Abstract: An extension to reactive ad-hoc routing protocols in multi-hop wireless mesh networks. The protocol discovers bi-directional links during route establishment, particularly multiple links between a single pair of nodes. Source and intermediate nodes transmit a route request, at least one of the nodes transmitting the route request on more than one wireless interface. Upon receiving a route request, each node creates at least one reverse link to the node from which the route request was received. The destination and intermediate nodes transmit, via at least one of the reverse links, at least one route reply which enables a node receiving the route reply to identify one or more wireless interfaces of the node transmitting the route reply. Upon receiving a route reply, each node creates at least one forward link to the node from which the route reply was received. Routes may then be established using any discovered bidirectional link.
