IT-SDN is a Software Defined Wireless Sensor Network (SDWSN) tool that is completely open and freely available, designed to be independent of the operating system and its functions. Although it is inspired by TinySDN (a previous work on my research group), we improved the architecture, protocols and implementation.
The IT-SDN framework version presented here was developed under Contiki OS 3.0 and the controller software was developed in C and C++ with Qt.

IT-SDN version 0.4 (October/2018) - Improvements/modifications include: 1) code improvements for better understanding; (2) serial NACK to deal with controller buffer overflow; (3) improvements on routing calculation on the controller; (4) addition of packets to support monitoring and management.
IT-SDN version 0.3 (April/2018) - Improvements/modifications include: (1) enhanced criteria to trigger route recalculation on controller; (2) enhanced topology updating process; (3) tweaked some Collect parameters to decrease control overhead; (4) minor enhancements/bug corrections.
IT-SDN version 0.2 (September/2017) - Improvements/modifications include: (1) added control packet reliability; (2) route recalculation on controller triggered by overall route cost change, instead of link change; (3) minor bug corrections.
