Summary: This paper investigates the performance of cooperative transmissions at intersections in the presence of interference for VSCs, considering factors such as decoding strategy and vehicles mobility, and determining the optimal relay position. The research shows that the outage probability performance of VSCs is higher at intersections than on highways, and the outage probability does not improve after the number of infrastructure relays reach a threshold value. The analytical results are validated through Monte-Carlo simulations.

Summary: This study analyzed the indoor blockage effects in the THz band and proposed a THz channel model, deriving the aggregated interference and theoretical expressions to approximate coverage probability and average network throughput. Results showed that for the nearest-AP user association scheme, the optimal AP density is 0.15/m^2, leading to improved coverage probability and network throughput.

Summary: This article examines the communication transmission performance of an RIS-assisted V2V communication network. By selecting the signal transmission mode and using stochastic geometry theory, the communication distance distribution and aggregate interference distribution of direct mode and RIS-assisted mode are calculated. The overall outage probability is evaluated for V2V communication in the direct mode. Numerical results show improved performance in RIS-assisted V2V networks with an optimized phase shift scheme. Monte Carlo simulation validates the analytical findings.

Summary: This article introduces and evaluates a technique for predicting interference levels in wireless networks. A recursive predictor is designed to estimate future interference values by filtering measured interference. Results show a good accuracy of predicted values versus true values within relevant time horizons, and the predictor also tends to work well in more general network scenarios.

Summary: This paper investigates physical layer security for a large-scale WSN with random multiple access, and proposes a random jamming scheme to defeat eavesdroppers. Analytical models are developed to characterize transmission reliability and secrecy, and an optimization problem is formulated to maximize the sum secrecy throughput. The results show that the random jamming scheme improves secrecy throughput, and the optimal jamming probability is determined by the trade-off between secrecy and throughput.

Summary: This research investigates the outage performance of the mmWave RSMA multiple-input-single-output system and proposes two beamforming schemes to enhance signal reliability. Closed-form expressions for the outage probability (OP) with the proposed schemes are derived using stochastic geometry theory, and expressions for the asymptotic OP are also derived. Monte Carlo simulation results are presented to verify the analysis and the effects of system parameters on the outage performance are studied.

Summary: In this paper, a cooperative satellite-aerial-terrestrial network (SATN) is proposed to assist aerial terminals in forwarding their information to a remote terrestrial destination. Statistical characteristics and outage probabilities are derived for the uplink and downlink between the aerial source, satellite/aerial relay, and the destination. Numerical results are presented to validate the analysis models and compare the outage performance of the considered cooperative SATN with different relay links.

Summary: This paper analyzes the performance of a UAV swarm network by characterizing the effects of UAV-to-UAV interference in terms of SINR. The model considers both deterministic and stochastic channel processes and incorporates hybrid LoS channels. The effects of network parameters on various KPIs are studied, and the model is used to evaluate the temporal evolutions of network outage probability given the UAV trajectories. The main advantage of the model is its ability to analyze the baseline outage probabilities of multi-UAV deployments.
