In some applications and systems, such as the Internet of Things (IoT), wireless communications, intelligent transportation systems, and the like, the importance of time and time accuracy is very high. In these cases, having up-to-date information, from It is important for systems to be able to make real-time decisions based on new information.Also, in some systems and processes, the need for information in supply chain, inventory management, planning and up-to-date and high quality in order to There is optimization and reduction of resource wastage, such as production and other business processes, having up-to-date and accurate information allows better decisions to be made and better results to be obtained. In addition, in communication networks, such as the Internet, fifth generation (5G) and sixth generation (6G) mobile phone networks, and machine-to-machine (M2M) communication networks, there is a need to transmit data with the lowest possible delay and in Timeliness is very important. Hence, with newer information, this delay can be reduced and communication between devices can be improved. Recent research shows that traditional design principles, such as high throughput, low latency, etc. It is not enough to increase the freshness of the information on the receiver side, so a new measure called information age was created, which measures the amount of time that has passed from the moment of the last update to the present. In AoI, queuing can be used to measure and better manage the age of information in networks and communication systems. Queuing can maintain the order of information, manage network traffic, and control resource consumption. In this research, the use of time-priority queue has been proposed to improve the age of information, this queue has considered the two factors of priority of packets and the time elapsed since the generation of packets as a priority function. By using this queue, the importance of each package considering the priority for them and the importance of novelty in the age of the information considering the time elapsed since the package production is considered. In this research, it was tried to improve the average and peak age of information by using this type of queue.
