THE RESEARCH OF SYNCHRONIZATION AND CONSISTENCY OF DATA IN MOBILE ENVIRONMENT
In the era of the mobile Internet,network environment is becoming more and more complex.In mobile environment,it cannot guarantee network reliability,terminals caimot be real-time networking,and cannot be easy to transfer larger files.To solve the network traffic burden caused by these problems,a new synchronization of data in mobile environment method to achieve the consistence is presented.This method uses log to store the differences,combined with optimistic replication method of C/S structure.It reduces the communication overhead and is effective in synchronization and consistency of data in multiple mobile terminals.This method has been applied in a mobile application of address book synchronization Assistant,and makes address book synchronization simple.Traditionally there are two buttons backup and restore,but this application changes them to one smart button sync.For any modifications in contacts,it can automatically maintain consistency in multi-terminals.
