Abstract
The present invention relates to a method for efficiently transmitting error-tolerant traffic in low power and lossy networks (LLNs). The method for transmitting an error-tolerant traffic includes when a packet is received, modifying a medium access control (MAC) layer of a receiving device to perform received signal strength indication (RSSI) sampling at a symbol rate and estimating a symbol error rate of the packet in the MAC layer based on the sampled RSSI value, and when the estimated symbol error rate is lower than a specific value, transmitting the received packet to a higher layer.
