Energy-efficient operation is mandatory in wireless sensor networks due to the limited energy budget of sensor nodes. Considering the potential application of wireless sensor networks in logistics, cost efficiency is another major requirement due to high cost pressure. To save on data transmissions within such sensor deployments, which account for the major part of energy consumption and monetary costs, the authors develop a method for data filtering based on an in-network determination of transmission relevance of sensor data. Their approach explicitly incorporates interdependencies between wireless sensor nodes and their measurements and data transmissions.
