Abstract
SDN-WISE is a Software Defined Networking solution forWireless Sensor Networks (WSNs). This work shows thepeculiarities of SDN-WISE, and how easy it is programmingthe behavior of a WSN by exploiting the SDN-WISE features.
Features
SDN-WISE introduces some novel functions which areparticularly convenient in WSNs:
I StatefulnessI Flexible definition of rulesI Support of duty cyclesI Support of multitenancyI Lots of deployment options and programming languagesI Integration with simulation environments
Design and Implementation
Figure: SDN-WISE@INFOCOM testbed and protocol stack.
Downloads
The source code of the controller and the firmware areavailable under GPL 3.0 licence on GitHub. For moreinformation please visithttp://sdn-wise.dieei.unict.it.
Use Case
Figure: Two controllers operating on the same network.
Testbed
I Sensor nodes:. Embit IEEE 802.15.4 boards (EMB-Z2530PA). Memory: 8 kB RAM + 256 kB Flash memory. 40 kB of memory used for MAC (TIMAC v.1.4.0). 10 kB of memory used for SDN-WISE
I Control plane:. WISEVisor + Controllers hosted in the same PC. Controllers implemented in Java
Figure: SDN-WISE@University of Catania testbed.
Conclusions
SDN-WISE reduces the amount of information exchangedbetween sensors and the SDN controllers by using a statefulapproach and provides a new level of abstraction which allowsseveral logical WSNs to coexist over the same set of sensornodes.
