System for fast and seamless communication among user devices

Abstract

With the recent popularity of the Internet of Things and a variety of wearable smart devices available today, a single user might have multiple such devices associated with them. Most of such devices communicate using Bluetooth (BT) or similar protocols, which need device discovery and connection establishment. These processes are time and power consuming, before they can be used to transmit data to one another. It would be useful to have a method to enable automatic and seamless connection establishment for devices associated with the same user, eliminating the discovery procedure. In this paper we propose such a system. Our system is based on the insight that the biometric parameters are the same for any one user. In our solution we designate a master Bluetooth device for a user at any point in time, assigning it with a specific Bluetooth address (BD_ADDR or MAC Address), temporarily replacing the original Bluetooth address of the device. This Bluetooth address is generated out of the bio-metric identity of the user with whom the device is associated. This enables any new device, when associated with the same user, to generate the BT address and get connected to the designated Master device by bypassing the conventional discovery procedure. Once the BT address is determined, the rest of the connection establishment process remains unchanged. Using this method, we consider a few unique use cases where our system can be used. This patented method is currently proposed for commercialization in upcoming wearable device models.
