Abstract

 The CoAP (Constrained Application Protocol) protocol and its improvements are still limited in its ability to detect congestion early and adjust transmission rates to match the dynamic state of the Internet of Things networks. This paper proposes a solution to implement a fuzzy control mechanism for network congestion avoidance with the selection of appropriate input and output parameters. The parameters are evaluated by the simulation tool. The simulation results show that the parameter selection is suitable for the theory, allowing the fuzzy control system to achieve higher performance indices compared to the standard CoAP.
