Innovative approach to Wireless Sensor Networks: SD-WSN

Traditional Networks are dominated by hardware constraints and have inflexible architectural design, thus restricting research and innovation. SDN is an innovation in networking which provides administrators to centrally manage and conFigure entire network. SDN simplifies and improves network management. Intelligent SDN controllers conFigure network elements and cooperate with applications to enhance the network. Primary objective of SD-WSN is that existing WSN can profit by making use of SDN. WSN's deployment can be developed to improve transmission performance. In this survey, the basics of SDN, WSN, SD-WSN are explained. Also developments in WSN through SDN and its challenges have been discussed. Besides, the paper also summarizes the architecture of SDN and WSN. Future research and related challenges have been discussed towards the end.
