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

Abstract

The present application relates to a time-division multiple access-based time slot allocation method, device, computer equipment and storage medium. The method includes: for each preemption period, calculating the preemption coefficient corresponding to the link of the target sending node according to the length of the message sending queue corresponding to the link of the target sending node and the priority corresponding to each data packet in the message sending queue ; According to the preemption coefficient corresponding to the link of the target sending node, determine the first link that meets the preset preemption condition; according to the preemption coefficient corresponding to the link of the target sending node and the corresponding preemption coefficients of the remaining links in the target network, In each link of the target network, determine the second link that satisfies the preset preemption condition; allocate the target time slot in the second link to the first link, obtain the allocation result corresponding to the target sending node, and Update the fixed slot table of the target network according to the allocation result. Adopting this method can improve the adaptability to flow changes.

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
