1. In a wireless network comprising a plurality of nodes, a method for selecting, by a first node, a channel for communicating with a second node, the first node having at least two network interfaces with radios tuned to orthogonal channels, the method comprising:

  • discovering network interfaces of the second node available for communicating with the first node;

    with respect to each available network interface of the second node, periodically making a channel quality estimate; and

    making a channel selection,wherein discovering available network interfaces comprises;

    broadcasting an address resolution protocol request;

    receiving on a first channel a first address resolution protocol response from the second node;

    recording medium access control address information contained in the first address resolution protocol response;

    initially selecting the first channel for communicating with the second node; and

    for each additional address resolution protocol response received from the second node, recording medium access control address information contained in the additional address resolution protocol response.
