The BOSSA Platform
BOSSA stands for BlueTooth and Sensors Array. It is a platform that developers can use to create applications that require the indoor location of an enduser in a multistory building. An array of BlueTooth Low Energey (BLE) beacons is the source of signals that are discovered by the end-user's smartphone when the application is invoked. A cloud-based database contains he idenities and locations of each member of the BLE beacon array. APIs associated with the database calculate the user's location using a trilateration technique wih sufficient accuracy to support many applications. Studets and faulty have created several applications that use the location information derived from the BOSSA Platform. Locating an emerbemergency caller in a multistory building is one application that uses the platform. Several papers describing the solution have been published. See PUBLICATIONS section for links.
