Smart City Renovation using SDN Framework

Research and development in different technical dimensions of smart city has been a key challenge. It requires successful renovation with suitable technology and innovative design models while sharing knowledge and amenity to the society. Satellite communication plays an important role in providing accurate and timely information to the user nodes present in the community. Software-defined networking (SDN) has been evolved as an emerging platform in the last decade and solves various challenges faced by traditional network used in satellite communication. In this paper, we present an SDN deployed design framework for traffic management and weather forecasting in smart city environment. Our design framework is integrated into the ground stations and consists of four modules, namely; data retrieval, computation, verification, and information circulation. These modules coordinate with each other along with the satellites, and user nodes. The accuracy of the proposed framework is verified using a Z3 constraint solver. Also, the performance is compared with TCP/IP network and existing GPS systems. The results show 98% accurate message detection, 38% enhancement in throughput, and approximately 25ms delay in delivering the messages to the user devices.
