Abstract

Internet of Things (IoT) has led to the development of smart projects by connecting heterogeneous devices and has accelerated the global growth by providing digital services to the users. The Smart City Project is very complex concept and has many hurdles in its way and many of the hurdles (Digitization services) can easily be solved by IoT. Urban IoT, is designed to support the future vision of smart cities which supported the new hybrid technologies and provide the value added services to the citizens. In this Urban IoT framework the first layer is Data Layer. In Data layer, sensor platform uses the optimized AODV-SPEED protocol (Hybrid Approach), proposed in this paper. Hybrid approach has shown improvement over delay, energy, miss ratio of the packet transmission and packet delivery rate over traditional SPEED protocol which is suitable for IoT applications. This article also identifies the framework, challenges and trends of Smart city IoT and use case for the smart street highlights the importance of proposed structure. Furthermore, Smart City projects are discussed to recognize the importance of IoT in smart cities and its future.

VIII. CONCLUSION

This article gives a look into the role and need of IoT in development of smart city. In this paper, a novel approach has also been proposed for sensor platform of the data layer of ISS-IoT. In this approach AODV with SPEED shows the value of remaining energy from .8 to 1.1 (joules) while AODV with hybrid approach shows the remaining energy, from .6 to 1.6 (joules). In packet delivery rate, the proposed methodology shows the values from 1.4 to 1.5, while the value in SPEED ranges from 0.9 to 01. Delay in proposed method ranges from 2 to 10 milliseconds which is again optimized over the SPEED, which shows delay from 2 to 11 milliseconds. Packet miss ratio of hybrid approach is 0 to 95 which is again better than SPEED which is 5 to 100. These results prove that proposed method is more suitable for the sensor platform in ISS-IoT. The framework (ISS-IoT) is also proposed for the smart street, that can also be used for other application services . To provide the sustainable growth of digital services and dynamic realization of new updates of cities, IoT plays a major role. Many projects are already in development and it is expected that in 2020, there will be a rise of 9.7 billion in connecting services. A new architecture with cognitive communication and security paradigm has been proposed to optimize the existing infrastructures. A case study on a smart street justify the validation of the new prototype.
