Abstract

Wireless Sensor Networks (WSNs) is a technology that allows to obtain data from the environment or a phenomenon in real time, as the sensor nodes have communication capabilities. Examples of WSNs applications include: environmental monitoring, eHealth, and most recently smart cities and the Internet of Things (IoT).Traditionally a WSN is deployed to support a single application. However, servicing multiple applications simultaneously becomes an important prerequisite for flexibility in deployed infrastructure. The use of the Software-Defined Networking (SDN) paradigm in WSN enables this infrastructure sharing. However, despite the long discussion in the literature, the actual use of multiple concurrent applications in a WSN infrastructure with SDN has not yet been demonstrated. Another aspect not addressed are applications involving mobile nodes. Thus, this research project of Scientific Initiation has as main objective the implementation and performance analysis of two simultaneous applications in the same WSN infrastructure based on the SDN paradigm. With this, it is expected to identify if the SDN paradigm, specifically the IT-SDN framework, allows the flexibility described in the literature. We will also analyze what happens in terms of node mobility in the WSN.
