devices, situated in tourist spots, where tourists can store their data
without an Internet connection. Tourist spots are places and attractions
where tourists often visit. When local people visit the hubs,
they can then collect data from the hubs and in turn are able to upload
the tourists’ messages to the remote cloud servers using cloud
gateways. Cloud gateways are used to send information to the remote
cloud servers. Cloud gateways are situated in places like a
library, a university computer science building, etc., where local
users are able to access Internet connections for their mobile devices
to access cloud applications to upload tourists’ messages into
the cloud.
