Cryptography Methods for Software-Defined Wireless Sensor Networks

The Software-Defined Wireless Sensor Networking (SDWSN) paradigm aims to solve inherent issues present in Wireless Sensor Networks (WSN), such as resource constraints, by adopting a Software-Defined Networking (SDN) approach to the management of these WSNs. The security aspect of SDWSN has received little attention due to a focus on the architecture. As this paradigm is a combination of both WSN and SDN, some solutions from both paradigms can be adapted to consider SDWSN. One of the main problems with implementing security within WSN, lies within its inherent issues, such as resource constraints. However, due to the centralization of control brought about by the SDN paradigm, most of these issues are alleviated, leaving room for WSN security implementations. In order to investigate the use of WSN cryptography within SDWSN, cryptography methods have been implemented within a SDWSN network in order to verify whether the SDWSN paradigm does allow for resource intense WSN security implementations.
