Numerical technologies for plant Industry
Sensor networks and crop farming systems
Kun-Mean HOU, ISIMA
In recent decades the advances are extremely important in the field of Wireless Sensor Network ‘WSN’ and Internet of Things ‘IoT’. However, the use of these new technologies is still limited because many problems are still unresolved such as cost, lack of robustness and difficulty of deploying a complete infrastructure to acquire environmental data and to decision making. To illustrate the maturity of WSN, we present the SMIR platform having one or more wireless sensor networks based on iLive (scalar), MiLive (multimedia) and hybrid (scalar and multimedia), one or more local servers SLRs, and one or more remote servers SDRs according to application needs (Fig 1). The main elements of iLive are: a temperature sensor, an air humidity sensor, a light sensor, 3 Decagon and 4 Watermark sensors and IEEE802.15.4 wireless medium. Powered by 2 AA standard batteries, the lifetime of iLive node is longer than 5 years (one sample per day). The main MiLive elements are: a color camera and a wireless medium IEEE802.11.g. Note that MiLive node can be combined with an iLive node to form a hybrid wireless node (multimedia and scalar). To illustrate the capabilities of the platform SMIR two application examples will be presented: intelligent irrigation system and multi-scale environment data acquisition system.

Kun Mean HOU was born in Cambodia in 1956. He held a PhD degree in 1984 and a HDR degree in 1996 in Computer Science from the University of Technology of Compiègne (UTC), France. He worked as associate professor at UTC from 1984 to 1986. In 1986 he joined IN2 as R&D engineer group leader to develop fault-tolerant super-minicomputer. From 1989 to 1996, he led a research group, which investigated parallel architecture dedicated to real-time image processing at laboratory HEUDIASYC UMR 6599 CNRS (UTC). In 1997 he joined the college of engineering school ‘ISIMA: Institut Supérieur d’Informatique de Modélisation et de leurs Applications’ as full professor, where he created the SMIR ‘Systèmes Multisensoriels Intelligents integers et Répartis’ group of the laboratory LIMOS UMR 6158 CNRS (10 researchers). SMIR group focuses on the development of core (basic hardware and software) technologies dedicated to Wireless Sensor Network, IoT and WoT. Different sensor nodes (Bluetooth, Wi-Fi and ZigBee), embedded wireless communication and embedded real-time kernel (SDREAM, LIMOS and HEROS) are implemented and deployed in different applications such as telemedicine, intelligent transportation system and precision agriculture. He holds 4 patents, and he evolved in 3 EU projects and 20 technology transfers. He is also evolving in several scientific committees and boards. He is an ICT-AGRI EU expert. |
