Abstract

Claims (20)

1. A method of sending data from a source node in a wireless communications network, comprising:

determining, at a source node, a list associated with each of a plurality of available routing paths, each list including parameters for the associated available routing path, at least one of the parameters being selected by an end user; and

first selecting one of the plurality of available routing paths, from the source node to a destination node, on which to send data based on routing criteria specified by the source node and determined from the parameters in the list.

2. The method of claim 1 , wherein the routing criteria is given by a price function.

3. The method of claim 2 , wherein the price function includes at least one of (i) a current primary routing path status of the plurality of available routing paths, (ii) a number of hops associated with each of the plurality of available routing paths, (iii) a user-defined priority value associated with each of the plurality of available routing paths, (iv) a known delay from the source node to the destination node along each of the plurality of available routing paths and (v) a known bandwidth from the source node to the destination node along each of the plurality of available routing paths.

4. The method of claim 3 , wherein the routing criteria includes a plurality of parameters prioritized in a hierarchical order and including at least two of (i), (ii), (iii), (iv) and (v).

5. The method of claim 4 , wherein (iii) is ranked higher in the hierarchical order than (i) or (ii).

6. The method of claim 4 , wherein (ii) is ranked higher in the hierarchical order than (i).

7. The method of claim 2 , further comprising:

second selecting another of the plurality of available routing paths; and

second sending data from the source node to the destination node along the second selected routing path.

8. The method of claim 7 , wherein the second selecting step is performed periodically.

9. The method of claim 8 , wherein the second selecting step is performed in response to performance degradation on the first selected routing path.

10. The method of claim 1 , wherein the routing criteria includes a plurality of parameters prioritized in a hierarchical order.

11. The method of claim 1 , further comprising:

first sending data from the source node to the destination node along the first selected routing path.

12. The method of claim 1 , further comprising:

determining a number of the available routing paths; and performing the first selecting step if the number is greater than 1.

13. The method of claim 1 , wherein the wireless communications network is a Ad-hoc On-demand Distance Vector (AODV) network.

14. The method of claim 1 , wherein the parameters selected by the end user are evaluated based on a price function.
