The term 'mesh network' refers to a type of network topology in which devices, or nodes, connect with one another directly, dynamically, and non-hierarchically. This structure allows for multiple paths for data transfer, increasing network reliability and resilience. If one node fails, the others can reroute data, maintaining uninterrupted communication. Mesh networks are particularly useful in settings where coverage is spotty or when a reliable connection is necessary, such as in IoT applications and smart home systems.
