14、2018) 1263–1269 12652.2 IoT Vision Various definitions of IoT co-exist due to the fact that everyone gives it a meaning according to their own perspective leading to obvious fuzziness. The definition is a mix of two te

15、rms-Internet and Things. The former gives it a network-oriented vision whereas the latter one pushes it towards objects which are combined to get settled in a single architecture. IoT signifies “world-wide network of i

16、nterconnected objects uniquely addressable based on standard communication protocols” [11]. The biggest challenge in IoT is to uniquely identify each object in parallel with representation and storage of the informatio

17、n that is exchanged among the objects. The three visions of IoT [8] are shown in fig 2: 1. Things Oriented Vision 2. Internet Oriented Vision 3. Semantic Oriented Vision Fig 2: Vision of IoT [8] A. Things Oriented Vi

18、sion In this vision, objects are tracked by sensors and technologies using RFID [27]. Each object is uniquely identified by Electronic Product Code (EPC). The data is collected through sensors and sensor based embedded

19、 system. This vision depends on RFID-based sensor networks and other sensor-based networks which integrate technologies based on RFID, sensing, computing devices and the global connectivity. B. Internet Oriented Visio

20、n The internet-oriented vision sees the various physical devices interacting with each other. The sensor-based objects can be determined uniquely and their whereabouts can be regularly monitored. These smart embedded o

21、bjects can be considered as microcomputers with computing resources. C. Semantic Oriented Vision This vision states that the data collected through sensors will be huge. Thus, the collected data is processed effectiv

22、ely. The raw data is processed in order to make it consistent and least redundant which is useful for better representations and interpretation. From things perspective, IoT focuses on the integration of smart devices

23、or objects in a single architecture, where things being RFID tags, the Internet perspective gives IoT a network-oriented meaning. As IP being the worldwide accepted protocol to connect the various communicating objects
