Towards a FOG-enabled navigation system with advanced cross-layer management features and IoT equipment
In this chapter, we present a cross-layer fog-enabled framework that offers visitors of small venues; such as museums, malls, convention centres, hospitals, and so on; enhanced context-aware experience and navigation services over 5G small-cell infrastructure. Distributed fog-enabled devices provide 5G networking throughout the surrounding establishment. The visitor, after signing into the network, is able to view various information and multimedia content concerning the narrow points of interest (POIs). The infrastructure also provides the ability to navigate the visitor throughout the establishment, using well-known positioning techniques. The positioning takes place with the mobile device receiving and juxtaposing the signal strength of small RF beacons sculling the local area. Finally, the network proposes other nearby POIs, depending on the user's preferences, based on the meta-data information stored inside the user's mobile device. The framework logic and calculations are transferred and sent back to the user through the cloud.
