Dynamic channel selection in a wireless communication network
First Claim
1. A network device for dynamically switching a communications channel within a wireless communication network of networked devices, the system comprising:
- a congestion detector circuit of the network device that accumulates an ineffective transmission time metric over time on a first channel of the wireless communication network and detects that the accumulated ineffective transmission time metric satisfies a channel selection condition on the first channel;
a network channel coordinator system of the network device and coupled to the congestion detector circuit that signals the networked devices of the wireless communication network to switch communications to a second channel, responsive to detection that the accumulated ineffective transmission time metric satisfies the channel selection condition on the first channel; and
a tuner circuit, a transceiver circuit, and an antenna coupled to the network channel coordinator system that initiate communications by the network device on the second channel, the congestion detector circuit accumulating an ineffective transmission time metric over time on the second channel of the wireless communication network after initiation of the communications by the network device on the second channel.

Abstract
A dynamic channel selection approach for wireless communication networks is provided by measuring an ineffective communication metric on a currently-used channel. The network can switch channels if the ineffective communication metric from a device on the network satisfies a channel selection condition. To change the wireless communication network to the new channel, all network devices in the wireless communication network are instructed to switch to the new channel. As network communications start on the new channel, the ineffective communication metric measurements begin again on the new channel. Communications on the new channel continue until the channel selection condition is satisfied on the new channel, at which point another random selection of a channel is executed. The process continues in such iterations during the operation of the network and its network devices.
