Spectrum sensing is the premise of cognitive radio, which determines the communication quality of the total system. For the cognitive nodes far away from the primary user, the probability of correct detecting drops clearly because of the great fading, no matter they spend more time sensing. Cooperation between relay nodes can enlarge the valid transmit distance and improve the quality of communication...
In this work, we analyze the throughput, delay, and energy efficiency of random access sensor networks that employ Slepian-Wolf distributed source coding (DSC) and study the impact of MAC protocol design on these performances. Suppose that N sensors observe correlated information from the environment and that their local data are sent to a sink node through direct transmission links. To eliminate...
