Indoor Navigation Using BLE Beacons Smart Positioning System

Abstract

We have implemented an intelligent Indoor Positioning System by employing Bluetooth Low Energy technology with Raspberry Pi devices to make low-powered, low-cost transmitters communicating with android app providing a range of positioning services to both, the organizers and the attendees of that event. A positive new experience to indoor navigation for attendees by achieving the goal of user accessing useful information according to his current surrounding via a mobile app efficiently connecting to mesh network. Hence solution we are presenting enables a smart phone, any android device (BLE enabled) to perform actions when in close proximity to any of beacon and help a phone show notifications of items nearby and deployment of mesh network(WI-FI and socket programming) of Pi’s for routing and processing of information. This Project is an integration of Android application, BLE GATT protocol, Node.js, and Socket Programming. As for demo to our proposed solution we are providing its services at “OPEN HOUSE NUST 2015” where attendees will be facilitated by being able to access information related to projects they are currently standing nearby and as they will move data will change seamlessly, they can rate projects, can get notified by organizers and as an add on feature there is “panic button” if pressed by any user, aid is to be instantly sent to that location where that beacon has detected signal for help.
