  • Abstract In the development of the Internet of Things(IoT)nowadays, there are a lot of wire and wireless communication standards because of the improvement of the communication technology. Therefore, heterogeneous network gateway plays an important role in IoT network. However, current management of the processing in data routing technique for heterogeneous network gateway is not efficient. Today, the Internet used IP-based packet as a core technique over all internet services so that the connection difficulty increases when there are more and more devices. Also, Modbus is a standard protocol using in the sensor layer in IoT for aiding data monitoring. Often apply on the device which has simple network physical interfaces. If the nodes have same node number connection to the heterogeneous network gateway which supports Modbus protocol, it will cause the node ID confliction. Furthermore, if it is used in different network architecture, the adaption decreases because the packet forwarding control plane and data plane have been in a tight couple state. To cope these problem, this thesis uses software defined networking architecture to design the DNS-like heterogeneous network smart switch. Separating control and data plane through OpenFlow can make switch become more flexible in network because the device and administrator can design and deploy under different network architecture. The Slave ID problem in Modbus heterogeneous network can be solved by using smart routing from smart switch. The node connected to smart switch has to be registered in smart switch and managed by the node name. User doesn’t have to know the node position and the IP address of the node. Data exchange just uses the Find Path by ID and Find Path by Name proposed in this thesis and unfixed string and this improves the connection experience substantially. In the final, we implement the node registration flow、client connection flow and client data access through the OpenFlow module in NS3 then show our algorithm result by using Wireshark.
