              Abstract: This paper is to study how to provide smart   services by analyzing each service history based on Cloud computing   in smart cities. Normally, users use each smart device to receive   their services while they stay in a place. In case they move and   visit to other place, the system prepares the service based on their   services history. At that time, although the users had visited and   had services in past, this visiting may ask other services. Then the   existing system usually generates new service, and next it provides   the service to the user. However, this method is inefficient,   because the system has to accept the number of process whenever all   users request the service. In this paper, it suggests the smart   service model that it keeps users' services history, which had used   them while the user stays to a place. The system catches the user's   visiting with the user's contexts in the smart device. The model   considers their plan/purpose based on old services, and it decides   if they modifies them by editing extra services. It calls the system   optimization and the suggesting method shows better efficiency after   experimenting.
