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).
Claims24
A method for improving a current wireless communication route between a source node and a destination node in an on-demand wireless communication network, the method comprising:
- analyzing at a local node a data packet transmission from the source node, the data packet transmission including a current route metric of a current active route between the source node and the destination node, wherein the local node is within radio range of both the source node and the destination node, and further wherein the local node is not operating within the current active route;
- determining at the local node that the local node can provide an improved wireless communication route as compared to the current active 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 through the local node and requests the source node to transmit a route request (RREQ) packet.
A system for improving a current wireless communication route in an on-demand wireless communication network, the system comprising a local node comprising:
- a wireless networking communication interface, operating to receive a data packet transmission from a source node and destined for a destination node, the data packet transmission including a current route metric of a current active route between the source node and the destination node, wherein the local node is within radio range of both the source node and the destination node, and further wherein the local node is not operating within the current active route;
- a processor operatively connected to the communication interface for analyzing the current route metric including determining whether the local node can provide an improved wireless communication route as compared to the current active route;
- and
- a memory operatively connected to the processor;
- the wireless networking communication interface further operating to transmit a route improvement message when the local node can provide an improved wireless communication route as compared to a current active route, between the source node and the destination node, having a better route metric than the current route metric of the current active route, wherein the route improvement message informs the source node that the improved wireless communication route is available through the local node and requests the source node to transmit a route request (RREQ) packet.
