We investigate the connection between the autonomic nervous system and the voice in patients with vocal hyperfunction and healthy-control groups. We present a methodology and preliminary results of two multi-modal measurement streams that capture this relationship. Subjects were instrumented for daily, ambulatory collection of their voice and wrist-based electrodermal activity. Measures of vocal function (e.g., fundamental frequency) were computed, as well as measures of autonomic function (e.g., skin conductance response). Spearman correlation coefficients were calculated to measure the relationship between vocal and autonomic function over sliding windows throughout each observation day. We found preliminary evidence that patients with a subtype of vocal hyperfunction (non-phonotraumatic vocal hyperfunction) exhibit a coupling between the autonomic nervous system and the vocal system. Understanding how the autonomic nervous system interacts with the voice may provide new insights into the etiology/pathophysiology of vocal hyperfunction and improve prevention, diagnosis and treatment of these disorders.

Sensors constitute information providers which are subject to imperfections and assessing the quality of their outputs, in particular the trust that can be put in them, is a crucial task. Indeed, timely recognising a low-trust sensor output can greatly improve the decision making process at the fusion level, help solving safety issues and avoiding expensive operations such as either unnecessary or delayed maintenance. In this framework, this paper considers the question of trust dynamics, i.e. its temporal evolution with respect to the information flow. The goal is to increase the user understanding of the trust computation model, as well as to give hints about how to refine the model and set its parameters according to specific needs. Considering a trust computation model based on three dimensions, namely reliability, likelihood and credibility, the paper proposes a protocol for the evaluation of the scoring method, in the case when no ground truth is available, using realistic simulated data to analyse the trust evolution at the local level of a single sensor. After a visual and formal analysis, the scoring method is applied to real data at a global level to observe interactions and dependencies among

Herein, we present a localization method for swarm robot systems that relies solely on measured distances from surrounding robots. Using the sensor fusion technique, an exteroceptive estimation method based on the measured distance is dynamically coupled with a simple proprioceptive estimation that uses a robot’s own dynamical properties. Our method strictly preserves the locality of algorithm. The results of numerical simulations for several scenarios show that our proposed method is more accurate that conventional methods.

Simulation models allow predicting the development of real situations in various technical, business and social systems. However, many real situations in business environment are of bursty nature. Buyers often appear concentrated or, in other words, bursty. Different approaches for analysing buyers’ behaviour have been developed. One of these approaches focuses on analysis of gaps between buyers, and the buyers’ scenario is completely described by the sequence of gaps. The present research is interdisciplinary, namely telecommunications and business management. The methodology of the present contribution is built on adaptation of gap distribution functions from data transmission theory in telecommunications to bursty business process in business management. The aim of the paper is to demonstrate inter-connections between different gap distribution functions such as Weibull, Exponential and Wilhelm as well as to compare different gap distribution functions for their suitability when analysing bursty processes. Furthermore, this contribution provides the mathematical description of gap processes. The comparison results of different gap distribution functions are presented. The theoretical results are confirmed by practical implementation in agent-based simulation environment.

Radio Frequency-Energy Harvesting (RF-EH) system usually incorporates ‘harvest-store-use’ mechanism, i.e. the harvested RF energy is first stored in an energy buffer and when the stored energy level is sufficient enough to power an application it is then supplied to the device. To improve the network’s performance in terms of lifetime and buffer capacity, it is crucial to develop a model for RF powered Wireless Sensor Networks (WSNs), which considers source-load relations, buffer size and ambient conditions within the context of Energy Neutral Operation (ENO) and minimum energy wastage. In this paper, we propose a model for RF powered WSNs that makes use of available RF energy with variations in maximum and minimum energy levels for two different worst case scenarios encompassing ENO and buffer requirements. We develop an algorithm based on the proposed model to find the optimum energy consumption rate of each sensor nodes that would ensure maximum lifetime of the WSN with minimum buffer capacity. We verified our approach by comparing the results with all other possible consumption rates. We also performed a comparative analysis to find the effect of available RF energy fluctuation in the individual sensor nodes’ lifetime.

The exponential growth of wireless-based solutions, such as those related to the mobile smart devices (e.g., smart-phones and tablets) and Internet of Things (IoT) devices, has lead to countless advantages in every area of our society. Such a scenario has transformed the world a few decades back, dominated by latency, into a new world based on an efficient real-time interaction paradigm. Recently, cryptocurrency has contributed to this technological revolution, whose fulcrum is a decentralization model and a certification function offered by the so-called blockchain infrastructure, which makes it possible to certify the financial transactions, anonymously. This paper aims to indicate a possible approach able to exploit this challenging scenario synergistically by introducing a novel blockchain-based distributed paradigm for data exchange between wireless-based devices defined Internet of Entities (IoE). It is based on two core elements with interchangeable roles, entities and trackers, which can be implemented by using existing infrastructures and devices, such as those related to smart-phones, tablets, and IoT systems. The employment of the blockchain-based distributed paradigm allows our approach ensuring the anonymization and immutability of the involved data, which is key in many scenarios and domains (e.g. financial applications, health and legal applications dealing with personal and sensitive data), requirements more and more searched in recent innovations. The possibility to exchange data among a huge number of devices gives rise to a novel and widely exploitable data environment, whose applications are possible in different domains, such as, in Security, eHealth, and Smart Cities.

The design of Medium Access Control (MAC) protocols for UWSNs poses many challenges because of their long propagation delay, high mobility, limited bandwidth, and high bit error rate. Due to these unique acoustic channel characteristics, most contention-based MAC protocols are costly. Thus, collisions and retransmissions should be efficiently handled at the MAC layer in order to reduce the energy cost and to improve throughput and fairness across the network. As a consequence, they do not perform as efficiently as their achieved performance in terrestrial networks. In this paper, we evaluate the performance of three recently reported distributed collision-free MAC protocols; namely, ED-MAC, DL-MAC, and GC-MAC under various operational conditions. An extensive simulation study is carried out to compare the performance of these MAC protocols in terms of packet delivery ratio (PDR), throughput, and energy consumption with different scenarios (narrow and shallow networks) under varying traffic rates and numbers of nodes. Our study results showed that ED-MAC reaches the best energy efficiency in a narrow scenario with a light load than DL-MAC and GC-MAC protocols. While DL-MAC is a suitable choice for both scenarios among others in terms of flexibility. In terms of reliability and scalability, GC-MAC achieves the best performance in both scenarios than other protocols.

Nowadays, wireless indoor positioning systems have become very familiar, and widespread all over the world. They are successfully used in many applications including tracking objects e.g. Firemen who usually face life-threatening situations. Indoor positioning systems become critically convenient in such scenarios. This paper deals with the tracking of a group of firemen during their mission in order to have a real-time visibility of their coordinates. These firemen are armed by smart sensors and are, at the same time, active in a smart environment containing referenced nodes. This paper will propose two approaches: ‘Centralized Emission’, and ‘Broadcast Emission’ and will describe the proposed method to calculate the firemen’s coordinates.

Despite the worldwide use of stranded Unshielded Twisted Pair (UTP) cables, scientific references dealing with accurate calculation of distributed parameters of such transmission lines are generally missing, especially in high frequency applications where skin and proximity effects are present. On the other hand, reflectometry is a high frequency method that relies on wave propagation in a cable under test for fault diagnosis. In this context, this paper proposes a distributed parameters model for the lossy transmission line of a stranded UTP cable including the pitch of twist and frequency dependent effects to evaluate as faithfully as possible the reflectometry response in such cables. The developed model is validated with 3D-electromagnetic simulations using Time Domain Reflectometry (TDR). For online diagnosis, Orthognal Multi-Tone Time Domain Reflectometry is performed thanks to its capacity to control bandwidth and enable sensors fusion. In complex wiring networks, the developed model is performed to evaluate the performance of OMTDR-based diagnosis sensor including a Xilinx Zynq 7010 FPGA, 10-bit Analog-to-Digital Converter (ADC) and Digital-to-Analog Converter (DAC).

Collaborative Body Sensor Networks (CBSNs) are collection of Body Sensor Networks that move in a given area and collaborate, interact and exchange data between each other to identify group activity, perceive events detected by group of individuals, and monitor the status of single and multiple persons. Even though some routing algorithms were proposed for Wireless Sensor Networks (WSNs) and Body Sensor Networks (BSNs), very few studies were found to cover routing in CBSNs. In this paper, we propose a robust cluster based scheme that increases the routing efficiency through the three steps of the routing process: cluster formation, cluster head election, and routing operation of data to the Base Station (BS). MATLAB simulations are performed to compare the performance of the proposed algorithm to other existing routing schemes. Results show that the proposed scheme outperforms others in terms of delay, energy consumption, and packet drop percentage, and therefore succeeds in addressing CBSN challenges.
