Abstract
A method and system using inter-node interference data to improve the routing of data within a wireless mesh network.
Claims21
A method adapted for use in a node of a wireless mesh network comprising a plurality of nodes, the method comprising:
- determining, for each of a plurality of links supporting any of a plurality of data transmission paths, a long term link quality (LTLQ) parameter;
- determining, for each of said plurality of links, an interference aware routing metric (iAWARE) parameter associated with any respective proximate links;
- adapting the LTLQ parameter of each of said plurality of links according to the respective iAWARE parameter to determine thereby a link quality parameter;
- and
- routing data according to said link quality parameter.
2 more elements
A system, comprising:
- an input/output circuit adapted to receive data streams;
- a memory, for storing computer instructions for a method of processing the received data stream;
- and
- a processor, for executing the computer instructions;
- wherein while executing the computer instructions the processor operates to perform a method comprising:
- determining, for each of a plurality of links supporting any of a plurality of data transmission paths, a long term link quality (LTLQ) parameter;
- determining, for each of said plurality of links, an interference aware routing metric (iAWARE) parameter associated with any respective proximate links;
- adapting the LTLQ parameter of each of said plurality of links according to the respective iAWARE parameter to determine thereby a link quality parameter;
- and
- routing data according to said link quality parameter.

A computer program product stored on non-transitory readable medium wherein computer instructions, when processed by a computer, adapt the operation of the computer to perform a method of routing data in a wireless mesh network, the method comprising:
- determining, for each of a plurality of links supporting any of a plurality of data transmission paths, a long term link quality (LTLQ) parameter;
- determining, for each of said plurality of links, an interference aware routing metric (iAWARE) parameter associated with any respective proximate links;
- adapting the LTLQ parameter of each of said plurality of links according to the respective iAWARE parameter to determine thereby a link quality parameter;
- and
- routing data according to said link quality parameter.
