    DZ50: Energy-Efficient Wireless Sensor Mote Platform for Low Data Rate Applications
    (CERIST, 2014-07-07) Ouadjaout, Abdelraouf; Lasla, Noureddine; Bagaa, Miloud; Doudou, Messaoud; Zizoua, Cherif; Kafi, Mohamed Amine; Derhab, Abdelouahid; Djenouri, Djamel; Badache, Nadjib
    A low cost and energy efficient wireless sensor mote platform for low data rate monitoring applications is presented. The new platform, named DZ50, is based on the ATmega328P micro-controller and the RFM12b transceiver, which consume very low energy in low-power mode. Considerable energy saving can be achieved by reducing the power consumption during inactive (sleep) mode, notably in low data rate applications featured by long inactive periods. Without loss of generality, spot monitoring in a Smart Parking System (SPS) and soil moisture in a Precision Irrigation System (PIS) are selected as typical representative of low data rate applications. The performance of the new platform is investigated for typical scenarios of the selected applications and compared with that of MicaZ and TelosB. Energy measurement has been carried out for different network operation states and settings, where the results reveal that the proposed platform allows to multiply the battery lifetime up to 7 times compared to MicaZ and TelosB motes in 10s sampling period scenarios.

    Electrical Energy Consumption Control in Buildings Using Wireless Sensor
    (CERIST, 2018-01-25) Djenouri, Djamel; Laidi, Roufaida; Zizoua, Cherif
    Energy consumption in residential and commercial buildings has increased dramatically worldwide in the last decade, due to the constant population and economic growth, the proliferation of electronic and consumer appliances. This has dramatic footprint on the environment in terms of carbon emission, in addition to the economic impact. Green and smart building strategies will play a pivotal role to reduce this footprint and maximize economic and environmental performance. These strategies can be integrated into buildings at any stage, from design and construction, to maintenance and renovation. The use of modern Information and Communication Technologies (ICT), notably IoT solutions, for building control is one of the promising strategies for the future. The aim of this project was to explore this domain, and as a first step to develop a wireless sensor networks based solution for monitoring and energy management in offices. A prototype has been targeted as a proof of concept where sensors monitor physical parameters in CERSIT offices (presence of people, ambient light, etc.), and accordingly actuate lighting, air conditioning, etc. This report is a short summery of the different parts developed in this project.

    On the Effect of Sensing-Holes in PIR-based Occupancy Detection Systems
    (2016-02-20) Ouadjaout, Abdelraouf; Lasla, Noureddine; Djenouri, Djamel; Zizoua, Cherif
    Sensing-holes in PIR-based motion detection systems are considered, and their impact on occupancy monitoring applications is investigated. To our knowledge, none of prior works on PIR-based systems consider the presence of these holes, which represents the major cause for low precision of such systems in environments featured with very low mobility of occupants, such as working offices. We consider optimal placement of PIRs that ensures maximum coverage in presence of holes. The problem is formulated as a mixed integer linear programming optimization problem (MILP). Based on this formulation, an experimental study on a typical working office has been carried out. The empirical results quantify the effects of the holes on the detection accuracy and demonstrate the enhancement provided by the optimal deployment of the solution.
