Item Environmentally powered multiparametric wireless sensor node for air quality diagnostic(M Y U Scientific Publishing Division, 2015) Touati, Farid; Legena, Claudio; Galli, Alessio; Crescini, Damiano; Mnaouer, Adel BenSensor networks dedicated to environmental monitoring have helped in the analysis of primal processes and have also provided vital hazard early warnings. At the same time, environmental energy is now becoming a popular workable energy source dedicated to embedded and wireless computing systems where manual recharging and/or replacement of hundreds or even thousands of batteries on a regular basis is not practical. In this paper, we present a sensor node (SENNO), a multiparametric sensor node that intelligently manages energy transfer for perpetual operation without human intervention during air quality monitoring. The overall system design and experimental results are presented together with energy budget allocation. Preliminary results demonstrate that, after a tailored calibration process, the presented platform could effectively report and trace air quality levels in a type of "set and forget" scenario.Item Review - Challenges of mobility aware MAC protocols in WSN(Institute of Electrical and Electronics Engineers Inc., 2018) Sudheendran, Sijo; Bouachir, Ons; Moussa, Sherif; Dahmane, Adel OmarIn today's smart world WSN plays an important role in IoT. The WSN nodes can be used for wildlife, patient, air quality monitoring. WSN consists of numerous sensor nodes that are connected to each other. One of the major concerns of WSN is the mobility of nodes. The mobility of the nodes creates concern to the MAC protocols that's defined for WSN static nodes. Mobile-WSN demands the participated nodes to send packets with a bursty traffic, low energy consumption and reliable connection. MAC protocol is the most important in designing the WSN as MAC plays an important role regarding throughput, mobility, security and energy consumption. This paper gives a review on mobility aware protocols such as M-MAC, MA-MAC, MMH-MAC, M-Contiki, MobiIQ, MobiDisc. © 2018 IEEE.Item A smart rig for calibration of gas sensor nodes: Test and deployment(Institute of Electrical and Electronics Engineers Inc., 2020-06) Abdaoui, Abderrazak; Touati, Farid; Tariq, Hasan; Mnaouer, Adel BenNowadays, large number of sensors are deployed and used for air quality monitoring or in some industries that process hazardous gases. These sensors need periodic calibration to ensure reliable measurements. This paper proposes a dedicated smart calibration rig with a set of novel features enabling complete automation and parallel or batch calibration. The calibration process is completely automated by developing a LabVIEW-based platform that controls the calibration environment for the sensor nodes under test by logging sensor data, generates an updated calibration equation and uploading it to the sensor node for next deployments. The results demonstrate the effectiveness of the sensor calibration rig. © 2020 IEEE.
