Opportunistic wireless channel access by non-licensed users has emerged as a promising solution for addressing the bandwidth scarcity challenge. Auctions represent a natural mechanism for allocating the spectrum, generating an economic incentive for the licensed user to relinquish channels. A severe limitation of existing spectrum auction designs lies in the oversimplifying assumption that every non-licensed user is a single-node or single-link secondary user. While such an assumption makes the auction design easier, it does not capture practical scenarios where users have multi-hop routing demands. For the first time in the literature, the authors propose to model non-licensed users as Secondary Networks (SNs), each of which comprises of a multi-hop network with end-to-end routing demands.
