Model based path selection in a Bluetooth low energy, BLE, mesh network

摘要

A method for supporting the establishment of a path for transmitting a message in a mesh network, wherein said message is to be transmitted from a source node in said mesh network to a destination node, via one or more intermediary nodes, in said mesh network. The method comprises the steps of receiving, by an intermediary node in said mesh network, a path discovery message originating from said source node in said mesh network, said path discovery message comprising a path quality parameter, updating, by said intermediary node, said path quality parameter based on a quality of link associated with a node from which said intermediary node received said path discovery message, and broadcasting, by said intermediary node, said path discovery message wherein said broadcasted path discovery message comprises said updated path quality parameter. A complementary method and corresponding node are also presented herein.
