Battery efficient routing in mesh networks

A first wireless device for wireless communication in a wireless mesh network, comprising:

• a processor;
• memory in electronic communication with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the first wireless device to:
• receive messages from wireless devices within the wireless mesh network, each of the messages comprising a value indicating a quantity of wireless devices that relayed the message while operating using a respective battery source;
• determine, based at least in part on the messages, that a second wireless device transmitted a first message with a value that corresponds to the lowest quantity of wireless devices that relayed that message while operating using the respective battery source;
• and
• transmit a second message over a path that includes the second wireless device based at leak in part on the determination.

A non-transitory computer readable medium storing code comprising instructions executable by a processor to cause a first wireless device in a wireless mesh network to:

• receive messages from wireless devices within the wireless mesh network, each of the messages comprising a value indicating a quantity of wireless devices that relayed the message while operating using a respective battery source;
• determine, based at least in part on the messages, that a second wireless device transmitted a first message with a value that corresponds to the lowest quantity of wireless devices that relayed that message while operating using the respective battery source;
• and
• transmit a second message over a path that includes the second wireless device based at least in part on the determination.
