Fast File Transfers from IoT Devices by Using Multiple Interfaces

Abstract

The Internet-of-Things (IoT) is a modern technological revolution that enables communication amongst a plethora of different devices. To date, about 30 billion devices have been connected to the internet and more than 75 billion devices are probably to be connected worldwide by 2025. These can range from small sensors and actuators to larger devices such as smartphones, drones or even buildings and interconnected cars. Devices are often mobile and battery powered thus their communication requires fast and energy efficient solutions. To this end, this paper studies the use of multi-interface communication for fast and energy efficient communication. In particular, we consider the basic operation of data transfer between smartphones in the form of files. This task can be performed for backup purposes, and hence it represents a useful and frequent operation that users perform. Our aim is to provide a new and easy means that optimises file transfers with respect to time and energy consumption. In particular, as smartphones are endowed with various connecting interfaces like Bluetooth, WiFi and 4G, we conduct experimental studies by varying different parameters in order to understand the best setting, including which interface is more appropriate to accomplish file transfer. To this respect, we also implemented an innovative and light app that allows the use of two or more interfaces concurrently. The experimental results show how the coupling of some interfaces might be effective in terms of time, while consuming a negligible amount of energy. Actually, such results become more and more interesting as the size of the file to be transferred grows. The best combination experienced is by making use of WiFi at 5 GHz concurrently with 4G, whereas WiFi at 2.4 GHz caused interference complications.

Security and Privacy for Low Power IoT Devices on 5G and Beyond Networks: Challenges and Future Directions

“…The low latency and improved performance requirement of IoT, especially in an industrial setting, was later supported by the authors of [154] in 2017. With research continuing in improving latency and overall performance on existing 5G infrastructure [155]- [157], it is becoming increasingly clear that existing networks lack the capacity and performance requirements for communication of IoT data. The slower transmission and latency delays on existing networks will worsen due to congestion, as has been previously highlighted.…”

On the Integration of Blockchain and SDN: Overview, Applications, and Future Perspectives

“…With the growing amount of always-online connected devices, the challenges to face within modern network environments have also grown. It is estimated that nowadays 30 billion devices are connected over the Internet and this number will reach 75 billion worldwide by 2025 [ 1 ]. This increase of devices is creating a massive number of issues such as attacks against the networking systems, data theft, addressing issues, sensors’ energy consumption and battery loss, etc.…”

Research on Remote Online Firmware Upgrade System for Embedded Devices

“…The remote online upgrade must consider the function of file breakpoint continuation. Relevant research [14][15] has been carried out to realize file breakpoint continuation by using FTP (File Transfer Protocol) protocol and HTTP (Hyper Text Transfer Protocol) protocol. These methods are suitable for downloading files based on the Web browser or file download tool.…”
