A number of nodes will be densely deployed due to the further development of Internet-of-Things (IoT).If multiple nodes simultaneously send packets on the same frequency channel, packet collision happens at the gateway.This leads to packet loss.By sending an ACK signal to the node whose packet was correctly received by the gateway, the other nodes can initiate packet retransmission in order to resolve the packet loss.However, this is based on the assumption of ACK signal transmission from the gateway to all the nodes.Thus, the processing load of the gateway increases and duty cycle (DC) restriction on the gateway may be impacted.In this paper, we propose an autonomous distributed frequency resource allocation method for LoRaWAN, aiming to reduce the number of packet collisions and reduce the gateway processing load.We will show the effectiveness of the proposed approach through computer simulation and experimental evaluations by implementing the proposed approach. |
