| 发明名称 | Method and apparatus for collision avoidance in sensor network | ||
| 摘要 | Disclosed is a method and apparatus for collision avoidance in a sensor network. The method includes transmitting data by a transmitter; comparing, by the transmitter, a remaining time between the data transmission and a backoff period with a turnaround time taken for the transmitter to switch from a transmit (Tx) mode to a receive (Rx) mode; selectively transmitting, by the transmitter, a busy signal indicating that a channel is in use, according to the comparison result; and receiving, by the transmitter, an acknowledgement (ACK) signal from a receiver after the turnaround time has elapsed. | ||

| 主权项 | 1. A method for collision avoidance in a sensor network in compliance with a predetermined standard, the method comprising: transmitting data by a transmitter; comparing, by the transmitter, a remaining time between the data transmission and a backoff period with a turnaround time taken for the transmitter to switch from a transmit (Tx) mode to a receive (Rx) mode; selectively transmitting, by the transmitter, a busy signal indicating that a channel is in use, according to the comparison result; and receiving, by the transmitter, an acknowledgement (ACK) signal from a receiver after the turnaround time has elapsed, wherein the selectively transmitting of a busy signal comprises transmitting, by the transmitter, the busy signal if the remaining time is less than the turnaround time. | ||
