Transmission power control for wireless communication devices

A method of controlling transmission power by a transmission power controller of a network device, the method comprising:

• transmitting, via a transceiver, at an initial transmission power, an initial data transmission intended for at least one receiving device on a network;
• receiving, via the transceiver, an initial response from the at least one receiving device, the initial response including an initial received signal strength indication, RSSI;
• determining a power loss based on the value of the initial transmission power and the received RSSI;
• determining a new transmission power based on the determined power loss;
• transmitting, at the new transmission power, one or more additional data transmissions intended for the at least one receiving device;
• determining an expected transmission count, ETX, for one or more additional data transmissions;
• determining an average ETX based on the determined ETXs;
• and
• monitoring the average ETX to determine whether link quality is deteriorating.

At least one non-transitory computer-readable medium having computer program logic stored thereon, the computer program logic including instructions that, when executed by a processor, cause the processor to:

• transmit, via a transceiver communicably coupled with the processor, and at an initial transmission power, an initial data transmission intended for at least one receiving device on a network;
• receive, via the transceiver, an initial response from the at least one receiving device, the initial response including an initial received signal strength indication, RSSI;
• determine a power loss based on the value of the initial transmission power and the received RSSI;
• determine a new transmission power based on the determined power loss;
• transmit, at the new transmission power, one or more additional data transmissions intended for the at least one receiving device;
• determine an expected transmission count, ETX, for one or more additional data transmissions;
• determine an average ETX based on the determined ETXs;
• and
• monitor the average ETX to determine whether link quality is deteriorating.
