Wireless sensor networks provide a promising means to enable real-time monitoring of transport processes in logistics. In a corresponding logistics wireless sensor network, energy-efficient operation is mandatory. Cost efficiency and customer satisfaction are additional requirements to be explicitly considered, particularly in the application domain of logistics. As data transmission constitutes the most expensive operation in terms of energy consumption and monetary costs, the authors propose in this paper a concept for local data filtering to reduce the number of data transmissions. Their concept utilizes multiple thresholds and explicitly incorporates customers' information demands to decide whether a data transmission shall take place or not.
