Wireless Sensor Networks (WSN) play an important part in enabling the Internet of Things, but WSN application development and resource management are still a costly endeavour. This cost is related to the diversity of resource constrained platforms and network protocols, which demand specialized knowledge and practice. To solve this, we propose WARM: a framework that employs Web Service and Software Defined Networking paradigms to enable the parametrized scheduling of tasks. WARM allowed us to configure typical applications running on a simulated WSN using a web browser. Furthermore, we consider that WARM enables the concept of Sensing as a Service.
