The narrator: A smart data offloading system for interactive navigation in museums

Information and Communication Technologies (ICTs) are extremely important for sustainable development for all countries. It can be used to make information available in the right form to the right user at the right time in faster and better way. Archeological sites, museums and old towns are some of the fields that can take great advantages of such technologies. These places need a particular ICTs infrastructure and services to convert these physical locations into useful smart environments. In this paper we present the narrator; a system that assist visitors of such places and automatically delivering them in a smart manner with the required information according to their current position in this site. The key idea of the suggested system is to integrate Location Based Service (LBS) technology, data offloading, Wi-Fi networks and recommender algorithm to realize a smart self-guide system. This system is able to detect visitor position, create visitor profile, recommend a visiting map, interact with the visitor, and finally offload the textual and multimedia data to visitor´s device as if it makes objects of the site able to talk and narrate their story to visitors. The results of our suggested system showed that the narrator guarantees on-demand information delivery for large number of visitors simultaneously in the same site with high QoS and without service interruption or failure. In addition, the proposed system efficiently solves the run down problem due to the limited system bandwidth of the wireless networks.
