analyzing the traditional data prefetching system model, this paper puts forward the correlation of user access data by using the history access record of the mobile client, and combines with the mobile client to read and write the data resources in the network. The prefetch system of prefetching data selection by value evaluation function is a-PCMIP (power_based Cache Miss initiated prefetch) data prefetching system.
