“…A novel channel scheme, referred to as Distributed Triggered Access (DTA) and discussed in [4], is explicitly crafted for the transmission of critical safety messages in platooning scenarios. In such scenarios, vehicles closely travel together in a formation, aiming to enhance both efficiency and safety.…”

This paper presents a comprehensive analysis of V2X communication, focusing on the transition from IEEE 802.11p to IEEE 802.11bd standards, and introduces an analytical framework combining M/G/1 queuing analysis and Markov chain analysis. Our model includes saturation and non-saturation states of Enhanced Distributed Channel Access (EDCA) in the scenarios with and without fallback mechanism for IEEE 802.11bd Next Generation Vehicles (NGV) and focuses on optimizing Transmission Opportunity (TXOP) allocation for legacy (non-NGV) devices whilst taking into account the impact of vehicle-toroadside Unit (RSU) distance. Our results show increased throughput for higher-priority traffic classes with augmented TXOP allocation for NGV devices and highlight the need to align RSU transmission coverage with On-Board Unit (OBU) data patterns and vehicle distance to prevent network saturation.

A Study of Channel Bonding in IEEE 802.11bd Networks

In recent years, Vehicle-To-Everything (V2X) applications have been actively developing, and the Quality of Service (QoS) requirements are becoming more stringent. To support V2X applications, IEEE developed the IEEE 802.11p standard in 2010. However, systems based on this standard fail to fulfill requirements on very low frame transmission delay and packet loss ratio imposed by modern V2X applications, such as applications for autonomous driving and platooning. To satisfy new requirements, IEEE has launched a new IEEE 802.11bd project to design the next generation of IEEE 802.11p. An important feature of IEEE 802.11bd is the channel bonding technique, which allows transmitting data in two adjacent channels simultaneously. Thus, it increases data rates and may reduce delays and packet loss ratio. The current version of IEEE 802.11bd specifies two channel bonding techniques, which differ from that used in modern Wi-Fi networks. This work evaluates the performance of the three aforementioned techniques from the IEEE 802.11 family of standards considering frame transmission delays and packet loss ratio. With rigorous simulations, it is shown that, in most cases, the channel bonding techniques highly decrease the percentage of both IEEE 802.11bd and legacy stations with unsatisfied QoS requirements on delays and packet loss ratio. Unfortunately, sometimes, the IEEE 802.11bd channel bonding techniques significantly worsen performance. Moreover, the work highlights that the choice of the primary channel for channel bonding techniques significantly affects the network performance. As a result, the paper provides a recommendation for selecting both the most suitable channel access method and primary channel.

“…Some research shows a reliable transmission method based on NOMA without the need for distributed scheduling. Since the random access mechanism of nondistributed transmission eliminates the risk of instability, we first studied the stability of the distributed free reservation access system based on the Foster–Lyapunov standard fast retransmission mechanism and then provided a stable noncooperative system to Control the probability of distributed transmission [ 14 ].…”

With the continuous development of Internet of Things technology, this technology is not limited to the laboratory but is more and more applied in the process of commercialization. Large-scale machine communication is one of the three most important scenarios for 5G applications. Its features include larger uplink access, smaller data packets, higher device energy consumption requirements, lower device transmission speed, higher latency, and bursty communication. With the development of the Internet of Things in the 5G era, interpersonal interaction experience has been further optimized and welcomed by the market and adopt Qt/embedded multilayer menu design mode to improve our computer system interaction to facilitate the operation and Maintenance system. The software function of the human-computer interaction system has reached the expected result. By constructing the application of a human-computer interaction system in the analysis of regional tourism competitiveness, we analyze the temporal and spatial changes of tourism competitiveness in four major economic regions in China and combine multiple linear regression and geographic detector models to analyze China’s tourism competitiveness. On this basis, we propose to further enhance the tourism competitiveness of areas with weak tourism development infrastructure and encourage potential tourism development areas to complement each other with high-quality resources between regions.
