1. A protocol for discovering bi-directional links during route establishment via a reactive routing protocol in a multi-hop wireless network, the protocol comprising:

  • each of a plurality of source and intermediate nodes transmitting a route request, at least one such node transmitting the route request on a plurality of wireless interfaces;

    upon receiving a route request, each node creating at least one reverse link to the node from which the route request was received;

    each of a plurality of destination and intermediate nodes transmitting, 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; and

    upon receiving a route reply, each node creating at least one forward link to the node from which the route reply was received.
