Implementation of bi-directional blue-fi gateway in IoT environment

In the world of possibilities, IoT is playing a crucial role in development and automation of things which is making life easier, comfortable and most importantly reliable. This paper implements a new IoT Gateway, BLUE-FI designed to allow interconnection between Bluetooth and Wi-Fi protocols. This gateway gives us significant advantages. It enables us to transfer data between Bluetooth and Wi-Fi devices by renovating the protocols making it more simple and reliable, which obtains information from various sensors and convert them into a uniform format. With the huge possibilities in IoT, this paper implements an application of Blue-Fi gateway through Smart health monitoring system (SHMS). Here in SHMS we use different components to help us determine the health of a patient which is updated real time. This information, i.e., Bio-metric data is transferred to concerned Doctor and is also saved in cloud for future references in diagnosis. Our proof of notion demonstrates the performance and ability of the Bi-Directional Blue-Fi through smart health monitoring system (SHMS).
