Dynamic Spectrum Access Network Scaling with Multiple Users: A Market-based Analysis

Sharing of hitherto licensed spectrum will be an increasing reality for future (next-gen) wireless broadband networks. In prior work, the authors introduced a novel method to quantify the opportunity cost of spectrum sharing between a single licensee (primary) - unlicensed (secondary) user pair that allowed meaningful comparison of various market mechanisms at equilibrium when applied to sharing. In this submission, we explore an important extension: how the opportunity costs and market equilibrium (prices and per-user rate) is influenced as a function of system scaling, i.e., N,M primary and secondary network users, respectively, under the assumption of `symmetric' physical layer for each user.
