- The Internet of Things (IoT) is the result of many different enablingtechnologies such as embedded systems, wireless sensor networks, cloudcomputing, big-data, etc. used to gather, process, infer, and transmit data.Integrating all these technologies requires a comprehensive and holisticresearch effort to address all the challenges imposed by these technologies,especially for sensing and delivering information from physical world tocloud-hosted services. In this paper, we outline the most important issuesrelated to standardization efforts, mobility of objects, networking and gatewayaccess, and QoS support. In particular, we describe a novel IoT networkarchitecture that integrates Software Defined Networking (SDN) and the ObjectManagement Group's Data Distribution Service (DDS) middleware. The proposedarchitecture will improve service delivery of IoT system and will bringflexibility to the network.
