Title:

Design of an Energy-efficient Hybrid UWB-RF Indoor Distance Estimation System

Abstract: Wireless Sensor Network (WSN) plays a significant role in modern applications by offering different services, including state machines monitoring, predictive maintenance, and vehicle/store tracking. In such applications, it is crucial to apply localization methods to identify the current location of sensor nodes with high accuracy. Due to the energy constraint of sensor nodes, the energy consumption needs to be highly considered while performing the localization process. In this regard, this paper aims to design an energy-efficient and accurate localization system. Therefore, a novel hybrid solution is designed involving the Ultra Wide Band (UWB) technology and Radio Frequency (RF) transceiver. The UWB is based on Decawave’s DWM1000 transceiver, which provides accurate distance measurements with a high power consumption. To reduce the power consumption, the data transmission between nodes is performed by the low-power RF transceiver. Using this architecture, the experimental validation shows a good performance in both power consumption and accuracy. The system’s overall power consumption is reduced as well as a 10-centimeter accuracy level is achieved.

Title:

Abstract: Localization is an essential feature in numerous Wireless Sensor Network (WSN) applications, including tracking, health monitoring, and military supervision. Analytical modeling and analysis of the localization system remain challenging and infeasible since it offers oversimplified results with limited reliability to the evaluated cases. Likewise, disseminating test-beds involves a lot of effort, making the simulation phase indispensable to study the WSN localization. The defined localization model needs to ensure solid and pragmatic network assumptions during the simulation. However, most network simulators don’t meet specific criteria related to network definition, such as scalability and heterogeneity. As part of this endeavor, a guideline for evaluating and analyzing technical methods of range-based localization is developed. Multiple linear regression is used to generate the different localization instances, which enables to support different and non-dependent parameters. The developed guideline for range-based localization is tested and validated for existing localization solutions.

Title:

A Compact Receiving Side Circuit for Wireless Power Transfer with Foreign Object Detection Technique

Authors:

Abdallah Adawy, Ghada Bouattour, Yingjie Yuan, Mohammed Ibbini and Olfa Kanoun

Abstract: Wireless power transfer is a promising technology, it is used to overcome the problems of conductive power transfer. However, numerous challenges still face this technology, especially in security issues. Detecting any foreign object in the proximity of the transmitter will save power and secure the system from any possible dangers. In this paper, A compact semi-active rectifier is proposed to detect foreign objects by applying the proposed control technique without extra components and also to control the charging process of the supercapacitor efficiently. Two different modes are proposed in this work to optimize power consumption. The low-power mode is used in the case of no receiver in the power transfer range or when a foreign object is detected, so the primary side controller adjusts the input voltage of the system to optimize the power consumption. Otherwise, it works in the power transfer mode at the resonance frequency.

Title:

Appropriate Integration of Wake-up Receivers in Simulations Tools based on Real Experiments

Authors:

Amina Whichi, Robert Fromm, Ahmed Fakhfakh and Faouzi Derbel

Abstract: Wireless Sensor Networks (WSNs) are an emerging and promising approach to Internet of Things (IoT). However, energy consumption is regarded as one of the most critical problems in WSNs due to the devices’ limits.To address this problem, an ultra-low-power radio receiver known as a wake-up receiver (WuRx) is used to handle idle listening while the main radio is turned off. Since simulators for performance prediction have become almost indispensable in the design and management of new hardware equipment and components, we will present in this paper the design of a wake-up receiver module, that could be a solution to the energy consumption’s challenge, in OMNeT++ and compare it to experimental results, focusing on energy performance and reliability factors.

Implementation of RSSI Module in Omnet++ for Investigation of WSN Simulations based on Real Environmental Conditions

Abstract: The simulation of different scenarios and protocols under environmental conditions is a success key for a reliable Wireless Sensor Network (WSN). For some applications, the variation of the weather conditions as the temperature and humidity could affect the Received Signal Strength Indication (RSSI). Running multi- simulation scenarios is required to evaluate the proposed protocols and architectures before their deployment in a real-world network. The more the simulator mimics the real world, the closer the evaluation results to the real network. In this paper, we have integrated temperature and humidity in the Omnet simulator and have taken into account the impact of these environmental factors on the RSSI based on real experiments that were carried out using the CC1101 radio ship of Panstamp Avr2 at 868 MHz frequency.
