User Discovery in Device-to-Device Communications

In this article, user discovery simulations are carried out in device-to-device communication in medium of Matlab within the frame of 3GPP standards. In this study, the random backoff method that has been touched upon several times in related literature and binary exponential backoff that has been used in IEEE 802.11 are compared. Simulation results reveal that the number of discovered users by the random backoff method is higher than the ones obtained by the conventional static resource allocation. Binary exponential backoff method is not as advantageous as the random backoff method.
