Abstract
Methods for jointly determining tones, power, scheduling and routing of links in a multi-carrier, multi-hop network to achieve certain desired throughput objectives between source and destination nodes. The methods effectively enhance or optimize throughput received by each destination router under node traffic constraints such as power, scheduling and flow constraints that apply to each link between each of a plurality of nodes within the mesh network.
Claims18
A method for transmitting data between a plurality of nodes in a wireless network, the plurality of nodes being interconnected via a plurality of wireless links, the method comprising:
- determining at least one link routing characteristic for transmitting data between at least two of the plurality of nodes based on at least one desired data throughput characteristic for each source/destination pair selected from the plurality of nodes and a set of link routing constraints associated with the plurality of nodes;
- and
- transmitting data between the plurality of nodes in accordance with the at least one link routing characteristic;
- wherein
- the set of link routing constraints includes a per node sum power constraint for each node among the plurality of nodes that are transmitting data, and
- each per node sum power constraint specifies a constraint on a transmit power at a node among the plurality of nodes that are transmitting data.
