Existing studies to examine CoAP retransmission mechanisms from various perspectives include Fixed exponenˇ©tial backoff [4), probabilistic retransmission [5], cross-layer congestion control [6], and Machine-learning-based adaptive schemes [7], as cited in our paper. However, most of these approaches either lack fine-grained adaptability to dynamically varying network delays or fail to directly address the duplicate-response problem in separate-response communication. Moreover, most these focus primarily on throughput or fairness, rather than achieving a balanced trade-off between reliability and latency under delay-sensitive loT conditions
