Robust multipath routing

1. A method for communicating over a wireless network, comprising:

receiving, at a first node, a packet stream comprising Transmission Control Protocol (TCP) packets;

identifying an importance of packets of the packet stream and grouping the packets of the packet stream into at least one of a first or second group of packets based on the identified importance of the packets;

generating a copy of the second group of packets;

determining a first route for transmitting the first group of packets from the first node to a second node;

determining a second route for transmitting the second group of packets from the first node to the second node; and

determining a third route for transmitting the copied second group of packets from the first node to the second node;

wherein each of the first, second, and third routes are different routes.

2. The method of claim 1 , wherein the wireless network includes a wireless ad hoc network that includes the first node and the second node.

3. The method of claim 1 , wherein the determining the first route includes performing a multipath routing algorithm using a first value for a weighting variable.

4. The method of claim 1 , wherein the determining the second route includes performing the multipath routing algorithm using a second value for the weighting variable.

5. The method of claim 1 , wherein the first group of packets are more important than the second group of packets.

6. The method of claim 5 , wherein the first group of packets include at least one of control packets or urgent pointers.

7. The method of claim 6 , wherein the second group of packets include data packets.

8. A method for communicating over a wireless network, comprising:

Receiving, at a first node, a packet stream comprising Transmission Control Protocol (TCP) packets;

grouping packets of the packet stream into at least one of a first or second group of packets based on packet type;

generating a copy of the first group of packets;

determining a first route for transmitting the first group of packets from the first node to a second node;

determining a second route for transmitting the second group of packets from the first node to the second node; and

determining a third route for transmitting the copied first group of packets from the first node to the second node;

wherein each of the first, second, and third routes are different routes.

9. The method of claim 8 , wherein the wireless network includes a wireless ad hoc network that includes the first node and the second node.

10. The method of claim 8 , wherein the determining the first route includes performing a multipath routing algorithm using a first value for a weighting variable.

11. The method of claim 8 , wherein the determining the second route includes performing the multipath routing algorithm using a second value for the weighting variable.

12. The method of claim 8 , wherein the first group of packets are more important than the second group of packets.

13. The method of claim 12 , wherein the first group of packets include at least one of control packets or urgent pointers.

14. The method of claim 13 , wherein the second group of packets include data packets.

15. The method of claim 13 , wherein the control packets includes at least one of a TCP acknowledgement (ACK) packet, a Request to Send (RTS) packet, or a Clear to Send (CTS) packet.

16. A wireless communication system comprising:

a wireless node including a processor and a wireless transceiver coupled to the processor, the processor configured to:

receive, at a first node, a packet stream comprising Transmission Control Protocol (TCP) packets;

group packets of the packet stream into at least one of a first or second group of packets based on packet type;

generate a copy of the second group of packets;

determine a first route for transmitting the first group of packets from the first node to a second node;

determine a second route for transmitting the second group of packets from the first node to the second node; and

determine a third route for transmitting the copied second group of packets from the first node to the second node;

wherein each of the first, second, and third routes are different routes.

17. The wireless communication system of claim 16 , wherein the determining the first route includes performing a multipath routing algorithm using a first value for a weighting variable.

18. The wireless communication system of claim 16 , wherein the determining the second route includes performing the multipath routing algorithm using a second value for the weighting variable.

19. The wireless communication system of claim 16 , wherein the first group of packets include at least one of control packets or urgent pointers.

20. The wireless communication system of claim 19 , wherein the second group of packets include data packets.
