Hop-based burst-cluster transmission can improve fairness. However, its performance is degraded due to node synchronization. In order to resolve this issue, we propose the random scheduling method, where the burst-cluster transmission interval is not constant.
In this paper, we propose a distributed power control algorithm based on PID control and dynamic constraint condition for cognitive radio networks. In our proposed algorithm, at first, each transmitter in secondary networks receives the feedback information about signal-to-interference plus noise ratio (SINR) from its corresponding receiver. Based on the… (More)
