AUTOMATIC RADIO SELECTION FOR DATA TRANSFER IN DEVICE-TO-DEVICE COMMUNICATION

Abstract

As technology evolves in telecommunication, the choice of the kind of radio to be used for data transfer in a multi-radio system at a particular time remains a challenge, especially in device-to-device (D2D) communications. This is evident in devices such as phones where multiple radio systems such as Bluetooth, Wireless Fidelity (WiFi), and Global System for Mobile communication (GSM) are present. Despite all these radios in place, the selection of these radios has always been done manually by users which introduces delay and increase in power consumption on the device. To mitigate this, there is a need for D2D to be able to automatically select radio for data transfer based on certain criteria. One of such criteria remains area of coverage as different radios have different ranges of coverage areas. To this end, this research presents automatic radio selection for data transfer for D2D. This was used via the use of a Geo-Position Service (GPS) module, Bluetooth device, Long range (LoRa) module, and an Arduino Nano. At the end of the research, the radio selection was possible and amount of energy consumed by the device within the period of twenty-four hours was 10%.
