Evaluation Methodologies For Cooperative Spectrum Sensing: Towards A Real Time Performance

Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)The constant search for new spectrum sensing methodologies creates a demand for tools that enable a stronger focus on solution prototyping development. Such tools, generally based on a Software Defined Radio (SDR) platform, need to be flexible in terms of programming as well as presenting compatibility with the various SDR available on the market. In this contribution we present a comparison between real time and non-real time simulation methodologies for implementing some cooperative spectrum sensing algorithms. Tools and their results are compared aiming at demonstrating pros and cons of the evaluation methodologies. There is a clear tradeoff among development cost, simulation flexibility and execution time, specially considering the choice of prototyping methodology and the target application. © 2013 IEEE.Microwave Theory and Techniques Society (IEEE MTT-S),Sociedade Brasileira de Micro-Ondas e Optoeletrenica (SBMO),CNPq,CAPES,FAPERJConselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Akyildiz, I.F., Lo, B.F., Balakrishnan, R., Cooperative spectrum sensing in cognitive radio networks: A survey (2011) Phys.Commun., 4 (1), pp. 40-62. , MarArslan, H., (2007) Cognitive Radio, Software Defined Radio, and Adaptative Wireless Systems, , SpringerZeng, Y., Liang, Y.C., Maximum-minimum eingenvalue detection for cognitive radio (2007) International Symposium on Personal, , Indoor and Mobile Radio CommunicationsZeng, Y., Koh, C.L., Liang, Y.C., Maximum eigenvalue detection: Theory and application (2008) International Conference on CommunicationsNadler, B., Penna, F., Garello, R., Performance of eigenvalue-based signal detectors with known and unknown noise level (2011) IEEE International Conference on Communications, pp. 1-5Lim, T.J., Zhang, R., Liang, Y.C., Zeng, Y., GLRT-based spectrum sensing for cognitive radio (2008) IEEE GLOBECOMGuimaraes, D.A., Silva, C.R.N., Souza, R.A.A., Cooperative spectrum sensing using eigenvalue fusion for OFDMA and other wideband signals (2013) Journal of Sensor and Actuator Networks, 2, pp. 1-24Lin, F., Hu, Z., Qiu, R., Wicks, M.C., A combination of quickest detection with oracle approximating shrinkage estimation (2012) Militwy Communications ConferenceHou, S., Qiu, R.C., Spectrum sensing for cognitive radio using kernel-based learning (2011) Proceedings of CoRRKortun, A., Ratnarajah, T., Sellathurai, M., Zhong, C., Papadias, C.B.A., On the performance of eigenvalue-based cooperative spectrum sensing for cognitive radio (2010) IEEE Journal of Selected Topics in Signal Processing, 5, pp. 49-55Chen, D., Li, J., Ma, J., Spectrum sensing for cognitive radio under noise uncertainty (2008) International Conference on Wireless Communications, Networking and Mobile ComputingZayen, B., Hayar, A., Cooperative spectrum sensing technique based on sub space analysis for cognitive radio networks (2009) Cognitive Systems with Interactive Sensors ConferenceBuccardo, A., (2010) A Signal Detector for Cognitive Radio System, , Master's thesis, University of Gavlehttp://gnuradio.org/redmine/projects/gnuradio/wiki, GNU radio websiteAlvarez, P.I.P.A., (2011) Experimental Study on Spectrum Sensing for Cognitive Radio Networks, , Master's thesis, Universidade Tecnica de LisboaZhang, P., Qiu, R., Guo, N., Demonstration of spectrum sensing with blindly learned feature (2011) IEEE Communications Letters, 15, pp. 548-550Teshome, A.T., (2010) FPGA Based Eigenvalue Detection Algorithm for Cognitive Radio, , Master's thesis, University of GavleZayen, B., Hayar, A., Dimension estimation-based spectrum sensing for cognitive radio (2012) Journal on Wireless Communications and NetworkingWei, L., Tirkkonen, O., Analysis of scaled largest eigenvalue based detection for spectrum sensing (2011) IEEE International Conference on Communicationshttp://www.mathworks.comhttp://www.python.org, Python programming language-official websiteJoshi, R., (2006) Introduction to Computers, , G.P.House, Ed.Isha Bookshttp://www.nsnam.org, Network simulator 3http://jist.ece.comell.eduhttp://www.opnet.com, Optimized network engineering tool (OPNET)http://www.scipy.orgBudihal, R., Jamadagni, H.S., Hybrid approach to cognitive radio test bed (2009) International Conference on Ultra Modern Telecommunications & WorkshopsHaykin, S., (2009) Communication Systems, , WileyMitola, J., Software radios Survey, critical evaluation and future directions (1993) Aerospace and Electronic Systems Magazine, 8, pp. 25-36http://www.ettus.coml, Universal software radio peripheral (USRP)Tan, K., Zhang, J., Fang, J., Liu, Y., Ye, H., Wang, S., Zhang, Y., Voelker, G., SORA: High performance software radio using general purpose multi-core processors (2011) Communications of the Association for Computing Machinery, 54, pp. 99-107http://warp.rice.edu/, W.O.-A.R.Platform.Wireless open-access research platformDabcevic, K., (2011) Evaluation of Software Defined Radio Platform with Respect to Implementation of 802.15.4 ZigBee, , Master's thesis, Malardalen UniversityGiordano, L.G., Reggiani, L., (2013) Vehicular Technologies-Deployment and Applicationshttp://www.gppcom.ct.ufrn.br, Grupo de pesquisa em prototipagem rapida de solU(;6es para comunicaao-GppComhttp://www.py2exe.orgStevenson, C.R., Cordeiro, C., Sofer, E., Chouinard, G., (2005) Functional Requirements for the 802.22 WRAM Standard, , IEEE, Tech.Re
