| Node | Any device that is or can be part of an ESP-MESH network | |
| Root Node | The top node in the network | |
| Child Node | A node X is a child node when it is connected to another node Y where the connection makes node X more distant from the root node than node Y (in terms of number of connections) | |
| Parent Node | The converse notion of a child node | |
| Descendant Node | Any node reachable by repeated proceeding from parent to child | |
| Sibling Nodes | Nodes that share the same parent node | |
| Connection | A traditional Wi-Fi association between an AP and a station A node in ESP-MESH will use its station interface to associate with the softAP interface of another node thus forming a connection The connection process includes the authentication and association processes in Wi-Fi | |
| Upstream Connection | The connection from a node to its parent node | |
| Downstream Connection | The connection from a node to one of its child nodes |
