Anomaly Detection in Optical Links Using State of Polarization Monitoring
Aamir Gulistan (Simula Research Laboratory, Norway); Steinar Bjørnstad (Norwegian University of Science and Technology, Norway)
We have demonstrated a vibration monitoring method in optical fibers that enables early fiber breakage and eavesdropping intrusion warnings. Change in the state of polarization (SOP) is continuously monitored in a commercial Gigabit Ethernet (GbE) transmission system. The detection sensitivity of vibrations in a fiber-cord laying on a firm surface is characterized by inducing vibrations in the audio frequency range using a loudspeaker. Two examples of vibration patterns are characterized demonstrating significant differences in the patterns both in amplitude and time-domain. Directly touching the fiber, emulating work in a node room, give higher amplitude and slower variations in SOP than hammer strikes on the surface close to the fiber. Ability to differentiate signatures of SOP variations based on analyzing frequency and amplitude is discussed.

Natural disasters may compromise the wireless communications infrastructures typically used by first responders. On-demand flying networks have been investigated as a solution in the H2020 ResponDrone project to address the problem, using standard technologies such as Long Term Evolution (LTE) and Wi-Fi. In this paper, we propose and evaluate a cost-effective communications payload capable of providing LTE and Wi-Fi coverage, using Software Defined Radios (SDR) and off the shelf wireless modules, respectively. The experimental tests carried out using different SDR-based LTE frameworks show that this type of solutions still suffer from performance issues, with Wi-Fi being the only feasible solution.

Rapidly evolving, high severity hazards in the form of natural or man-induced disasters require prompt and well-planned deployment of first responders to reduce the overall disaster footprint with specific emphasis on human lives. Increased situational awareness and better common operational picture requires not only new technologies like UAVs, UGVs AR/MR glasses and other modalities to be deployed in the field but also smooth, consolidated, bidirectional, augmented information flow between first responders and command centers. RESPOND-A is a technology enhancement initiative that focuses on providing First Responders with immediate access to technological advancements during their mission by integrating innovative equipment, robust data pipelines and network services. Our approach is expected to further enhance the deployment of optimal Risk Mitigation strategies and improve mission safety by enabling pre-disaster planning tools and post-disaster performance assessment and model integration to further improve performance in similar operations.

The interest in cost-effective broadband wireless underwater communications has been motivated by practical applications demanding video collection by Autonomous Underwater Vehicles (AUVs). However, current communication technologies used in these scenarios limit underwater high definition video transfer to distances up to tens of meters.
In this paper we propose a new solution capable of performing adaptive and reliable high definition video streaming for distances in the order of kilometers, taking advantage of data mules.
Experimental results show the proposed solution enables video streaming for long distances with a reasonable first byte delay and continuous video delivery after just two Round-trip Times.

The COVID-19 pandemic and the need for self-isolation has decreased the frequency of visits to senior citizens by family members or caregivers. Because of this, many health concerns of the elderly remained unresolved. We created a IoT system, called Zelar@CB, that monitors the daily activities of isolated elderly people who do not have access to at-home care. The proposed project detects unusual activity by monitoring the person’s usage of electrical appliances to track if the user left the stove on or if there is a change in usage. It can also detect when the user falls, and sends an alert to family members or caregivers.

The demand for various smart applications in the Internet of Things (IoT) domain is overgrowing. These applications require access to the sensor data generated from different IoT applications. This IoT ecosystem needs a way for sensors and devices to make monetary transactions in exchange for these data services. This has given rise to the concept of IoT marketplaces that enables IoT sensors and devices to make monetary transactions in exchange for data. However, realizing IoT marketplaces comes with a number of challenges in several aspects ranging from data security, interoperability, and anonymity. Blockchain is identified as a suitable solution to overcome the challenges related to realizing IoT marketplaces. This paper discusses several IoT marketplace applications and presents the challenges in developing IoT marketplaces. Furthermore, possible blockchain solutions to overcome these challenges are also presented, paving the path towards blockchain-based IoT market places which enable the data suppliers (IoT sensors) and data consumers (IoT application owners) to trade seamlessly.

Connectivity plays a major role in the Internet of Things (IoT) applications. Smart asset monitoring system is an IoT application which is essential in current Covid-19 situation to handle logistics solutions. In this paper, we provide a comprehensive survey on how the emerging technologies in terms of battery lifetime, cost, and range can provide the optimal solution to monitor the assets in the supply chain after scrutinizing their benefits surpassing the existing techniques. This paper introduces a low-cost Narrowband (NB)-IoT infrastructure with GSM for optimizing data transfer that allows to receive information about real time positioning and monitoring of assets inside warehouses and movable containers. We present a Wireless Sensor Network (WSN) to gather assets data such as temperature, humidity, tilt, and other parameters and monitor them in real time. Additionally, we suggest some energy harvesting methods to control fast battery drain. The basic digital twin artificial intelligence is also used with a machine learning algorithm for predictive modelling, where the data are fed to a cloud-based platform and delivered either via mobile apps or web portals.

While recent years have witnessed a tremendous growth in the number of IoT sensors, energy poverty still remain as one of the longstanding issues for various IoT applications, especially digital healthcare and in-home health monitoring operations. To resolve the issue, we propose a technique of sampling period control in this paper. As a first step, we analyze the human behavioral pattern through historical information and subsequently model a Gaussian distribution with respect to data reliability for each sampling period to conserve energy of the sensor. Numerical results in terms of both energy reduction and data reliability are presented to validate the merits of our proposed approach.
