SDN assisted middlebox synchronization mechanism for next generation mobile data management system

The middle box synchronization server maintains a dynamically changing data, which contains the data items which were requested and collected by the mobile devices from the server. The order and presence of tuples in the cache change dynamically according to the frequency of updates performed on the data, by the server and client. To synchronize, the data which has been modified by the client and the server at an instant are collected, batched together by the type of modification (insert update delete), and sorted according to their update frequencies. The SDN assisted synchronization algorithm for heterogeneous mobile database systems gives priority to the frequently accessed data with high usage. Theorems were written to show the current mobile data activity is reverse Y in nature and the experiments were tested for current high-speed networks for various mobile devices to show the reduced response time and energy consumption.
