Abstract:
1. A method of establishing a multipath route in a heterogeneous interface environment among a plurality of wireless nodes comprising a source node, one or more relay nodes, and a destination node comprising a plurality of heterogeneous interfaces, the method comprising: receiving a route request message comprising a destination node address from the source node via at least one relay node of the one or more relay nodes at the destination node; and establishing a relationship between at least two heterogeneous interfaces of the plurality of heterogeneous interfaces of the destination node in response to determining whether the destination node address exists in an address table of the destination node, wherein the establishing of the relationship between the at least two heterogeneous interfaces comprises: wherein the transmitting of the route reply message comprises transmitting the route reply message in response to the determining that the destination node address matches the address of the second heterogeneous interface, and wherein the destination node is a final node to which data is transmitted from the source node along the routing path indicated by the route reply message.
