Abstract
Mobile users tend to submit transactions to servers nearby for execution so as to minimize the communication overhead incurred. Data replication is helpful because it can improve execution performance of servers and reduce network traffic. In this paper, a new algorithm named SDMP (shared data allocation algorithm based on moving pattern) is proposed, which takes not only the user’s pattern but also the frequency of user’s appearance according to the user’s path log into account. Experimental results show the SDMP algorithm is better than other algorithms used for data allocation for servers.
