In logistics, lost or spoiled goods result in inefficiency and increased costs, and so do delays. Counteracting these effects relies on being able to collect all essential information in real time. Another key factor in making efficient use of production resources is to ensure an optimized supply of spare parts. Equipment and vehicles have to be continuously maintained and available. Thanks to active smart objects based on wireless sensor nodes, we are closing the gap in logistics between the physical world and the world of information.
