Abstract

The Internet Engineering Task Force (IETF) designed the Constrained Application Protocol (CoAP) for Internet of Things (IoT) gadgets. The IoT devices with restricted radio channel limits and equipment assets are called constrained devices. Network communications in constrained devices face congestion because of their limited resources. To face the congestion CoAP uses a basic (CC) congestion control mechanism for solid transmission. Alternative CoAP CC mechanisms CoCoA and CoCoA+ are introduced by the IETF Constrained RESTful Environments (CoRE) Working Group. However, there had been limited evaluations have done on CoAP CC mechanisms. In this paper, we focus on this crucial study and perform evaluations that show how the default and alternative CC mechanisms contrast with one another. We utilize the Cooja simulation condition, which is one of the Contiki advancement toolset for simulating CoAP CC mechanisms in different network topologies and varying in different link delivery ratios in global event traffic scenario. By evaluating the generated results CoCoA+ shows better performance compare to Default CoAP and CoCoA.
