Implementation and performance evaluation of efficient algorithms for slicing in real SDN-based 6LoWPAN networks

During the last years, the implementation of computational and communication capabilities in all kind of objects has given traction to the diffusion of the Internet of Things paradigm. Being sensor nodes the main building block of an IoT infrastructure, Wireless Sensor Networks are expected to play an important role in allowing the interconnection between smart devices. Hence, to overcome the rapidly increasing needs of this kind of networks, multiple solutions have been proposed in order to allow efficient management and scaling. One of these solutions is represented by the implementation of the Software Defined Networking paradigm on top of WSN infrastructures. In order to efficiently implement SDN over WSN, multiple issues must be considered, with particular attention to the fact that SDN is specifically designed for wired networks, hence it does not take into account the problematics that will arise in case of wireless communication, being the wireless medium by definition asynchronous and not perfectly reliable
