Abstract

A system and method for improving a current wireless communication route, between a source node and a destination node in an on-demand wireless communication network, enables the current communication route to be improved even when the current route has not failed. The method includes analyzing at a local node a packet transmission from the source node, the packet transmission comprising a current route metric (step 705). The local node then determines that it can provide an improved wireless communication route, between the source node and the destination node, having a better route metric than the current route metric (step 710). A route improvement message is then transmitted from the local node to the source node (step 740).

Claims

AMENDED CLAIMS received by the International Bureau on 09 may 2008We claim:
1. A method for improving a current wireless communication route between a source node and a destination node in an on-demand wireless communication network3 the method Comprising: analyzing at a local node a packet transmission from the source node, the packet transmission comprising a current route metric; determining at the local node that the local node can provide an improved wireless communication route, between the source node and the destination node, having a better route metric than the current route metric; and transmitting a route improvement message from the local node to the source node, wherein the route improvement message informs the source node that the improved wireless communication route is available.
2. The method of claim 1, wherein the route improvement message comprises a request for the source node to transmit a route request (RKEQ) packet.
3. The method of claim 1, wherein determining at the local node that the local node can provide an improved wireless communication route comprises determining that an improved route metric is better than the current route metric by a predetermined threshold.
4. The method of claim 1, wherein determining at the local node that the local node can provide an improved wireless communication route comprises comparing respective Packet Completion Rates (PCRs) of the improved wireless communication route and the current wireless communication route. 19
5. The method of claim I , wherein determining at the local node that the local node can provide an improved wireless communication route comprises comparing respective Expected Transmission Times (ETTs) of the improved wireless communication route and the current wireless communication route.
6. The method of claim 1 , wherein determining at the local node that the local node can provide an improved wireless communication route comprises comparing parameters of the improved wireless communication route and the current wireless communication route3 wherein the parameters are selected from a group comprising throughput, delay, jitter, signal strength, and packet completion rate.
7. The method of claim 1, wherein determining at the local node that the local node can provide an improved wireless communication route comprises analyzing PCR or ETT data received from an intermediate node in the current wireless communication route.
8. The method of claim 1, further comprising delaying transmitting the route improvement message for a predetermined time interval.
9. The method of claim 8, wherein transmitting the route improvement message occurs only when a stability of the improved wireless communication route does not fall below a predetermined threshold during the predetermined time interval.
10. The method of claim 1, further comprising delaying transmitting the route improvement message for ft random time interval.
20
11. The method of claim 10, wherein transmitting the route improvement message occurs only when an alternative route improvement message is not received during the random time interval.
12. The method of claim 1 , wherein analyzing at a local node a packet transmission from the source node occurs only during a route optimization period.
13. The method of claim 1 wherein the local node and the destination node are the same node.
14. The method of claim 2, further comprising: transmitting the route request packet (RREQ) by the source node; and re-determining by the source node an optimized wireless communication route to the destination node based at least in part on one or more received responses to the route request packet (RREQ).
