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 | |
