Energy-efficient wireless communications via feedback

摘要

Methods and apparatus, including computer program products, are provided for energy efficient communication based on feedback. A method may include sending a first message carried by a first wireless radio channel at a first predetermined energy level; receiving, in response to the first message, a second message carried by a second wireless radio channel; comparing the first message to the second message; sending a termination message, when the comparing indicates the first message and the second message match; and sending a portion of the first message at a second predetermined energy level, when the comparing indicates the second message contains at least one error when compared to the first message.

主权项

1. A method comprising:
sending, by a radio, a first message to another radio, the first message carried by a forward wireless radio channel and sent at a first forward energy level; receiving, at the radio and in response to the first message, a second message carried by a feedback wireless radio channel from the other radio, the second message sent at a feedback energy level; comparing contents of the first message and the second message to determine whether at least one error is present; sending a termination message to the other radio, when the comparing indicates the first message and the second message have contents that match; and when the comparing indicates the at least one error is present,
determining, at the radio, a second forward energy level, the second forward energy level optimized based on a total energy constraint for a system including the radio and the other radio, the total energy constraint representing a sum of the first forward energy level, the second forward energy level, and the feedback energy level, andresending, by the radio, the first message to the other radio, the first message retransmitted at the determined second forward energy level optimized based on the total energy constraint for the system.
