TL;DR: Economics Wired mesh network vs. star topology Well, the Internet is a mesh network. Why? Because DARPA wanted it to work even if half the United States were bombed into oblivion if the cold war was going hot. The military wanted a highly reliable network that is not dependent on any single node. Meshing or at least partial meshing your network ...

For simplicity, I'll describe this using a typical smart-home setup as a reference, but nothing here is really fixed by the application. The high level topology is equally suitable for a farm monitoring application covering several kilometres with thousands or sensors, tracking parking spaces in a city, or lighting management in an office building. I'll ...

Mesh networks tend to give better local configuration options for an IoT network. Range extension was already mention which the mesh network as each device in the network will help make the network bigger than each device would be alone. Another important aspect is how the messages are routed. While some devices will remain stationary, others may be moved ...

IoT is often used in home automation contexts (door sensors, wallplugs,...) and they tend to be very far each other especially in big houses. So a mesh network allows objets to cover the distance problem. Also, all these IoT devices must run low on energy so they must not waste it on long distance communications.
