In IoT environment, heterogeneous sensors and actuators are connected with high performance computers such as cloud servers or local servers. Commonly servers and actuators work in constrained environments with limited computation. Recently several IoT standard frameworks have been published with heterogeneous protocols. For interworking between various protocols, we present an IoT proxy for interworking IETF CoAP and OCF IoTivity. An IoT proxy can connect between IETF CoAP and OCF IoTivity in IoT networks. In this paper, we have design IoT proxy server using .NET framework and IoT devices using android platform with IoTivity framework. The interworking proxy server has been developed to support CoAP and IoTivity to transfer data between IoT system and IoT devices.
