Optimisation of a TV White Space Broadband Market Model for Rural Entrepreneurs

Abstract

Leveraging on recent TV white space communications developments in regulations, standards initiatives and technology, this paper considers a suitable next generation network comprising of two primary users (PUs) that compete to offer a service to a group of secondary users (SUs) in the form of mesh routers that belong to different entrepreneurs participating in a noncooperative TV white space trading. From a game theoretic perspective the non-cooperativeinteractionofthePUsisviewedasapricingproblemwherein each PU strives to maximize its own profit. Subsequently the problem is formulated as a Bertrand game in an oligopolistic market where the PUs are playerswhoareresponsibleforsellingTVwhitespectruminthemarketwhile the SUs are the players who are the buyers of theTVwhite spectrum.The PUs strategise by way of price adjustment, so much such that SUs tend to favour the lowest price when buying. The inter- operator agreements are based on the delay and throughput QoS performance optimization metrics respectively. A performance evaluation of both models is comparatively performed with regards to parameters such as cost, generated revenue, profit, best response in
