While it has been a belief for over a decade that Wireless Sensor Networks (WSN) are application-specific, the authors argue that it can lead to resource underutilization and counter-productivity. They also identify two other main problems with WSN: rigidity to policy changes and difficulty to manage. In this paper, they take a radical, yet backward and peer compatible, approach to tackle these problems inherent to WSN. They propose Software-Defined WSN architecture and address key technical challenges for its core component, Sensor OpenFlow. This paper represents the first effort that synergizes software-defined networking and WSN.
