Abstract
In this paper, we develop and analyze resource optimization protocols in two-way decode-and-forward relaying SWIPT-based cognitive sensor networks. The current schemes generally ignore the interference caused by secondary users’ transmission to primary users. However, when the channel between them is good, this neglect will have a bad impact on the analysis of the performance of both networks. Therefore, we investigate the maximum transmission rate that can be reached by secondary users under the premise of ensuring the communication quality of the primary users. We derive this scheme by jointly optimizing the transmit power of two secondary users and the power splitting ratio of the relay node, respectively. The tradeoff between the interference threshold and other system parameters is given in the numerical simulations to corroborate the effectiveness of the proposed solutions.
