A BLE-based data collection system for IoT

The data collection is an important phase in the internet of things (IoT). The efficient way to collect data from the IoT environment is one of the challenges for the future of IoT. In this paper, we first design a data collection system for IoT. This system is based Bluetooth Low Energy (BLE) technology to forward the collected data from the data collector to the data gateways and proposes the use of smart phones as data collectors. We also propose a first prototype of this system. This prototype was developed with the help of two well-known open technologies, Arduino (Bluno) and Android. Finally, we evaluate the performances of the proposed system through performing a set of experiments on the developed prototype. The experiments show the feasibility and the applicability of the system especially where distance between the data collector and the data gateway is blow 6 meters. They also demonstrate the energy efficiency of the system.
