The Internet of Things (IoT) is spread across various layers, with different types of software being used across these. This article presents a list of open source software packages that can be used in each of the layers.
You might have read Gartner and many other business forecasts on connected devices and the Internet of Things (IoT) growth in the coming years. Billions of connected devices around us, as well as open hardware and software solutions, would play a key role in enabling a smarter life in the near future. Before proceeding to the list of open source software in this field, let us take a look at a few layers of the IoT architecture.
Layer 1 consists of end devices talking to the environment, which are also known as sensor nodes, typically powered by microcontroller based targets, wearables and, sometimes, Linux boards.
Layer 2 consists of gateway devices, typically Linux-powered target boards or handheld gadgets, for interfacing end devices with Cloud platforms and bridging protocols with their middleware support. High-end micro controllers with suitable frameworks can also be a choice here.
Layer 3 consists of servers, typically deployed on Cloud platforms. These provide services like authentication, data collection, data processing, analysis, storage, visualisation, Web integration, mobile app connectivity and more. This may be further divided into various sub-layers or components.
Let us examine some open source choices for development in each layer.
Layer 1
Toolchains. GNU ARM embedded toolchain provides pre-built toolchains as well as source codes for Cortex-M and Cortex-R processors, especially for bare metal code for microcontrollers. It has consistent releases in every quarter. The latest stable release is 2017 Q1, which ships with gcc v6.3.1 and is migrated to 64-bit Linux hosts, whereas the previous release of 2016 Q3 ships with gcc 5.4 and is available for 32-bit Linux.
