METHOD AND APPARATUS FOR POWER EFFICIENT DOWNSTREAM COMMUNICATION IN SENSOR NETWORKS |
| 摘要 |
Methods and apparatuses are described for asynchronous communications in a sensor network. An indication of a receiving opportunity can be transmitted by a sensor device. The sensor device can then provide the receiving opportunity based at least in part on transmitting the indication, and disable communication resources at the sensor device for a duration of a sleep time following the receiving opportunity. An upstream node can generate information for communicating to a sensor device, receive the indication of the receiving opportunity from the sensor device, and transmit the information to the sensor device during the receiving opportunity based at least in part on receiving the indication. |

1. A method for communicating in a sensor network, comprising:
transmitting, by a sensor device, an indication of a receiving opportunity at the sensor device; providing the receiving opportunity at the sensor device based at least in part on transmitting the indication; and disabling communication resources at the sensor device for a duration of a sleep time following the receiving opportunity. |
