Time slot allocation method and device based on time division multiple access and computer equipment

Abstract

The invention relates to a time slot allocation method and device based on time division multiple access, computer equipment and a storage medium. The method comprises the following steps of for each preemption period, calculating a preemption coefficient corresponding to a link of a target sending node according to a message sending queue length corresponding to the link of the target sending node and a priority corresponding to each data packet in the message sending queue, determining a first link meeting a preset preemption condition according to the preemption coefficient corresponding to the link of the target sending node, according to the preemption coefficient corresponding to the link of the target sending node and the preemption coefficients corresponding to other links in the target network, determining a second link meeting a preset preemption condition in each link of the target network, and allocating the target time slot in the second link to the first link to obtain an allocation result corresponding to the target sending node, and updating the fixed time slot table of the target network according to the allocation result. By adopting the method, the adaptability to flow change can be improved.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a time-division multiple access-based time slot allocation method, device, computer equipment and storage medium. Background technique [0002] Wireless Ad Hoc Networks (Ad Hoc Networks) is a network system that can be quickly deployed without relying on the existing fixed communication network infrastructure. Compared with ordinary mobile networks and fixed networks, it has the characteristics of no center, self-organization, self-healing, multi-hop routing and dynamic topology changes. The use of directional antennas can enable more nodes to send data in parallel at the same time, which greatly improves the degree of spatial multiplexing and can achieve the purpose of improving the transmission capacity of the Ad Hoc network. Therefore, wireless directional communication network has become a research hotspot. Among the many Media Access Control (MAC) proto...

AI Technical Summary

Problems solved by technology

If the allocation of fixed time slots is designed according to the high traffic conditions, it will cause a certain amount of waste. At the same time, too few dynamic time slots will reduce the flexibility of service transmission and make it difficult to adapt to changes in nodes in the network.

Therefore, the existing time slot allocation method based on time division multiple access is not adaptable to traffic changes, and it is difficult to find a good balance between resource utilization and performance
