The low-power wide-area network (LPWAN) paradigm is gradually gaining market acceptance. In particular, three prominent LPWAN technologies are emerging at the moment: LoRaWAN™ and SigFox™, which operate on unlicensed frequency bands, and NB-IoT, operating on licensed frequency bands. This paper deals with LoRaWAN™, and has the aim of describing a particularly interesting feature provided by the latest LoRaWAN™ specification—often neglected in the literature—i.e., the roaming capability between different operators of LoRaWAN™ networks, across the same country or even different countries. Recalling that LoRaWAN™ devices do not have a subscriber identification module (SIM) like cellular network terminals, at a first glance the implementation of roaming in LoRaWAN™ networks could seem intricate. The contribution of this paper consists in explaining the principles behind the implementation of a global LoRaWAN network, with particular focus on how to cope with the lack of the SIM in the architecture and how to realize roaming.

Abstrak: Meningkatnya penggunaan internet di dunia, membuat trafik internet menjadi tinggi. Kebutuhan akan interkoneksi antar jaringan yang meningkat terutama pada perusahaan yang mempunyai banyak cabang. Oleh karena itu perusahaan dituntut untuk mengeluarkan budget lebih banyak lagi. Untuk meredam pengeluaran yang terlalu berlebih maka dibutuhkan dibutuhkan sebuah jaringan Virtual Private Network (VPN). Dengan memanfaatkan Open VPN-Access Server biaya yang dikeluarkan lebih murah dibandingkan dengan sewa VPN-IP yang relatif lebih mahal biayanya. Untuk jaringan yang lebih baik, maka harus ditopang dengan struktur topology terbaik menurut pemasangannya. Pemilihan topology pada awal pembangunan jaringan sangat penting untuk membuat akses Virtual Private Network (VPN) ini terkoneksi dengan baik.   Kata kunci: VPN, Jaringan, Open VPN-Acces Server.   Abstract: The increasing use of the internet in the world, making internet traffic become high. The need for interconnection between networks is increasing in companies with many branches. Therefore companies are required to spend even more budget. To reduce excess expenditure, a Virtual Private Network (VPN) is needed. By utilizing Open VPN-Server Access that is issued is cheaper compared to VPN-IP leases that are relatively more expensive. For better tissue, it must be supported by the best topological structure according to installation. The choice of topology at the beginning of network development is very important to make this Virtual Private Network (VPN) access well connected.   Keywords: VPN, Networking, Open VPN-Acces Server.

With the advent of the Internet of Things (IoT) era, we are experiencing rapid technological progress. Billions of devices are connected to each other, and our homes, cities, hospitals, and schools are getting smarter and smarter. However, to realize the IoT, several challenging issues such as connecting resource-constrained devices to the Internet must be resolved. Recently introduced Low Power Wide Area Network (LPWAN) technologies have been devised to resolve this issue. Among many LPWAN candidates, the Long Range (LoRa) is one of the most promising technologies. The Long Range Wide Area Network (LoRaWAN) is a communication protocol for LoRa that provides basic security mechanisms. However, some security loopholes exist in LoRaWAN’s key update and session key generation. In this paper, we propose a dual key-based activation scheme for LoRaWAN. It resolves the problem of key updates not being fully supported. In addition, our scheme facilitates each layer in generating its own session key directly, which ensures the independence of all layers. Real-world experimental results compared with the original scheme show that the proposed scheme is totally feasible in terms of delay and battery consumption.

The internet of things (IoT) brings ‘life' to non-living things. In the IoT frameworks, the devices become smarter, more intelligent, become able to make decisions, and can communicate with other entities, applications, as well as human beings. According to a Gartner report, by 2020 more than 25 billion devices will be connected to the internet. Low power wireless wide area network (LPWAN) is a group of various low power, wide-area technologies such as LoRa, Sigfox, NB-IoT, DASH7, RPMA, LTE-M, designed to interconnect low bandwidth, battery-operated devices having limited processing power, limited memory, transmission speed with low bit rates at long-range using radio communication technologies. Most of these technologies provide a long battery life, low deployment cost, large capacity, and generates deeper insights of businesses. However, each technology differs in latency, data rate, handover mechanisms, quality of services, applications, and use cases. In this chapter, the authors provide the basic principles of these LPWANs and present their applications in different domains.

The Internet Of Things

The Internet of Things (IoT) is an emerging paradigm that enables many beneficial and prospective application areas, such as smart metering, smart homes, smart industries, and smart city architectures, to name but a few. These application areas typically comprise end nodes and gateways that are often interconnected by low power wide area network (LPWAN) technologies, which provide low power consumption rates to elongate the battery lifetimes of end nodes, low IoT device development/purchasing costs, long transmission range, and increased scalability, albeit at low data rates. However, most LPWAN technologies are often confronted with a number of physical (PHY) layer challenges, including increased interference, spectral inefficiency, and/or low data rates for which cognitive radio (CR), being a predominantly PHY layer solution, suffices as a potential solution. Consequently, in this article, we survey the potentials of integrating CR in LPWAN for IoT-based applications. First, we present and discuss a detailed list of different state-of-the-art LPWAN technologies; we summarize the most recent LPWAN standardization bodies, alliances, and consortia while emphasizing their disposition towards the integration of CR in LPWAN. We then highlight the concept of CR in LPWAN via a PHY-layer front-end model and discuss the benefits of CR-LPWAN for IoT applications. A number of research challenges and future directions are also presented. This article aims to provide a unique and holistic overview of CR in LPWAN with the intention of emphasizing its potential benefits.

In this chapter, we will also discuss the network implementation issues of large computer labs. For a large computer lab, multiple medium online computer labs are connected through a wide area network (WAN) or through the Internet. For this type of network, the network developing process often involves outside companies such as a telephone company and a technology consulting company.
