Internet of Things (IoT) is spreading everywhere and having an huge impact on the society by automating some actions and connecting everyday objects. IoT provides many improvements from the technological point of view, but has also some constraints due to the limited resources of the connected devices. The main application for IoT is home automation. In this field, the technology takes advantage of some protocols which are specifically designed for low-resources devices such as 6LoWPAN, 802.15.4 and Thread. This thesis focuses on studying the Thread protocol, a promising standard developed by Thread Group, that will become predominant in the IoT field.
