A distributed coordination of a wireless network operating on different channels is provided by dispatching a device on each ‘home’ channel to regularly visit other ‘foreign’ channels to propagate and listen to broadcast information on these channels. The information in the broadcast packets transmitted on the home channel is relayed to the devices on the foreign channels by the dispatched device, as a ‘proxy device’ that operates on behalf of the other devices in the home channel. In a preferred embodiment, various aspects of this proxy process are optimized to reduce overhead and delays. Each channel is configured to distinguish home devices from foreign devices, to avoid contention between home and foreign devices. Acquired beacon slots on foreign channels are reserved to facilitate returning proxy devices. At the home channel, an anchor device alerts other devices of the proxy device's temporary absence and preserves the proxy device's beacon slot on the home channel.
