Patent ID: 10750433

Abstract:
Technology for gateway selection in a mesh network is described. In one embodiment, upon restart of a root node in the mesh network, the root node generates first Root Node Announcement (RANN) information and sends one or more announcement messages comprising the first RANN information to other mesh nodes in the mesh network. The RANN information comprises information about a type of backhaul connection between the root node and one or more network resources external to the mesh network and information about a cost metric defining a cost associated with utilizing the root node computing device to access the one or more network resources for each of one or more mesh nodes in the mesh network since those one or more mesh nodes do not have direct access to the one or more network resources. When the root node has sent a number of announcement messages that meets or exceeds a threshold amount determined in view of a total number of mesh nodes in the mesh network, the root node starts sending announcement messages with a second frequency that is lower than the first frequency.
