Testbed Working Group

• Research areas include : developing Future Internet testbed (e.g. KOREN) to perform end-to-end experiments over diverse, advanced technologies and realize interoperability, manageability, customization, accessibility, virtualization, and sliceability

• NIA is leading this and Policy WG

20

Proposal

• Federated Testbed Project using KOREN and Geant through TEIN2

• Interesting topics include, - Ubiquitous Sensor related work : Sensor Node, Gateway, Ad-hoc Router, OS, Tiny stack, Protocol, Service and Application - Sensor Map or Web related work(GIS + LBS + USN), Global Logistics : Asset and History Tracing, information sharing on Environmental issues, i.e. Co2, Water, Global Warming - Future Internet related Topics : Wireless Mesh network, Ambient, Programmable Router, Network Virtualization

• International Cooperation on FP7 or self- funding joint research projects
