Abstract
This article conducts an indepth study on the delay caused by time division multiple access (TDMA) technology and theoretically analyzes some methods that can reduce the TDMA delay. Traditional dynamic time slot allocation algorithms usually only consider the completion of conflict‐free time slot allocation in distributed scenarios, but they do not clearly specify the order of time slot allocation. The order of time slots allocated to each node is ultimately consistent with the new data flow. The order of media dissemination is not the same. Aiming at the scheduling delay problem caused by the inconsistency of the new media low‐latency propagation time slot allocation sequence and the data stream sequence, a protocol using the master time slot adaptive time slot exchange technology is proposed. The protocol designs the corresponding super frame structure and realizes the neighbor node discovery strategy and the time slot allocation based on the priority list. At the same time, the time slot switching technology is used to adjust the time slot sequence so that it tends to the data flow sequence. The exchange criterion based on the low‐latency propagation data stream value of the new media is designed to solve the problem of optimizing the time slot of multiple data streams in the network. Through the simulation results and analysis, it can be seen that the architecture design proposed in this paper can fulfill the expected requirements of the wireless Mesh network and can achieve good low‐latency performance for the highly dynamic network topology. It can also achieve good performance in terms of network throughput and data flow delivery rate, and it has adaptability to high dynamic topologies. By comparing with the traditional algorithm design, the design proposed in this paper has a large improvement in low latency and high submission rate. Therefore, it can be considered that the low‐latency architecture design proposed in this article has better performance for new media’s low‐latency propagation and highly dynamic network topology.

Summary
With the integration and development of mobile communications and Internet technologies, the scale of informatization has grown rapidly, and new businesses and corresponding applications have continued to emerge [1]. The fourth-generation (4G) mobile communication network technology can no longer withstand the increase in network energy consumption and bit cost, and it is difficult to support a thousandfold increase in traffic capacity. We introduced the principle of the traditional dynamic time slot allocation algorithm and pointed out the existing problems and corresponding solutions. Aiming at the shortcomings of traditional dynamic TDMA, this paper proposes a new media propagation path sequence-based time slot allocation protocol algorithm SAOPPS-TDMA, which uses control information packet interaction to complete neighbor node discovery, and uses priority lists to complete distributed initial time slot allocation, alleviating the time slot scheduling delay overhead caused by the inconsistency of the time slot sequence and the data stream sequence, thereby increasing the data forwarding speed and reducing the data delay. The simulation shows that this design has a high Qos guarantee on the performance of low latency, high throughput, and high delivery rate
