An NDNoT based efficient object searching scheme for smart home using RFIDs

Internet of Things (IoT) is driven by innumerable sensing devices, RFID tags and other miniature computing entities, which continuously sense, generate and compute data. One can see that our future environment will contain lots of devices that will generate the massive amount of automated data. The presence of resource constrained devices, frequent exchange of data and heterogeneous types of network traffic distinguish IoT from the current Internet. Recently, Named Data Networking (NDN) is proposed as a content retrieval solution which directly deals with application generated variable-length, location-independent names to search and pull contents for a requesting user, irrespective of hosting entity. The use of content names for communication support name-based routing, in-network caching, and security which make the NDN more suitable for IoT. In this paper, we propose a NDN-based searching mechanism (named, Search-NDNoT), which can be used to find any smart item augmented with the RFID in real-world in real-time. An energy-efficient data aggregation algorithm is also proposed to maintain up-to-date data on the server. Our proof-of-concept prototype shows the usability of our proposed system.
