Secure Remote Monitoring of Personal Health Appliances (SEMOHealth)

SDN+SDR/WARP Testbed at Oulu

World’s first Cognitive Radio Call in 2010

Oulu/Budapest 3.5G Validation Testbed

Testing Ultra-flat Network architecture with different security options

Optimal Backoff Protocol for WiFi Networks

WiFi testbed (12 stations)Our empirical evidence, simulation results and an analytic model reveal that two new protocols achieve nearly perfect fairness and throughput up to 100% higher than in standard backoff

Decrease collision rate by more than half and to reduce delays in delay sensitive traffic.

Vuokatti World’s 1st Undeground Ski Tunnel

1,210m

Great for testing NLOS wireless communication

Usecase: Secure networking of locomotives at opposite sides of a train with VPLS

Tunnel:• Ski-tunnel in Vuokatti (Finland);• Length: 2,0 km;• Max relief 18 m;• Pipe shape;• Similar to:

• Mine tunnel;• Subway.

• RX positions: • 150, 200, 250 and 300 m.

Each Point:• Stand with metallic

plate;• Embedded PC with

Wi-Fi;• Antennas• Laptop:• Controller;• Iperf (Server or

Client)
