Abstract-- Device coordination in open spectrum systems is a
challenging problem, particularly since users experience varying
spectrum availability over time and location. We propose a
distributed coordination approach that handles spectrum hetero-
geneity without relying on the existence of a preassigned common
control channel. Our approach carries potential to provide robust
operation under network dynamics. While this approach can be
implemented by upgrading the legacy protocol stack without
modifying the MAC protocol, we also describe modifications
