Non cooperative Cournot economic game model for heterogeneous coexistence in TVWS

In this paper, we formulated heterogeneous coexistence strategy in TVWS (TV White Space) between Primary Users (PUs), Cognitive Secondary Networks (CSNs) and TVWS coexistence standards using Cournot economic game model. Cournot economic game model is based on quantity and it is appropriate because, there are fewer TV transmitters in rural areas and hence, lots of TVWS spectrum channels per footprint. The robustness of the proposed model is that, it takes into account the unique SINR requirements of both PU and CSNs. While simultaneously, maintaining the key functionalities of heterogeneous coexistence framework. Contrary to the norm that, as PU continues to sell their licensed spectrum, revenue is maximized. Rather, it was discovered by way of simulations, such assumption never hold. However, Cournot point is simulated in which PU can maximize both revenue and QoS. In spectrum auction, an arbitrator is required to act as a spectrum broker, we propose the use of existing TVWS standards for this purpose. Thus, enabling coexistence between PUs and TVWS networks.
