Apparatus and method for controlling transmission of sensor data on media access control (MAC) layer of wireless sensor network

摘要

A method for controlling transmission of sensor data by a coordinator of a wireless sensor network, the method including transmitting a data frame received from a sensor device to a PAN coordinator; in response to no acknowledgement message being received from the PAN coordinator during a predetermined period of time for waiting to receive an acknowledgement message, retransmitting the data frame; and, in response to a number of retransmission attempts of the data frame being exceeding a maximum number of retransmission attempts, transmitting Data Transmission Stop Notification to the sensor device in order to stop to receive any data frame from the sensor device.

1. A method for controlling transmission of sensor data by a coordinator of a wireless sensor network, the method comprising:
transmitting a data frame received from a sensor device to a PAN coordinator; in response to no acknowledgement message being received from the PAN coordinator during a period of time to receive an acknowledgement message, retransmitting the data frame; and in response to a number of retransmission attempts of the data frame exceeding a maximum number of retransmission attempts, transmitting a Data Transmission Stop Notification to the sensor device to stop receiving any further retransmission of the data frame from the sensor device.
