Managing QoS for Future Internet Applications over Virtual Sensor Networks

The integration of Wireless Sensor Networks (WSNs) in the Future Internet has opened new opportunities for novel applications that meet the needs of modern societies. Virtualisation of the available resources and the services offered by WSNs enables their efficient sharing between diverse applications reducing costs. Responding to this challenge, the VITRO project has designed a WSN virtualization architecture that targets to decouple the physical sensor infrastructure from the applications running on top of it. In the concept of Virtual Sensor Network platform, the WSNs are capable of collaborating among each other (even if they belong to different administrator domains or comprise of heterogeneous platforms) to flexibly support service composition and fuel novel application development. To meet the diverse Quality of Service (QoS) requirements imposed by the different applications running on top of the same infrastructure, VITRO has designed, implemented and integrated a routing solution that enables the establishment of different routing paths per application, based on different routing criteria in order to optimize the performance aspect(s) of interest to each application. In this paper, we demonstrate how the VITRO routing solution could be employed in various use cases including smart homes/buildings, smart cities, smart business environments and securityrelated applications. We evaluate the achieved performance using computer simulation results and provide guidelines for prospective users.
