Performance of Secondary Wireless Networks with Contention Control in TV White Spaces

摘要

In this paper we study the spectrum coexistence of secondary wireless networks with contention control and TV services. We propose to use the carrier sensing threshold as a parameter to control the density of secondary transmitters and through that the generated secondary interference to the TV system. For the calculated threshold we propose a simple method to assess the data rate of the secondary system. Using this method one can study whether the secondary performance is limited due to the TV protection requirements or not. Also, the method can be used to study the trade-off between the secondary performance and the TV protection requirement.
