Abstract
A network manager device in an industrial wireless network sends a network investigating message to other network nodes for processing and forwarding through the network, the message including a message weight. A wireless communication device providing a node in the network receives the message from another network node, 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.
