power communication service priority quality of service service differential scheduling neural network transmission delay band utilization
In order to guarantee the different quality of service requirements of smart grid services,the impact of transmission disruption and emergency data are considered and a QoS priority model based on the cognitive radio is established. A QoS-based differential services scheduling mechanism in smart grid communication networks is proposed. The neural network is introduced to optimize the transmission strategy,so that the average delay of the system is minimized. The simulation results show that the proposed scheme can guarantee the low transmission delay of high-priority secondary users while limiting the transmission delay of the emergency data to a very low range,and ensure the QoS requirements of all kinds of smart grid communication services.
