“…Using δ, it estimates the scaling factors δα, δb, and δk, used to estimate RTTcurrent, RTTVARcurrent, and RTOcurrent, respectively. [14] measures RTT using a timestamp and determines the distance between CoAP, the requestor, and the responder using the Euclidean distance formula [31]. The distance between two nodes is determined using the node's coordinates (x, y) (either requestor or responder).…”

“…FASOR has three distinctive featuresan adaptation of the RTO backoff and RTO computation which can be fast or slow. DCC-CoAP [14] efficiently predicts network congestion; it combines the separation of nodes and multiple RTT measurements, reducing CoAP message loss. CoCoA++ [15] uses the delay gradients method to measure network congestion and introduces a new backoff mechanism called probabilistic backoff to deal with congestion.…”

“…In basic CoAP, RTO was not dependent on RTT value and later certain solutions came where different RTO values computed considering RTT. However, the paper [13] consider distance between the nodes along with the RTT values for computing RTO. This mechanism would enable to pick nearly optimal value based on the distance ensuring for nearby nodes RTO is small while for distance nodes initial RTO is large.…”

“…Several works have been presented in Wireless Ad hoc and Sensor Networks for CC in constrained application protocol; recently, CC mechanisms for CoAP are in other studies, [27][28][29][30][31][32][33] and notable contributions on CC for reliable exchanges of CoAP communications include other studies. [20][21][22]24,[34][35][36] The Internet Engineering Task Force (IETF) RFC 7641 18 provides an extension of the CoAP base specification for CC in unreliable CoAP communications as CoAP with Observe, which uses a publish-subscribe mechanism, with the introduction of an upper limit for the permitted rate of outgoing messages.…”
