In this paper, an IoT system which is increasingly popular in these days is developed. Among various international standards on the area, one M2M communication protocol is used in the system. The 0neM2M-based IoT system consists of ADN-AE modules and CSE modules. The ADN-AE module provides applications of various services. It also monitors a CSE module. The CES module is a platform that Received (January 9, 2016), Review Result (January 22, 2016) Accepted (January 29, 2016), Published (March 31, 2016) (Corresponding Author) Computer Eng.

Development of an IoT System Based on the oneM2M Communication Protocol Copyright c 2016 HSST 42 provides common services which should be provided to various AEs in an IoT system. The CSE module consists of a Network Manager module, a Message Handler module, and a Resource Manager module. The Network Manager module controls oneM2M communication and data flow in the system. The Message Handler module processes transmitted messages and the Resource Manager module manages the Resource Tree. The resource tree stores information of the objects to be managed in the system. Also, internal data flow and protocol mapping in the modules are explained. |
