Proximity-based services in mobile cloud scenarios using extended communication models

The progress in positioning technologies and the distribution of mobile devices with data communication capabilities promote the idea of providing proximity-based services. Proximity-based services deliver information and trigger actions, based on the location of users or devices. Recently, such applications became more popular in different facilities, such as shops, museums, and hospitals. Nevertheless, in most systems the service adaption is based solely on the location of a single user making the request. The presence or absence of other users is not considered. Furthermore, there is a need for a system, which can support the extension for different use cases without the need to change the program logic. The location of users is obtained by state-of-the-art wireless radio frequency technologies. How such a system can be designed for accessing mobile cloud data within a cloud computing ecosystem, as well as its feasibility is shown.
