Abstract
A method of route discovery in wireless mesh networks comprises: receiving, using a first radio channel, by a first mesh network device of a wireless mesh network, a first route request identifying a destination mesh network device of the wireless mesh network, a first count of interfering communication links on a network path traversed by the first route request, and a second radio channel utilized by a second mesh network device along the network path; determining that the first radio channel matches the second radio channel; incrementing the first count of interfering communication links to produce a second count of interfering communication links; and broadcasting a second route request including an identifier of the destination mesh network device, a value reflecting the second count of interfering communication links, and an identifier of the first radio channel.
