Neighbor discovery and channel coordination of dynamic frequency selection (dfs) mesh networks

Abstract

Network hardware devices organized in a wireless mesh network (WMN). A first mesh network device performs a three-stage discovery protocol; in a first stage, a discovery scan uses a first radio to find a set of neighbor devices in proximity; in a second stage, a discovery locate probe process is performed on a secondary discovery channel that is from a same frequency band group as a first DFS channel; in a third stage, a CAC is performed via the first DFS channel and, after the CAC, a neighbor peering request is sent and a neighbor peering response is received from a second mesh network device via a second radio. The neighbor peering response confirms establishment of a first communication channel between the second radio of the first mesh network device and a radio of the second mesh network device over the first DFS channel.
