The IoT(Internet of Things), which means to connect all of the things around us to the Internet, enables us monitor and control status of things. A huge number of clients communicate with a server using various band-width in IoT environment. The Constrained application protocol(CoAP) has been proposed by IETF so as to use in IoT. However, the difference between the performance of CoAP and HTTP in various communication environment is not shown. This paper shows some indicators in a case where the CoAP works more effectively than HTTP based on a simulation.
