Abstract: The Internet of things(IoT) is a networking paradigm where interconnected smart objects continuously generate data and transmit it over the Internet.However,the solutions to manage and utilize the massive volume of data produced by these objects are yet to mature.Traditional database management solutions fall short in satisfying the sophisticated application needs of an IoT network that has a truly global-scale.Current solutions for IoT data management address partial aspects of the IoT environment with special focus on sensor networks.We surveyed the data management solutions proposed for IoT or subsystems of the IoT.And finally proposed a data management framework for IoT that acts as a seed to a comprehensive IoT data management solution.The proposed framework adapts a federated,data- and sources-centric approach to link the diverse things with their abundance of data to the potential applications and services that are envisioned for IoT.

Key words: Internet of things,Data management,Federation,Sensor networks
