Abstract
A method and apparatus for routing the same data through independent routes between stations in a mesh network to increase the robustness of communications. The disclosed feature allows transmission of the same data stream via multiple routes from a source station (STA) to a destination station (STA). An extended routing request (RREQ) and routing reply (RREP) are utilized which provide a primary and secondary flag indication, which is utilized in combination with advanced programming for setting path cost metrics to assure independence of primary and secondary routes.
