The roots of the concept of DT are almost 2 decades old, but the fast progress in enabling technologies, especially in data analytics, artificial intelligence, and the Internet of Things, has accelerated the evolution of DT during the last 5 years. The growing interest, increasing development activities, and increasing business opportunities of the concept are also feeding the hype in the media. Consequently, this has led to the scattering and even misuse of the concept and its definition. In this article, we discuss different applications of DTs and what kinds of solutions there are for DTs. We analyze some most cited definitions of DT in the scientific literature and discuss the interpretation of the definitions through a hypothetical case example. Furthermore, we discuss different life cycle aspects of DTs and potential risks that may arise. To further concretize the concept of DT, we introduce ten reported case examples of implemented DTs in the scientific literature and analyze their features. Finally, we discuss the future development directions of DTs and the aspects that will affect the development trends.","PeriodicalId":308773,"journal":{"name":"Frontiers in The Internet of Things","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123668489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, maintaining and executing business choreographies are complex tasks. Moreover, enabling robust and reliable execution is important, as failures or delays cause high costs among partners. For example, manufacturing companies usually depend on different suppliers, and it is crucial to be up-to-date about possible delays in shipments as this leads to delays in the manufacturing of their products. In this case, a choreography needs to be designed and operated in a way that it can adapt to cope with such problems. This requires i) timely recognition and tamper-resistent logging of problems that occur at each involved partner, which are referred to as situations in the scope of this article, and ii) an approach for a timely adaptation of choreographies based on occurring situations. Therefore, in this article, we introduce DiStOPT, an approach to i) model and recognize situations in a distributed and timely manner, and ii) model and execute situation-aware choreographies based on the recognized situations. The contributions are evaluated in a manufacturing scenario and validated by a prototypical implementation.","PeriodicalId":308773,"journal":{"name":"Frontiers in The Internet of Things","volume":"693 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130910649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The traditional methods to solve these ever-growing security issues in VANETs are mainly cryptography-based. As an effective and efficient complement to those solutions, trust management solutions and reputation models have been widely explored to deal with malicious or selfish vehicle intrusion and forged data spoofing, with the aim of enhancing the overall security, reliability, trustworthiness, and impartiality of VANETs. For the integrity of the article, this survey begins with providing the background information of VANETs, including the basic components and general architecture. Then, many attacks in VANETs are investigated, analyzed, and compared to understand the functional relevance of the following trust and reputation methods. Various approaches offer various countermeasures against these types of attacks. At the same time, the latest development of emerging technologies such as blockchain, software-defined network, and cloud computing opens up new possibilities for more and more promising trust and reputation management models and systems in VANETs. After that, the survey reviews the most important trust and reputation models and schemes which are widely mentioned in the literature based on our developed technique-based taxonomy, in contrast to the popular “entity-centric, data-centric, hybrid” taxonomy in the field, to adapt to the recent technological development of these management schemes in VANETs. Finally, discussions and speculations on the future direction of research into the trust and reputation management in VANETs are presented.","PeriodicalId":308773,"journal":{"name":"Frontiers in The Internet of Things","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123700394","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Examples include deeply immersive augmented reality, wearable cognitive assistance, privacy-preserving video analytics, edge-triggered serendipity, and autonomous swarms of featherweight drones. Such edge-native applications require network-aware and load-aware orchestration of resources across the cloud (Tier-1), cloudlets (Tier-2), and device (Tier-3). This paper describes the architecture of Sinfonia, an open-source system for such cross-tier orchestration. Key attributes of Sinfonia include: support for multiple vendor-specific Tier-1 roots of orchestration, providing end-to-end runtime control that spans technical and non-technical criteria; use of third-party Kubernetes clusters as cloudlets, with unified treatment of telco-managed, hyperconverged, and just-in-time variants of cloudlets; masking of orchestration complexity from applications, thus lowering the barrier to creation of new edge-native applications.

They weave themselves into the fabric of everyday life until they are indistinguishable from it.” It was 1991 when Mark Weiser’s pioneering article was published in the Scientific American, discussing a future where networked devices would be so ubiquitous that “no one will notice their presence” (Weiser (1991)). To a large extent, this is our reality today. We may have changed terminology and moved from ubiquitous computing to Internet of Things, but the substance has not changed. We are surrounded by data-capturing computing devices that are always on, are networked, and many of which can perform world-altering operations. Just think of hopping into a modern car. The driver is actually interacting with a distributed computing system on wheels. With up to 100 electronic control units and hundred of millions of lines of code, the modern automotive industry has become more about software than mechanics and aerodynamics. And yet, we think and interact with our car as we would have done in 1991. Or think at our symbiotic relationship with social media as experienced via our personal data capturing device: the smartphone. It is symbiotic because it satisfies the human need for emotional connectedness while it feeds content to the social media infrastructure, content that is essential for its existence and that is typically metabolized as targeted advertisement. The modern human being has feelings relatable to gymnophobia whenever leaving home without the smart phone, a fear of a sensation of nakedness, incompleteness that transcends the rational. And dually we accept any other human being we are close to or even interacting with to be concurrently doing something on their smart phone. The phone is such an integral and accepted part of who we are and how we behave that we can agree that Mark Weiser’s prediction was correct: phones are our everyday life and we do not even notice anymore. In many countries the level of penetration of mobile phones is above 80%, including population of any age (Statista (2022)). The number of active phone subscriptions is higher than 7 billion. If we consider Bluetooth, a technology often used for dynamic connectivity at the edge of the system, 4 billion Bluetooth Low Energy network interfaces are currently been shipped per year (Bluetooth SIG (2021)). Number projected to surpass 6 billions by 2025. And more generally, the predictions indicate that by 2030 the total amount of IoT devices worldwide, of any type, will reach the value of 24 billion (Transforma Insights (2020)).

As a popular technology in the information age, Internet of Things (IoT) can collect various types of information in real time, realize the ubiquitous connection between things and people, and process the intelligent perception, identification, and management of things, processes, and information, and environment protection through various network access methods. Applying IoT to various fields is like wrapping the Earth with a layer of “digital skin” (Gubbi et al., 2013; Bauwens et al., 2020; Li and Da Xu, 2020). Moreover, under the trend of global warming, the emergence of the theme of Energy Saving and Emission Reduction (ESER) undoubtedly poses new challenges to the development of IoT. When IoT is widely used in various life scenarios, its main purpose is to provide intelligent services and environments. IoT applications can connect any sensing device to the Internet for data transmission, so as to realize intelligent identification, tracking, positioning, and monitoring of sensing devices. In addition, IoT contains many types ofWireless Sensor Networks (WSN), which, as a part of IoT sensing layer, can meet the actual needs of people to obtain reliable data in special environments (Sadowski and Spachos, 2020). WSN is a multi-hop network which is self-organized by many sensor nodes. It has the characteristics of flexibility, fault tolerance, high awareness, low cost, strong survivability, and fast layout. Therefore, IoT has a wide range of applications, such as environmental monitoring, agriculture, military, and medical care, and can collect, process, and disseminate collected data deployed in various environments (Aman et al., 2020; Fortino et al., 2020). However, for some special scenes, many sensor nodes are often placed in areas that cannot be accessed by human beings. While enjoying the convenience brought by WSN, people are also faced with the problems that illegal personnel obtain illegitimate interests by intercepting the monitoring data transmitted in the public channel. Therefore, the attention to security issues in IoT cannot be ignored. With the increasing commercial scope of 5th Generation Mobile Communication Technology (5G) communication technology in cities, the application of IoT in power, construction, industry, intelligent transportation, agriculture, logistics, intelligence, high efficiency, and ESER is being promoted (Verma et al., 2020). Of course, applying IoT is also inseparable from the combination of 5G communication, Cloud Computing (CC), Edge Computing (EC), blockchain, AI, and other technologies. IoT can collect many data from the environment, effectively monitor, analyze, and manage energy consumption, and reasonably improve IoT by identifying and analyzing opportunities of energy efficiency improvement (Khan et al., 2020; Liao et al., 2020; Saračević et al., 2020).

It is also widely recognized that these devices should well collaborate with each other. This also catalyses the birth of Internet-of-Things (IoT) Hassan. (2019). IoT allows various devices, such as sensors, actuators, smart phones, and any smart devices, to connect with each other via the network, and to work together for providing better services eventually. Thanks to the fast development in the last decades, IoT has been applied in various aspects successfully, i.e., smart home Yang et al. (2018), smart city Kim et al. (2017) and smart health Sun et al. (2020), greatly reshaping our society. As communication is the core to realize collaboration, the communication and networking protocol plays a critical role in implementing an IoT system. As already widely discussed, due to the limitation of size, power and computation capability, traditional Internet oriented communication and networking protocols are not quite suitable to IoT. To this end, many protocols, such as Bluetooth Low Energy, ZigBee, Lora, NB-IoT, CoAP, 6LoWPAN, MQTT, have been proposed with different characteristics (e.g., power consumption, transmission rate, transmission range, etc.,) and application domains Dizdarević et al. (2019). In addition, the recent 5G, B5G, and 6G networks are also well known for their special support to IoT communications. Besides, Artificial Intelligence (AI) technology also become an essential part of IoT systems. Besides exploring AI technology to process the IoT data, the system could be also manipulated by AI for autonomous performance or resource efficiency optimization. Recognizing the fact that one protocol may not fit for all scenarios, the coordination and the compatibility between different protocols thus become critical issues. Besides, various IoT applications also urge us to optimize the communication and network protocols to satisfy diverse Quality-of-Experience (QoE). Therefore, in the past decades, many efforts has been devoted to optimizing the IoT communication and networking protocols from various aspects. Nonetheless, with the emergence of new technologies (e.g., Software Define Networking, backscatter communications, Blockchain), new trend (e.g., in-network computing), new applications (e.g., autonomous driving), the protocol design is still a hot topic as it still confronts many challenges. As a result, in this article, we will discuss the main challenges imposed by these new technologies, concept, and trends to the design of IoT communication and networking protocols.

Numerous approaches to data collection and analysis have been covered, some of which use active sensing equipment, while others rely on passive probing, which takes advantage of nearly universal smartphone usage and WiFi network coverage. In this study, we introduce a system that uses WiFi probing technologies aimed at tracking user locations and understanding individual behavior. We built our own devices to passively capture WiFi request probe packets from smartphones, without the phones being connected to the network.
