Other studies have sought to improve reliability by refining ACK and token mechanisms. Foe example, Selective ACK strategies were proposed in [13], Duplicate-suppression filters for lowĄ© power networks were introduced in [14] etc. Although these methods enhance message correlation and filtering, they rely on fixed retransmission timers and therefore lack dynamic adjustment to varying ACK-delay conditions. Results of these is that redundant retransmissions still occur under variable latency or partial packet loss.
