  • Binary Blind Identification of Wireless Transmission Technologies for Wide-Band Spectrum Monitoring
    2011 IEEE Global Telecommunications Conference - GLOBECOM 2011, 2011
    Co-Authors: Huy Nguyen, Nam Nguyen, Guanbo Zheng, Rong Zheng
    Abstract:

    Spectrum Monitoring is important to ensure the safe operation of mission critical systems as well as the satisfactory performance of non-critical applications over wireless. In this paper, we present a novel blind technology identification (BTI) approach that utilizes only binary representation of Spectrum activities to identify transmission technologies that are present in the radio Spectrum. Spectrum observations are modeled as Boolean OR mixtures on the underlying signal sources, and the binary independent component analysis technique is applied. Not only can we reveal the latent independent wireless technologies, but their transmission statistics and activities at each time slot can also be inferred. Evaluation results on both synthetic and real Spectrum traces show that without any high-level features, the proposed methodology achieves high inference accuracy in noisy measurements.

  • CITS - Wide area and wide band Spectrum Monitoring system based on sensor networks
    2016 International Conference on Computer Information and Telecommunication Systems (CITS), 2016
    Co-Authors: Weilong Hu, Zan Li, Linlin Liang
    Abstract:

    With the increasing importance of radio Spectrum in the national economy and safety, this paper develops a wide area and wide band radio Spectrum Monitoring system which uses sensor networks. The significant contribution of the paper is introducing wireless sensor networks into the design of the Spectrum Monitoring system. A Spectrum Monitoring oriented private network architecture is designed to realize the networked Spectrum Monitoring, and make the multi-node cooperation possible. So far, our system has covered the old and new campus of Xidian University, the forth telecom science institute, and other test regions, and continuously operated for two years. Under the Monitoring band with 20MHz-8GHz, the system can achieve integrated comprehensive signal processing and intelligent analysis including signal detection, modulation recognition and location-tracking. The system solves the problems of Spectrum Monitoring and signal processing, which can be applied to Spectrum Monitoring in the complex electromagnetic environment.

  • empirical validation of commodity Spectrum Monitoring
    International Conference on Embedded Networked Sensor Systems, 2016
    Co-Authors: Ana Nika, Xia Zhou, Ben Y Zhao, Zhijing Li, Haitao Zheng
    Abstract:

    We describe our efforts to empirically validate a distributed Spectrum Monitoring system built on commodity smartphones and embedded low-cost Spectrum sensors. This system enables real-time Spectrum sensing, identifies and locates active transmitters, and generates alarm events when detecting anomalous transmitters. To evaluate the feasibility of such a platform, we perform detailed experiments using a prototype hardware platform using smartphones and RTL dongles. We identify multiple sources of error in the sensing results and the end-user overhead (i.e. smartphone energy draw). We propose and implement a variety of techniques to identify and overcome errors and uncertainty in the data, and to reduce energy consumption. Our work demonstrates the basic viability of user-driven Spectrum Monitoring on commodity devices.

  • towards commoditized real time Spectrum Monitoring
    Proceedings of the 1st ACM workshop on Hot topics in wireless, 2014
    Co-Authors: Ana Nika, Zengbin Zhang, Xia Zhou, Ben Y Zhao, Haitao Zheng
    Abstract:

    We are facing an increasingly difficult challenge in Spectrum management: how to perform real-time Spectrum Monitoring with strong coverage of deployed regions. Today's Spectrum measurements are carried out by government employees driving around with specialized hardware that is usually bulky and expensive, making the task of gathering real-time, large-scale Spectrum Monitoring data extremely difficult and cost prohibitive. In this paper, we propose a solution to the Spectrum Monitoring problem by leveraging the power of the masses, i.e. millions of wireless users, using low-cost, commoditized Spectrum Monitoring hardware. We envision an ecosystem where crowdsourced smartphone users perform automated and continuous Spectrum measurements using their mobile devices, and report the results to a Monitoring agency in real-time. We perform an initial feasibility study to verify the efficacy of our mobile Monitoring platform compared to that of conventional Monitoring devices like USRP GNU radios. Results indicate that commoditized real-time Spectrum Monitoring is indeed feasible in the near future. We conclude by presenting a set of open challenges and potential directions for follow-up research.
