IP CREWCognitive Radio Experimentation World Ingrid Moerman, Stefan Bouckaert The research leading to these results has received funding from the European Union's Seventh Framework Programme (FP7/2007-2013) under grant agreement n°258301 (CREW project).

IP CREW Cognitive Radio Experimentation World FP7 call 5 Project started October 2010 7 partners 1

Wireless developer’s questions 2 How to evaluate cognitive radio / cognitive networking solutions? … in a configurable environment … in a repeatable way … allowing fair comparison of results Should/can I build my own heterogeneous testing environment?

IP CREW: Target 3 To establish an open federated test platform, facilitating experimentally-driven research on: advanced spectrum sensing cognitive radio cognitive networking spectrum sharing in licensed and unlicensed bands

CREW platform start of project: 4 operational wireless testbeds heterogeneous ISM heterogeneous licensed cellular wireless sensor augmented with State-of-the-Art cognitive sensing platforms 4

Sensing in ISM bands 5 sensing solution A versus sensing solution B

Sensing in licensed bands 6 sensing solution A versus database approach sensing solution B

vs distributed sensing (many & cheap) Cognitive networking in ISM 7 MONITORING:{CN protocol + nodes} under test MONITORING:testbed + environment status sensing solution ACTIVE USE: use advanced sensing fornetwork optimization: distributed sensing (few & expensive)

Controlled experimentation environment 8 MONITORING repeatability inject RF interferenceand/or background traffic wirelessbenchmarking experimentation environment CR hardware available to experimenter

Federation 9 1. Same SW/HW components in different wireless environments 2. Comparison – same solution in different wireless environments vs. 3. Record & Replay (open data sets) deployment X @ experimentation environment A deployment X @ experimentation environment B

Summary Availability of Test facilities (different environments, different technologies) Advanced cognitive components Controlled experimentation environment Benchmarking ➞ reproducibility + comparability Possible usage scenarios advanced sensing for spectrum sharing horizontal resource sharing by heterogeneous networks in the ISM band cooperation in heterogeneous networks in the licensed bands, e.g. TV white spaces robust cognitive sensor networks impact of cognitive radio in primary cellular systems, in particular LTE and LTE+ More info D2.1 – Definition of Internal Usage Scenario (available Feb. 2011) 10

CREW open call We welcome new partners first open call in second half of 2011 looking for innovative experiments using the federation, as well as proposals to integrate additional cognitive radio technologies into the federation More info on CREW: http://www.crew-project.eu/ More on open calls: subscribe to the CREW newsletter ➜
