Building-linked Location-based Instantaneous Services System

For services which are meant to be used mainly inside buildings, a distribution using global app stores is inappropriate. Instead this work presents a provisioning system (BLISS) for building-linked location-based services. The multi-purpose application MultiApp implements the client-side of the BLISS specification. When a user enters a building, MultiApp instantaneously detects available services and allows to install and execute them. The client part of services is executed within the MultiApp environment and can provide functionalities similar to those offered by native applications. BLISS facilitates developing indoor location-based services by providing bi-directional communication between service providers and clients.
