Abstract:
1. A computer-implemented method for reducing transmission overhead in a first network, the method comprising: configuring a first node to join the first network; receiving a plurality of routing advertisements associated with the first network; transmitting the plurality of routing advertisements to a first plurality of nodes that belong to a second network and are neighbors of the first node; receiving an indication of interest from one or more nodes included in the first plurality of nodes in response to the plurality of routing advertisements that were transmitted, wherein the indication of interest indicates a first route included in the plurality of routing advertisements; accumulating a count of the received indications of interest; determining whether the count exceeds a predetermined threshold; and inserting the plurality of routing advertisements in a beacon packet for broadcast transmission when the count exceeds the predetermined threshold; or inserting the plurality of routing advertisements in a unicast packet for unicast transmission to a node in the one or more nodes when the count does not exceed the predetermined threshold.
