“…The virtual experiment platform has entered the real field of scientific research and has an irreplaceable position in some design fields. The original software was gradually upgraded to the online version [4][5][6][7]. For example, a series of laboratories have shifted from relying on development to relying on network programming languages.…”

Virtual experiment platform is an open network virtual experiment system, and it is constructed by virtual reality technology. It virtualizes and digitizes experimental resources in the current virtual experiment platform. Virtual experimental platform is similar to real experimental platform. Users can adjust the virtual instrument to complete the experiment process. In this paper, a virtual experiment platform model of the fuzzy system is built. Based on the acquired correlative variables of the fuzzy system, a virtual experiment platform model of the fuzzy system based on the recursive fuzzy network is established. And the model is trained and modified by using the running data of the actual fuzzy algorithm, and the prediction of the fuzzy system in the process of virtual experiment platform is realized. The experimental results show that the virtual experiment platform model of the fuzzy system based on the recursive fuzzy neural network can obtain higher prediction accuracy. Compared with standard fuzzy neural network and other modeling methods, the model of virtual experiment platform of the fuzzy system proposed in this paper can obtain better prediction effect. So, the virtual experiment platform based on the fuzzy algorithm is feasible. The virtual experiment simulation platform of the fuzzy system is built, and the experiment design and research are carried out through the virtual experiment simulation platform.

“…The evaluation was performed by Android virtual machines in VirtualBox, so seemingly there might be no significant difference with Linux virtual machines. One advantage of this is that the modified code on the simulation platform can be almost directly used in real mobile operating systems [53]. We created mobile device nodes to communicate between nodes using WIFI for delivering data in the NS-3 simulator.…”

“…In addition, HMM was used in the connection states evaluation process based on the different transmission rates of interfaces. Because the experiments were carried out in FEP [53], it is not mentioned how well it scales for different network sizes, how it affects the energy consumption on nodes, or how much computational power is needed. These studies will be performed in our future work.…”

Multipath Routing and MPTCP-Based Data Delivery Over Manets

In some special circumstances (e.g., tsunamis, battlefields, and earthquakes), communication infrastructures are damaged or nonexistent. For communication among people, mobile smart devices (MSDs) can be used to construct mobile ad hoc networks (MANETs). This paper focuses on the problem of data delivery in MANETs aiming to improve the quality of service (QoS) and quality of experience (QoE) users receive. MANETs, however, have the well-known problems of frequent disconnections and high rates of failed transmissions as MSDs move in and out of network coverage areas, and the topology constantly changes. To solve these issues, the main contributions of this work are as follows: (1) we provide and investigate the QoE-driven multipath TCP (MPTCP)-based data delivery model in MANETs; (2) we present hidden Markov model-based optimal-start multipath routing, which can effectively predict a mobile node's near future network connection state according to its past connection state; (3) we leverage MPTCP to simultaneously transmit data via multiple interfaces of MSDs and improve the establishment method for MPTCP subpaths; and (4) we study and improve the algorithm of multihop routing in MANETs. The test results show that our algorithms can offer more efficient use of multiple subpaths and better network traffic load balancing than using standard MPTCP alone.

“…Technical Gap: Existing frameworks for validating networked systems differ based on the modeling fidelity of the various components. Simulation-based frameworks, such as [3], pursue an abstract (coarse level) modeling of all or some of the components. Researchers frequently rely on simulations as the preferred approach at the outset of their research and for initial validation of their ideas.…”

Emerging applications in the context of smart cities pursue a decentralized design that often involves numerous networked components. To validate such a design, the scientific community has resorted to software based simulators to find a way around the complexity of building large scale physical network test-beds. Network Simulator-3 (ns-3) is one of the most popular platforms for this purpose where communication-related performance metrics, e.g., latency and throughput, can be evaluated. Yet, concerns exist about the viability of such a simulated approach when assessing dependability metrics, e.g., trust and resilience to cyberattacks, since the misbehavior is mainly defined by the evaluator. Incorporating physical nodes within the simulated network would be advantageous in that regard. Advances have been made to connect network simulators, e.g., ns-3, to virtual machines to emulate communication with real devices. However, all efforts in the literature so far have been limited to a single physical host. This paper presents a framework where many external physical devices can act as a part of the ns-3 simulator and interact seamlessly with the nodes within the simulated network via Docker containers. Hence, our framework enables scalable and cost effective experimentation to validate dependability metrics like fault-tolerance and attack resilience. We demonstrate the utility of the proposed framework in evaluating performance under a set of attack scenarios.INDEX TERMS Hardware-in-loop experimentation, Dependability evaluation, ns-3, Docker.
