Abstract

Recently, the Internet of things (IoT) has become extensively used in our daily lives. This technology offers a new vision of the future internet where devices are interconnected and can communicate together. A big number of these devices complicates the firmware update and makes it more expensive since each node must be updated locally. Nevertheless, there are many cases where devices cannot change their location to upgrade the firmware locally due to an unreachable location or dangerous place. Therefore, it is necessary to remotely update the firmware of devices. In this study, the authors propose an efficient implementation of a low cost and secure framework of upgrading the firmware employing the latter On-The-Air programming technique. The authors present a proof of concept for a ubiquitous system applying wireless programmer. Our design offers a remote broadcasting of image code without disturbing the main functionality of nodes. The authors validated the performance of our design on a real network based on STM32 micro-controllers. The results showed the reduction of the network time-off, enabling a continuous operation of the ecosystem.

通过固件更新高效实现低成本、安全的框架

最近，物联网在我们的日常生活中得到了广泛的应用。这项技术为未来互联网提供了一个新的愿景，在未来互联网中，设备相互连接，可以一起通信。大量的这些设备使固件更新变得复杂，并且由于每个节点都必须在本地更新，因此成本更高。然而，在许多情况下，由于无法到达的位置或危险的地方，设备无法更改其位置以在本地升级固件。因此，有必要远程更新设备的固件。在这项研究中，作者提出了一种使用后一种空中编程技术升级固件的低成本和安全框架的有效实现。作者提出了一个应用无线编程器的泛在系统的概念证明。我们的设计提供了图像代码的远程广播，而不会干扰节点的主要功能。作者在基于STM32微控制器的真实网络上验证了我们的设计性能。结果表明，网络中断时间减少，使生态系统能够持续运行。
