TL;DR: This work presents a novel platform supporting different aspects of WSN virtualisation to cope with requirements dictated by diverse IoT application domains and introduces beyond state of the art technological advancements following the recent standardisation efforts in this research area.
Abstract: Decoupling hardware, software and service provisioning through principles of virtualisation has enabled the exponential uptake of today's internet. The currently emerging internet of things IoT, be it through its more academic embodiment of wireless sensor networks WSNs or more industrial embodiment of machine-to-machine networks, is, however, still fragmented due to dispersed business models, isolated administrative control, heterogeneity of devices and platforms, proprietary communications protocols, different economic interest of stakeholders and a lack of well-crafted solutions for data, information and knowledge exchange. This work presents a novel platform supporting different aspects of WSN virtualisation to cope with requirements dictated by diverse IoT application domains. It introduces beyond state of the art technological advancements following the recent standardisation efforts in this research area. The implementation of the platform and its validation through a representative real-life application scenario exploring different virtualisation facets are also reported.

TL;DR: The benefits of elastic optical networking are systematically investigated and the superiority of variable bandwidth elastic OFDM based networks with respect to the rigid grid counterparts under dynamic performance is established.
Abstract: Dynamic elastic optical networks with variable bandwidth capability are investigated with respect to the effect of the flexi-grid granularity, the capacity of the connection request in optical network and network design parameters. We systematically investigate the benefits of elastic optical networking and establish the superiority of variable bandwidth elastic OFDM based networks with respect to the rigid grid counterparts under dynamic performance.
