Random Linear Network Coding (RLNC) has been proven to improve the performances of Internet of Things (IoT) devices, such as throughput and resilience. However, for latency-sensitive applications, sliding window RLNC (SWNC) outperforms the block-based RLNC because it allows instantaneous packet decodeability and reduces the in-order delay. However, most conventional SWNC approaches have been applied to single-hop communication networks since recoding at intermediate nodes destroy the properties of the coding windows. In this work, we consider multi-hop communication networks and propose SWNC-based recoding algorithms that can be applied at inter-mediate nodes. The simulation results show that the proposed recoding algorithms outperform block-based RLNC by 53% in terms of the per-packet delay performance.
