Abstract In brownfields, controlling well integrity is critical in maintaining production and ensuring safety of the personnel and infrastructures. Equally important is optimizing and allocating production in wells by closely following wellhead upstream pressures (and temperatures). In the current situation, field crews have to move from well to well. This method is time consuming, exposes personnel to driving hazards and potentially dangerous areas. In addition, human reading of manual pressure gauges can result in large discrepancy in the reported values. Together with the low frequency of manual readings, this method does not allow for pro-active well intervention and can result in higher downtime in case of well tripping. Deploying remote monitoring with classical telemetry in fields with limited telecommunication infrastructure is costly and complex. Low Range Wide Area Network (LoRaWAN), a public wireless network technology developed in 2009, changes the situation. It enables low power compact battery sensors with up to 10 km radio range. This performance is sufficient to connect, in one go, most onshore wells without power nor connectivity. This paper describes a pilot project to evaluate the adequacy of this technology in ADNOC Onshore fields. The objective is to assess performance of LoRaWAN deployed Sensors along four metrics: deployment time, deployment cost, Base station radio coverage and data availability. The pilot uses a plug-in ATEX- certified Wireless Pressure and Temperature (P&T) sensors developed by the vendor SRETT, commercial LoRaWAN Base stations, and proprietary software to provide remote access to the data via cloud data storage and web based application. For this pilot, four Base stations were deployed in two giant oil fields collecting data from four well heads each equipped with two sensors (P&T). This combination allowed testing wireless link quality over eight radio paths, some with terrain obstacles between Sensors and Base stations. The complete system was fully tested and validated at the shop prior to field deployment. Performances during the deployment was evaluated, and Sensor behaviors were monitored over a three-month period. In the current environment, maintaining a high HSE standard on aging infrastructure must be made at a controlled cost. LoRaWAN IoT remote monitoring technology is cost effective and efficient to deploy. Once deployed, it will enable preventative safe detection of wells with potential issues, improved accuracy and understanding of production events and lead to a reduction of potential adverse situations thanks to an optimized intervention strategy.

Low Power Wide Area Network (LPWAN) technologies provide long-range and low power consumption for many battery-powered devices used in Internet of Things (IoT). One of the most utilized LPWAN technologies is LoRaWAN (Long Range WAN) with over 700 million connections expected by the year 2023. LoraWAN base stations need to ensure stable and energy-efficient communication without unnecessary repetitions with sufficient range coverage and good capacity. To meet these requirements, a simple and efficient upgrade in the design of LoRaWAN base station is proposed, based on using two or more concentrators. The development steps are outlined in this paper and the evaluation of the enhanced base station is done with a series of measurements conducted in Zagreb, Croatia. Through these measurements we compared received messages and communication parameters on novel and standard base stations. The results showed a significant increase in the probability of successful reception of messages on the novel base station which corresponds to the increase of base station capacity and can be very beneficial for the energy consumption of most LoRaWAN end devices.

This paper shows the vulnerabilities present in a wireless sensor network implemented over a long-range wide area network (LoRaWAN) LoRaWAN, and identifies possible attacks that could be made to the network using sniffing and/or replay. Attacks on the network were performed by implementing a protocol analyzer (Sniffer) to capture packets. The Sniffer was implemented using the RTL2832U hardware and visualized in Wireshark, through GNU-Radio. Tests showed that data availability and confidentiality could be threatened through replay attacks with LoRa server verification using HackRF One and GNU-Radio hardware. Although the LoRaWAN specification has, frame counters to avoid replay attacks, under given the right conditions, this measure could be violated even deny service to the node on the server.

This work centres on the study of campus wifi hotspot networks in Nigeria universities, using the Nnamdi Azikiwe University Awka as a case study. A Campus Wide Area Network (CWN) provides a means of communication and collaboration in data intensive environments. These are vital key factors to building a strong knowledge culture and facilitating collaborative research for any educational institution. Network stumbler (Wifi Network Analyzer) and Iperf were installed on different laptop computers in the respective Access Points (AP) while being monitored from a dedicated server running on Mikrotik and wireshark. This was used in collecting useful data needed for the characterisation of the UNIZIK wifi hotspot network in terms of Received signal strength index (RSSI), Data throughput and latency/network delay. The AP distance from user is carefully measured with a meter tape. Performance analysis carried out on this university wifi hotspots shows that the network offers a delay of 0.1545s by default that increases by a factor of 0.001s; a data throughput of 37.30Mbps that decreases by a factor of 0.25Mbps for any user added to the network. Also, that an RSSI of -35.438dBm was obtained at the AP base station which decreases by a factor of 0.4925dBm for any 1m distance away from the APand finally that a traditional hotspot networks based on IEEE 802.11 series lacks integrated intelligence for services convergence, QoS performance and in most cases suffers from interoperability problem

Despite the fact that a large number of web applications are used in the medical community, there are still certain technological challenges that need to be addressed, for example, browser plug-ins and efficient 3D visualization. These problems make it necessary for a specific browser plug-in to be preinstalled on the client side when launching applications. Otherwise, the applications fail to run due to the lack of the required software. This paper presents the latest techniques in hypertext markup language 5 (HTML5) and web graphics library (WebGL) for solving these problems and an evaluation of the suitability of the combination of HTML5 and WebGL for the development of web-based medical imaging applications. In this study, a comprehensive medical imaging application was developed using HTML5 and WebGL. This application connects to the medical image server, runs on a standard personal computer (PC), and is easily accessible via a standard web browser. The several functions required for radiological interpretation were implemented, for example, navigation, magnification, windowing, and fly-through. The HTML5-based medical imaging application was tested on major browsers and different operating systems over a local area network (LAN) and a wide area network (WAN). The experimental results revealed that this application successfully performed two-dimensional (2D) and three-dimensional (3D) functions on different PCs over the LAN and WAN. Moreover, it demonstrated an excellent performance for remote access users, especially over a short time period for 3D visualization and a real-time fly-through navigation. The results of the study demonstrate that HTML5 and WebGL combination is suitable for the development of medical imaging applications. Moreover, the advantages and limitations of these technologies are discussed in this paper.

We introduce PANEL a position-based aggregator node election protocol for wireless sensor networks. The novelty of PANEL with respect to other aggregator node election protocols is that it supports asynchronous sensor network applications where the sensor readings are fetched by the base stations after some delay. In particular, the motivation for the design of PANEL was to support reliable and persistent data storage applications, such as TinyPEDS; see the study by Girao et al. (2007). PANEL ensures load balancing, and it supports intra and intercluster routing allowing sensor-to-aggregator, aggregator-to-aggregator, base station-to-aggregator, and aggregator to-base station communications. We also compare PANEL with HEED; see the study by Younis and Fahmy (2004) in the simulation environment provided by TOSSIM, and show that, on one hand, PANEL creates more cohesive clusters than HEED, and, on the other hand, that PANEL is more energy efficient than HEED.

The report compares LPWAN (low-power, wide-area network) and MEC (Multi-access edge computing) topologies, examines opportunities to achieve lower latency in LPWAN networks by integrating their architecture with the MEC paradigm. LPWAN networks are highly suitable to be combined with a MEC architecture. The radio-access equipment place,e.g., base station, gateway, etc., is a main location to run delay-sensitive applications, processing/storage offloading tasks, or hosting those services that need in real-time information from the RAN (Radio Access Network). For that reason, this places in the network has been identified as ideal for installing the MEC equipment.The four-tier architecture of LPWAN and MEC are kept, so they perfectly match with each other.

Dalam dunia bisnis, biasanya sebuah organisasi ingin membangun Wide Area Network (WAN) untuk menghubungkan beberapa kantor cabangnya. Sebelum munculnya Virtual Private Network (VPN), mereka umumnya menggunakan ” leased line” yang mahal sehingga hanya perusahaan besar yang dapat memilikinya.VPN - WAN memberi solusi alternatif karena dapat mengurangi biaya pembuatan infrastruktur jaringan dan memotong biaya operasional dengan memanfaatkan failitas internet sebagai media komunikasinya. Perusahaan cukup menghubungi Internet Service Provider (ISP) terdekat untuk mendapatkan layanan ini.Setiap paket informasi yang dikirim dapat diakses, diawasi atau bahkan dimanipulasi oleh pengguna. Supaya komunikasi berjalan aman maka diperlukan protokol tambahan khusus yang dirancang untuk mengamankan data yang dikirim. Dewasa ini sudah banyak perusahaan seperti : perusahaan manufaktur, distribusi dan retail; pertambangan minyak dan gas, telekomunikasi, finansial, pemerintahan serta industri transportasi yang menggunakan VPN karena fasilitas –fasilitas yang ditawarkan berupa remote access client, internetworking LAN to LAN serta akses yang terkontrol dengan biaya yang murah. Uji coba yang dilakukan Miercom(LAB penyedia testing kinerja perangkat keras) terhadap Cisco 1841 membuktikan bahwa Cisco 1841 dapat menopang suatu komunikasi dua arah, interkoneksi IP WAN kapasitas E1 dengan enkripsi 3DES yang dapat menunjang throughput sampai dengan 2 Mbps dalam koneksi E1 IP-WAN. Penggunaan VPN akan meningkatkan efektivitas, efisiensi kerja serta skalabilitas perusahaan. Keuntungan lain yang didapat dari VPN adalah pada biaya pulsa yang jauh lebih murah dibandingkan dengan menggunakan” leased line”.

We are now living in the era of big data. The large volume of data raises a lot of issues related to data storage and management, stimulating the emergence of Cloud storage. Unlike traditional storage systems such as SAN (Storage Area Network) and NAS (Network Attached Storage), Cloud storage is delivered over a network and has such features as easy to scale and easy to manage. With Cloud storage shielding complex technical details such as storage capacity, data location, data availability, reliability and security, users can then concentrate on their business rather than IT (Information Technology) system maintenance. However, it is not an easy task to develop a Cloud storage system because multiple factors are involved. In this chapter, the authors show their experience in the design and implementation of a Cloud storage system. They detail its key components, namely the distributed file system Carrier and the data sharing service Corsair. A case study is also given on its application at Tsinghua University.
