In our scheme the client will employ an adaptive retransmission timeout (RTO) using an exponentially weighted moving average (EWMA) of round-trip times¡¦.while at the same time the server applies a two-threshold duplicate suppression mechanism that differentiates between transient delays and actual losses.
Together, these components dynamically balance reliability and responsiveness.
Simulation and analytical results showed reductions of up to 45% in redundant messages, 25% in latency, and 18% in energy consumption compared with baseline CoAP
