Power efficient communications
First Claim
Patent Images
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 a portion of the available output power of the energy harvesting power source useable to receive data 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 transmitter, wherein the transmitter is configured in operation to maximize a portion of the available output power of the energy harvesting power source usable to transmit data 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 transmitter 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 transmitter after one or more unsuccessful transmissions or when the available output power is predicted to decrease. - View Dependent Claims (8, 9, 10, 11)

12. A method of communication, comprising:
-
determining an available output power of an energy harvesting power source that is currently available for operation; maximizing a portion of the available output power used to receive data while maintaining a peak power consumption below the available output power of the energy harvesting power source; receiving data at a data reception rate; increasing 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 decreasing the data reception rate when the available output power is predicted to decrease. - View Dependent Claims (13, 14, 15, 16, 17)
