METHOD AND APPARATUS FOR PACKET RETRANSMISSION FOR LOW-POWER WIRELESS SENSOR COMMUNICATIONS

摘要

The present invention relates to a retransmission apparatus and a method for low-power wireless sensor communications in the coordination of a sensor network. The method includes: a step of receiving packets transmitted through the guaranteed time slot (GTS) of a CFP offset allocated to itself from multiple sensor devices, a step of checking the error of each of the received packets, a step of generating an integration response frame which includes response (ACK) information to be transmitted to each of the devices according to the result of the checked error, and a step of transmitting the generated integration response frame to the devices.
