Abstract
A method for communication between a wireless device node in a wireless sensor network (WSN) and control apparatus or control processes of an industrial control system is used to determine a method of radio transmission which provides a greater or a lesser measure of transmission quality between nodes. Thus a transmitter node measures a transmission quality metric of at least one packet received from two or more different switching branches, identifies which of the two or more switching branches has the greater transmission quality metric, distributes data packets with a first priority to the switching branch with the greater transmission quality metric, and transmits data packets with the first priority such as real-time data on the switching branch with the greater transmission quality metric. A wireless node, a sensor network system and a computer program for carrying out the method are described.
