Abstract

Things in the IoT(Internet of Things) make various services by exchanging information over networks. The IoT includes many types of WSNs(Wireless Sensor Networks) that consists of spatially distributed wireless sensor nodes and operates with the various purposes with useful technologies such as identification, sensing and communication. Typically, Zigbee network composed of low-cost and lowpowerdevices is mainly used for wide-area monitoring and remote device control systems. The IoT composed of various WSNs cannotinteroperate among networks because of heterogeneous communication protocol and different data representation of each network, but canfacilitate interconnection and information exchange among networks via the DDS, which is communication middleware standard that aimsto enable real-time, high performance and interoperable data exchanges. In this paper, we proposed design of Zigbee Adaptor for two-way interoperation and data exchange between Zigbee network and other networks in the IoT. Zigbee Adaptor communicates with Zigbeenetwork according to the Zigbee protocol and communicates with external networks via DDS. DDS-based Zigbee Adaptor can facilita teinteroperation between a Zigbee network and external networks by systematic cooperation among its components.
