“…In real scenarios, since the moving nodes are constrained by the physical law of motion, the moving model should also be constrained by the physical law [36]. This means that the node motion in the HCMM model also follows this law, which can be achieved by limiting the velocity and acceleration.…”

Most of the existing mobility models use simple, linear motion to describe node movement, and there are few studies on curve movement patterns based on multiple obstacles in real scenes. How to describe the avoidance and curve movement patterns of nodes in multivariate obstacle scenes has become a key difficulty in mobility modeling. To address this, this paper proposes a mobility model based on Hermite curves, which fills the gap in curve mobility models for complex, multivariate obstacle scenes in mobility modeling. Firstly, the paper analyzes the demands of mobile patterns in real scenes, and then theoretically models the Hermite curve direction, combining node movement with Hermite curves to achieve curve movement, and adding perception parameters to avoid obstacles. To study the model's performance in practical scenes, this paper researches the spatial probability distribution of nodes and the spatio-temporal dynamic characteristics of network topology under the model's action, and defines the evaluation indicators of the model. To demonstrate the model's application performance, it is compared with the curve mobility model SRMM and the classic RWPM model. The results show that the model not only adapts to the obstacle avoidance application scenes with multiple obstacles, but also has a more uniform spatial probability distribution of nodes, better spatial coverage, and better spatio-temporal dynamic characteristics of the network topology composed of nodes than the SRMM and RWPM models. This model can provide a more realistic application scenes for the simulation of MANET.

Traffic management challenges in peak seasons for popular destinations such as Madinah city have accelerated the need for and introduction of autonomous vehicles and Vehicular ad hoc networks (VANETs) to assist in communication and alleviation of traffic congestions. The primary goal of this study is to evaluate the performance of communication routing protocols in VANETs between autonomous and human-driven vehicles in Madinah city in varying traffic conditions. A simulation of assorted traffic distributions and densities were modeled in an extracted map of Madinah city and then tested in two application scenarios with three ad hoc routing protocols using a combination of traffic and network simulation tools working in tandem. The results measured for the average trip time show that opting for a fully autonomous vehicle scenario reduces the trip time of vehicles by approximately 7.1% in high traffic densities and that the reactive ad hoc routing protocols induce the least delay for network packets to reach neighboring VANET vehicles. From these observations, it can be asserted that autonomous vehicles provide a significant reduction in travel time and that either of the two reactive ad hoc routing protocols could be implemented for the VANET implementation in Madinah city. Furthermore, we perform an ANOVA test to examine the effects of the factors that are considered in our study on the variation of the results.

“…The primary characteristics of these networks are the bandwidth and energy limitations imposed by them and their cooperative nature and complicated structure. There are a variety of applications for these networks, including tactical communication, defense, disaster management, traffic monitoring, and a variety of additional uses [1][2][3][4]. However, their dynamic nature [5] makes these networks more susceptible to a broader spectrum of assaults than other networks.…”
