A Method, Devices and a Wireless Mesh Network for Establishing a Route between a Route Originator, RO, Mesh Node and a Route Destination, RD, Mesh Node in a Mesh Network

摘要

Method of establishing a route between a Route Originator, RO, mesh node and a Route Destination, RD, mesh node in a mesh network, said mesh network comprising a plurality of mesh nodes, said method comprising the steps of assembling a Route Request, RREQ, message, broadcasting said assembled RREQ message in said mesh network, receiving, by said RD mesh node, via any of said plurality of mesh nodes, said RREQ message, and transmitting, by said RD mesh node, a Route Reply, RREP, message towards said RO mesh node, and receiving, by said RO mesh node, via any of said plurality of mesh nodes, said RREP message thereby establishing said route between said RO mesh node and said RD mesh node, wherein an Route Sequence Number is used, which is a number specific for a pair of RO mesh node and RD mesh node.
