The IEEE 802.22 standard targets rural and sparsely populated regions exploiting television white space (TVWS) technology. In these regions, there are fewer mobile users per density and end-user traffic is light. Hence, there is a need to adopt traffic aware algorithm leveraging on the end-user nonuniform traffic attributes and in essence, promote spectrum efficiency in the TVWS spectrum-management regime. This paper investigates a mechanism to encourage spectrum sharing during low end-user traffic regime motivated by financial inducement. Since incumbent coexistence has been achieved using market models, it is tractable to apply market-assisted spectrum sharing models to address self-coexistence issues in TVWS networks. The purpose of this paper is to use the market model to promote self-coexistence in TVWS networks in the uplink self-frequency reuse. Toward this goal, this paper proposes discounted spectrum price game-based resource allocation in a competitive environment (D-GRACE). Specifically, D-GRACE is a transmit power reduction strategy motivated by financial incentives during light TVWS end-user traffic. When compared with an existing non-market-inspired TVWS self-coexistence resource allocation algorithm under the same scenario, D-GRACE exhibited superior power savings of about 20% and converged after five iterations.
