1. A communication system, comprising:
- a receiver capable of receiving data at a data reception rate; and
an energy harvesting electrical power source, capable of producing an output power that is available to the receiver,where the receiver is configured in operation to maximize the average power consumption of the available output power of the energy harvesting power source while maintaining a peak power consumption below the available output power of the energy harvesting power source, andwhere the receiver is configured in operation to;
increase the data reception rate when the available output power of the energy harvesting power source is predicted to increase, unless the data reception rate is at a maximum value; and
decrease the data reception rate when the available output power is predicted to decrease.

Abstract
A method, system, and device provide power-efficient communications within the context of available power. Transmission and receipt data rates are scalable in accordance with output power available from a power source. Data is transmitted at a data rate determined, at least in part, by the available output power.

7. A communication system, comprising:
-
a transmitter capable of transmitting data at a data transmission rate; and an energy harvesting electrical power source, capable of producing an output power that is available to the transceiver, wherein the transmitter is configured in operation to maximize an average power consumption of the available output power of the energy harvesting power source while maintaining a peak power consumption below the available output power of the energy harvesting power source, and wherein the transmitter is further configured in operation to; increase the data transmission rate of the transceiver after a number of consecutive successful transmissions or when the available output power is predicted to increase, unless the data transmission rate is at a maximum value; and decrease the data transmission rate of the transceiver after one or more unsuccessful transmissions or when the available output power is predicted to decrease. - View Dependent Claims (8, 9, 10, 11)
