Driver mental status plays a crucial role in ensuring road safety and factors such as fatigue, stress, and lack of attention significantly increase the risk of accidents. Conventional monitoring systems often rely on single indicators, which may not provide a comprehensive evaluation of driver condition. In this study, we propose a Fuzzy Logic (FL) based system for assessing driver condition by integrating multiple parameters, including physical parameters for deciding Driver Body Condition (DBC). We call this system FL-based DBC (FLDBC) system. As input parameters for FLDBC system we consider Pupil Dilation (PD), Driver Facial Expression Changes (DFEC), Handle Reaction Time (HRT) and Driver Heart Rate Status (DHRS). The output parameter is DCB. We evaluated the implemented system by computer simulations. The simulation results show that DCB is good when the pupil dilation is normal. With increasing HRT, the DCB value increased. Also, when DFEC and HRT changed, the DCB value increased.

Network slicing is a key enabling technology for 5G/B5G networks, allowing diverse services with distinct requirements to coexist on shared infrastructure. However, ensuring the trustworthiness of slices and improving performance, reliability, and security remains a significant challenge. This paper proposes a Hierarchical Fuzzy Trust System (H-FTS) to evaluate the trustworthiness of network slices. The system integrates Quality of Service (QoS) metrics (Latency, PLR, Throughput), Slice Failure Rate (SFR), Security Posture (SP), and Isolation Integrity (II). A lower-level Type-1 Fuzzy Logic System (T1 FLS) assesses the QoS score. This score, along with SFR, SP and II, is fed into an upper-level Interval Type-2 FLS (IT2 FLS) to compute Slice Trust (ST) score. Simulation results demonstrate the effectiveness of H-FTS, indicating that improvements in QoS, SP, and II have a positive impact on ST, while SFR shows a negative influence. The proposed H-FTS offers an interpretable and structured approach to trust assessment, essential for managing complex network slicing ecosystems.

The rapid advancement of wireless communication technology has had a significant impact on modern society, bringing about revolutionary changes in our daily lives and means of communication. In particular, introducing 5G and Beyond 5G (5G/B5G) networks is expected to expand communication coverage, including in the sky, at sea, and in outer space, while enabling ultra-low power consumption and low-cost communication. In order to adapt to such developments, Network Slicing (NS) is a technology that virtually divides the communication infrastructure to optimally allocate resources tailored to the requirements of individual services. Also, it is important to select slices that match the characteristics of each service. In B5G networks, individually optimized slices are required to support a wider variety of services and applications. To ensure that resources are distributed effectively without compromising the performance of any slice, in this paper, we propose a Fuzzy-based System for Selection of Slice Service Type (F3ST), which considers four parameters: Bandwidth (Bt), Latency (La), Connection Density (CD) and Slice Ability for Mobility Management (SAMM), which is a new parameter. From simulation results, we found that when Bt and SAMN are increased, the Slice Service Type Decision (SSTD) value is increased, but when La and CD are increased, the SSTD is decreased.

Wireless Mesh Networks (WMNs) are effective networks because they have high-robustness and rapid deployment capabilities. However, they have have some issues such as congestion, interference, diminished data transfer speeds, packet losses, and increased latency. The location of mesh routers is one of the most critical decisions to deal with these problems. However, determining the optimal location of mesh routers in WMNs is difficult task and it is known to be an NP-hard problem. In order to solve this problem, we propose and implement an intelligent simulation system based on Cuckoo Search (CS) algorithm, which is a meta-heuristic approach. In this work, we evaluate the performance of WMN-CS system considering Normal, Stadium, Subway and Uniform distributions of mesh clients. The simulation results show that the distribution of mesh clients affects the performance of WMN-CS. The Normal distribution achieves a faster convergence compared to the other distributions. Comparing Stadium and Subway distributions, the Stadium distribution converges faster than the Subway distribution. The Uniform distribution shows the slowest convergence speed and has the lowest NCMC values.

In Peer-to-Peer (P2P) networks, the peers should collaborate with trustworthy neighboring peers. However, it should be noted that in real applications, the peer may be faulty, which may make a wrong decision. For safe communication, the peers should be reliable. The reliability can be evaluated by the interaction of a peer with other peers but this procedure needs many parameters. In this paper, in order to make a qualitative evaluation, we implement a Fuzzy-based system and for quantitative evaluation we build another simulation system by taking into account the correlation coefficients and ns-3 simulator. Three parameters Packet Loss (PL), Delay Time (DT) and Throughput (TG) are considered for the evaluation of both systems. For Fuzzy-based system, the output is Peer Selection Decision (PSD). From the simulations results of FL-based system, we conclude that when PL and DL are increasing, the PSD is decreased. While, when TG is increased, the PSD is increased. By ns-3 simulator results, we found that by using the value of correlation coefficients is possible to select the best reliable peers.

The simulation results show that the distribution of mesh clients affects the performance of WMN-CS. In case of Uniform distribution of mesh clients, the convergence speed is faster than the Weibull and Chi-square distributions, but the converged value of NCMC is the lowest among these three distributions. In the case of Weibull distribution, the convergence speed is slower than the Uniform and Chi-square distributions, but the converged value of NCMC is the highest among three of them. The performance of WMN-CS for Chi-square distribution is between Uniform and Weibull distributions.

Wireless Mesh Networks (WMNs) are cost-effective and highly robust networks. However, WMNs have various challenges associated with wireless communication. To deal with these issues, it is needed to find appropriate locations of mesh routers. However, the problem is known as NP-hard problem. In order to solve this problem, we consider Cuckoo Search (CS) algorithm and implement an intelligent simulation system called WMN-CS. In this work, we evaluate the performance of WMN-CS considering different distributions of mesh clients. Simulation results show that for Normal distribution of mesh clients, the WMN-CS can find suitable mesh router locations for 30 phases. However, 200 phases are insufficient for WMN-CS convergence in case of Exponential and Weibull distributions.
