Smart Mall scenario: Consider the scenario where an
infrastructure is installed inside a shopping mall and users
are running a related application on their smartphones. A
web portal is used by store owners to register their shops,
create a store profile, enter content that will be distributed to
potential customers, or setup several services of the system
(e.g., allow users to send feedback). A set of content is
defined by the mall stores that have registered to the system
and the selection of content that is transmitted to the enduser
depends on his preferences. Customers register their
interests, preferences, special needs or their planning for
their purchases through the web portal or a smartphone
application during movement inside the stores.
