“…• Slotted ALOHA: For slotted ALOHA MAC, time axis is divided into slots and each transmitting vehicular node accesses the channel independently at each time-slot with a certain probability, ρ ∈ [0, 1] on each road [39], [40]. This in turn leads to an independent thinning of the PPPs, so that λ M AC = ρλ R .…”

Visible light communication (VLC) has recently emerged as an affordable and scalable technology supporting very high data rates for short range vehicle-to-vehicle (V2V) communication. In this work, we advocate the use of vehicular-VLC (V-VLC) for basic safety messages (BSMs) dissemination in lieu of conventional vehicular radio frequency (V-RF) communication in road intersection applications, where the reception performance is affected by interference from the concurrent transmissions of other vehicles. We make use of stochastic geometry to characterize the interference from the same lane as well as the perpendicular lane for various network configurations, i.e., standalone V-VLC, stand-alone V-RF and hybrid V-VLC/V-RF network. Specifically, by modelling the interfering vehicles' locations as a spatial Poisson point process (PPP), we are able to capture a static two-dimensional road geometry as well as the impact of interference due to vehicles clustering in the vicinity of road intersection in terms of outage probability and throughput. In addition to above, the performance of spatial ALOHA and carrier sense multiple access with collision avoidance medium access control (CSMA/CA MAC) protocol for standalone V-VLC, standalone V-RF and hybrid V-VLC/V-RF network configuration for relaying BSMs at road intersection is also compared. The performance metrics such as delay outage rate (DOR) and information outage rate (IOR) are utilized to investigate the impact of latency associated with various network configurations. Our numerical results reveal that our proposed hybrid V-VLC/V-RF leads to significant improvement in terms of outage performance, throughput and latency as compared to stand-alone V-VLC or stand-alone V-RF network.

Artificial intelligence (AI) and brain networks are two very broad and complex research fields. They each have different priorities, but there are also intersections. Some AI systems, especially neural networks and deep learning models, are inspired by the structure of the human brain. These models attempt to process information by mimicking neurons and their connections. On the other hand, simulating and understanding human cognitive processes through AI models can help us better understand the working principles of the brain. Both fields are rapidly developing and providing us with profound insights into the essence of intelligence and how the brain works.

Due to the continuous and rapid expansion of the scale of the communication network, the deepening of the isomerization of the communication equipment in the network and the impact of network security factors, large-scale communication networks need to have a certain fault-tolerant mechanism to maintain connectivity for a long time. This paper studies faulttolerance from the perspective of structural statistics of communication networks. By studying how to make communication networks remain connected when some nodes fail, we can get the relevant laws, and provide the basis for highly reliable communication network deployment and the robustness of routing protocol design.
