Abstract
In this paper, we have designed and developed a testbed for proof-of-concept demonstration and performance assessment of cooperative spectrum sharing (CSS) protocols. The performance of the testbed has been validated by obtaining both quantitative as well as qualitative results. Quantitative results are obtained by measuring the packet error rates for both primary and secondary systems during different times of the day whereas qualitative results are shown by utilizing a CSS protocol to successfully transmit two different images from primary transmitter (PT) to primary receiver (PR) and secondary transmitter (ST) to secondary receiver (SR) respectively. A parameter known as spectrum access probability which quantifies the probability of spectrum access for the secondary system is also measured.
