REACTIVE AND PROACTIVE ROUTING PROTOCOL INTEROPERATION IN LOW POWER AND LOSSY NETWORKS

摘要

In one embodiment, a border node between a reactive routing network and a proactive routing network may receive an inter-domain route request (RREQ) from a requestor for a destination, and determines whether it knows the destination. In response to knowing the destination, the border node responds to the requestor. However, in response to not knowing the destination at the border node, when the border node is ingressing the inter-domain RREQ into the proactive routing network, it sends the inter-domain RREQ to each other border node of the proactive routing network. Alternatively, when the border node is ingressing the inter-domain RREQ into the reactive routing network, it sends the inter-domain RREQ into the reactive routing network.
