Conjoined class-based networking
A data communication network includes two logically distinct class-based networks conjoined by at least one common node that has membership in each of the respective classes of the two logically distinct class-based networks. Optionally, three or more class-based networks may be conjoined to form a data communications network.

communicating the message to a destination node in the wireless network if the message is intended for receipt by the destination node, the communicating of the message by the first node including:
determining whether one or more network pathways from the first node to the destination node are known by the first node;
determining a preferred network pathway from the known network pathways based at least in part on the link quality associated with each of the one or more known network pathways; and
communicating the message to the destination node via the preferred network pathway in the wireless network.

7. The method of claim 1 , wherein said determining the preferred network pathway from the known network pathways further includes comparing a number of hops between the nodes in the known network pathways.
8. The method of claim 1 , further comprising recording, for each message received by the first node from the other node via the communication link, data generally indicative of a time at which each of the messages was communicated via the network pathway.
9. A wireless communication device operating as a node for communication in a wireless network comprising a plurality of nodes, the wireless communication device comprising:

for each message received by the receiver from the other node via the communication link with the other node, record a network pathway by which the message was communicated in the wireless network and a link quality between the other node and the node;
communicate the message, using the transmitter, to a destination node in the wireless network if the message is intended for receipt by the destination node, the communication of the message including to:
determine whether one or more network pathways from the node to the destination node are known by the node;
determine a preferred network pathway from the known network pathways, based at least in part on the link quality associated with each of the one or more known network pathways; and
transmit the message, using the transmitter, to the destination node via the preferred network pathway.
10. The wireless communication device of claim 9 , wherein if there is no known network pathway from the node to the destination node, the electronic components are configured to:
communicate with the plurality of nodes within communication range of the node to determine a network pathway to the destination node.
11. The wireless communication device of claim 9 , wherein the determination of the preferred network pathway from the known network pathways, based at least in part on the link quality, comprises a determination of the preferred network pathway based on an overall link quality of each of the one or more network pathways.
12. The wireless communication device of claim 11 , wherein the determination of the preferred network pathway from the known network pathways comprises a comparison of the overall link quality of the known network pathways.
13. The wireless communication device of claim 9 , wherein the determination of whether the one or more network pathways from the node to the destination node are known by the node, includes a search of the maintained information for a network pathway from the node to the destination node.
14. The wireless communication device of claim 13 , wherein the maintained information that is searched includes any network pathway to the destination node that is identified with the message.
15. The wireless communication device of claim 9 , wherein the determination of a preferred network pathway from the known network pathways further includes a comparison of a number of hops between nodes in the known network pathways.
16. The wireless communication device of claim 9 , wherein the electronic components are configured to record, for each message received by the node from the other node via the communication link, data generally indicative of a time at which each of the messages was communicated via the network pathway.
17. A wireless communication system comprising:
a plurality of nodes configured for communication in the wireless communication system;
a node of the plurality of nodes configured to maintain information regarding communication links between the plurality of nodes in the wireless communication system, the node configured to:
for each communication link that is established with another node, record an identification of the other node;
for each message received from the other node via the communication link with the other node, record a network pathway by which the message has been communicated in the wireless network and a link quality between the other node and the node; and
communicate the message to a destination node in the wireless network if the message is intended for receipt by the destination node, the communication of the message initiating the node to:
determine whether one or more network pathways from the node to the destination node are known by the node;
