Rédaction : Juin 2008The development of sensor network technologies is an incentive for industries to consider alternatives reducing costs and complexity while improving reliability. Among the current wireless solutions, IEEE 802.15.4/ZigBee LP-WPAN technology provides the mechanisms and the necessary guarantees for industrial use. We propose synchronization mechanisms entirely deterministic allowing the use of the IEEE 802.15.4 standard slotted mode in a meshed network, and the « AODV en » adaptive routing method for messages sent in a wide area network. Firstly, we look at the IEEE 802.15.4/ZigBee technology, especially its ability to retain its deterministic behavior and energy efficiency in a meshed network architecture. This study show...
