Progress in Computing Applications Baiyi Huang 6 1 2017 http://www.dline.info/pca/fulltext/v6n1/pcav6n1_2.pdf Frequent disconnection of communication asymmetry, user data access pattern variability, energy limited mobile terminal is the typical characteristics of mobile computing environment. How can we ensure access to mobile data terminal efficiency in such “harsh” conditions, timeliness is research. With the development of computer technology, wireless communication technology, the development of mobile terminal technology, mobile computing technology is a new technology emerged. Mobile computing technology has brought great convenience to people’s access to information. People can use mobile devices through the network access device corresponding to the convenient access to the required information from the information source. The development of mobile computing technology has also brought the rapid development of the new field of mobile database. The mobile computing environment in large-scale users, asymmetric Kipling and down link communication, frequent communication link disconnection and computing environment data to the mobile distribution organization, has brought great challenges. To improve the efficiency of data access to the mobile terminal to this harsh environment, reduce the data access cost is an important research topic. From the data broadcasting technology, data etching and data caching techniques to study three aspects to improve the performance of mobile computing environment data access.
