摘要： The present disclosure relates to method of allocating time slots for sensor node sample transmission from sensor nodes in a wireless sensor node network which forms part of a control system for controlling an industrial process. The method comprises receiving (S1-1) a sample from a first sensor node in a first time slot of a superframe, which first sample has a value outside an accepted range of values, obtaining (S 2 ) an identification of a second time slot of the superframe in which second time slot the first sensor node is to send a further sample in a subsequent superframe, and providing instructions (S 5 ) to the first sensor node to send the further sample in the second time slot of a subsequent superframe. A computer program product and a sensor node network interface system are also disclosed herein.

摘要： A wireless communication device providing a node (30) in an industrial wireless network (WN) investigates if there is more than one data packet with process control data from the same data originating device destined for a process control device (16) in a transmission queue, where the data originating device is an interface to the process being controlled and transmits data packets in the transmission queue. If there is more than one such data packet, the wireless communication device further compares time stamps of the data packets, where a time stamp reflects the time of generation of a corresponding data packet, keeps the newest data packet and discards older data packets, so that only the most recent data packets from a data originating device are sent to the process control device from the node.

摘要： A network manager device (20) in an industrial wireless network (WN) sends a network investigating message to other network nodes (24, 26, 28, 30, 32, 34) for processing and forwarding through the network, the message comprising a message weight. A wireless communication device providing a node (30) in the network receives the message from another network node (24), determines a communication weight based on the quality of communication, adds the communication weight to the message weight and compares the sum with the node weight. If the sum is lower than the node weight, it is set as new node weight and as new message weight, whereupon the changed message is sent to other nodes in the network. The network manager device maps the topology of the network based on updated node weights, sets a communication scheduling scheme based on the mapped topology and informs the network nodes of the scheme.
