1. A router comprising:
- a processor configured to i) on a first periodic basis, initiate a transmission of a first routing update message for retransmission by a first node located within a first distance from the router;
ii) on a second periodic basis, initiate a transmission of a second routing update message for retransmission by at least a second node located within a greater distance from the router, wherein the second periodic basis is less frequent than the first period basis; and
iii) select a set of relay nodes to reduce the number of messages transmitted on a network on which the router resides.
