Abstract

The Industrial Internet-of-Things (IIoT) networks consist a large number of wireless sensor nodes. As the wireless spectrum available for IIoT networks is limited, there will be access contention among the nodes. The access contention causes collision, forcing them to retransmit the same packet multiple times and to continuously sense the channel to determine the suitable time for retransmission. As a consequence, each device will have high energy consumption and transmission latency. We propose a contention resolution (CR) algorithm that replaces continuous sensing with one slot sensing time and reduces the number of retransmission time to improve transmission latency and energy consumption of the nodes. Simulation results indicate that our proposed algorithm improves the energy efficiency, throughput and latency by 1600 times, 35% and 47%, respectively as compared to other schemes in the literature.
