Stochastic-Geometric Model of Expected Service Area for Cognitive TV White Space Wireless Networks
The authors address the problem of interference between cognitive wireless networks coexisting in the TV White Space (TVWS). They perform stochastic geometry analysis in order to evaluate the service area secondary cognitive devices can expect under mild to severe interference of neighboring networks. From their analysis, they foresee severe service area reduction, especially in densely populated areas, indicating a future need for coexistence techniques tailored to enable communication in TVWS while preventing harmful interference between cognitive wireless networks. Furthermore, they give a concise overview of the current activities undergoing in international standardization bodies towards the realization of communications in the TVWS.
