This article aims to optimize the Zigbee communication protocol in wireless sensor networks used for meteorological monitoring at the National Institute of Meteorology in Lubumbashi. It addresses key limitations of the standard Zigbee protocol, particularly latency, energy consumption, and inefficient routing. By introducing an Energy-Aware AODV routing algorithm and implementing MAC-layer modifications, the study enhances transmission efficiency and network lifespan. Simulations conducted using Contiki-NG and the Cooja simulator demonstrate significant improvements in packet delivery ratio, energy efficiency, and transmission delay, validating the proposed protocol’s suitability for real-world meteorological applications.
Author Keywords: Zigbee, AODV, Protocol, energy, routing.

Abstract: (french)
Cet article vise à optimiser le protocole de communication Zigbee dans les réseaux de capteurs sans fil utilisés pour la surveillance météorologique à l’Institut National de Météorologie de Lubumbashi. Il traite des principales limitations du protocole Zigbee standard, notamment la latence, la consommation d’énergie et l’inefficacité du routage. En introduisant un algorithme de routage EA-AODV (Energy-Aware AODV) et en appliquant des modifications à la couche MAC, l’étude améliore l’efficacité des transmissions ainsi que la durée de vie du réseau. Les simulations réalisées avec le système Contiki-NG et le simulateur Cooja montrent des améliorations significatives en termes de taux de livraison des paquets, d’efficacité énergétique et de délai de transmission, validant la pertinence du protocole proposé pour des applications météorologiques en conditions réelles.
Author Keywords: Zigbee, AODV, Protocole, energie, routage.
