Abstract
We study the successful transmission probability of cognitive radio ad hoc networks in which secondary users assist primary users on transmitting packets. We propose a half-slotted ALOHA multiple access control protocol. Primary transmitters sacrifice second half slot for the reliability improved by the cooperative transmission of secondary users. We derive the closed-form expression of successful transmission probability for both primary and secondary network in the first-half slot. In the second half, we obtain the bounds of successful transmission probability for primary network and the closed-form expression of successful transmission probability for secondary network. Numerical results show that the successful transmission probability of both networks could achieve a maximum by optimizing the intensity of secondary users in the whole time slot.
