Smart Home System Using Internet of Things Devices and Mesh Topology

Internet of things (IoT) has found its place in the modern world, and it continuously evolves. It is used in many areas varying from national defense systems to basic personal usages. One of the many areas that IoT devices are used is smart home systems. Smart home systems are gaining popularity because of their functionalities. They help users accomplish their tasks with swiftness and ease, which is a huge deal in busy lives of individuals. Pairing these already popular functionalities with more recent technologies such as Bluetooth, and Bluetooth Low Energy (BLE) mesh networks makes smart home systems even more useful. Using new versions of Bluetooth, which are specifically aimed at IoT applications, and a highly responsive topology like mesh significantly improves performance. In this project, the aim is to develop a mesh structure using Arduino integrated development environment (IDE). At the time, Arduino IDE does not support any BLE mesh libraries. Thus, to accomplish this, other libraries that provide connectivity to the chosen devices have been used. The functionalities needed to simulate a smart home system and the functionalities necessary for mesh networks have been implemented.
