Cumulative route metrics for wireless mesh network routing
First Claim
1. A wireless network device comprising:
- a physical layer module configured to send and receive packets wirelessly; and
a mesh routing module configured toreceive a first packet from a second wireless network device via the physical layer module, wherein the first packet includes a metric and a source address,determine a cumulative metric based on (i) the metric from the first packet and (ii) a link metric,transmit a second packet to a third wireless network device via the physical layer module, wherein the second packet includes the cumulative metric, anddetermine the link metric based on (i) a state of charge of a power supply of the wireless network device and (ii) a transmission parameter of the second packet.

Abstract
A wireless network device includes a physical layer module configured to send and receive packets wirelessly. The wireless network device includes a mesh routing module configured to receive a first packet from a second wireless network device via the physical layer module. The first packet includes a metric and a source address. The mesh routing module is further configured to determine a cumulative metric based on (i) the metric from the first packet and (ii) a link metric. The mesh routing module is further configured to transmit a second packet to a third wireless network device via the physical layer module. The second packet includes the cumulative metric. The mesh routing module is further configured to determine the link metric based on (i) a state of charge of a power supply of the wireless network device and (ii) a transmission parameter of the second packet.
