IDENTIFICATION OF ROBUST WIRLESS ROUTING PATHS

摘要

There is provided mechanisms for routing packets between a terminal device and a control system node via intermediate nodes on wireless paths in a wireless network. A method comprises obtaining (S104) information on disturbances of wireless paths used for communicating packets of a traffic flow between the intermediate nodes in the wireless network. The method comprises determining (S106), based on the information on disturbances, mutual correlation between the disturbances of the wireless paths. The method comprises routing (S108) the packets of the traffic flow between the terminal device and the control system node via some of the intermediate nodes and along disjoint wireless paths, whereby the packets are transmitted in parallel on the disjoint wireless paths, and wherein the disjoint wireless paths have mutual correlation not higher than a threshold correlation value.
