Nevertheless, LS is originated from wireless environments and hence may exhibit potential vulnerabilities that can be exploited by adversary in the vicinity. As to this, it is widely believed in existing literature on LS that, a half-wavelength guard zone is sufficient to decorrelate the adversary channel from the legitimate one and thereby secures the legitimate LS. However, such an assumption may not hold universally - in some environments, high channel correlations have been observed for much larger spatial separations. Considering this, a comprehensive understanding of channel correlation in different wireless environments is needed for more confident deployment of LS-based security mechanisms. To this end, various well-established channel correlation models are investigated in this work. A set of important physical factors that have significant influence on LS security are identified, and with the obtained insights, extensive simulations are conducted to explore suitable guard zone sizes for LS in several typical indoor and outdoor environments. Experimental results based on universal software radio peripheral (USRP) platforms and GNURadio are also presented to further support the analysis.}, number={3}, journal={IEEE TRANSACTIONS ON WIRELESS COMMUNICATIONS}, author={He, Xiaofan and Dai, Huaiyu and Shen, Wenbo and Ning, Peng and Dutta, Rudra}, year={2016}, month={Mar}, pages={2104–2117} }
 @inproceedings{shen_liu_he_dai_ning_2015, title={No time to demodulate - fast physical layer verification of friendly jamming}, DOI={10.1109/milcom.2015.7357518}, abstractNote={Jamming attacks are well-known threats to wireless communications, but on the other hand they provide insights for researchers to design novel approaches to protect wireless communications. In recent years, friendly jamming is used by a number of research works to achieve the wireless medium access control. However, in these works, the friendly jammer relies on bit-level information to distinguish the allies' wireless transmissions from the enemies', which requires the received signals to be processed through demodulation steps and thus introduces a non-trivial reaction time delay for the friendly jammer. This reaction delay is undesirable as the transmissions need to be jammed while they are still on the air. To address this problem, we propose fast friendly jamming, which eliminates the need for demodulation and enables the friendly jammer to verify the received signals directly on the physical layer. We have implemented a prototype of the proposed techniques based on GNURadio and USRP, and performed real-world experiments to validate the proposed techniques. The experiment results show that the proposed techniques reduce the normal reaction delay of the friendly jammer by 81.9%-85.7%, and achieve the accurate distinction between allies' and enemies' transmissions.}, booktitle={2015 ieee military communications conference (milcom 2015)}, author={Shen, W.

For tourism enterprises, market areas are geographically dispersed with many customers residing beyond the immediate area surrounding the attraction. Visualization and analysis of these distributed market areas are significantly enhanced by the capabilities of Geographic Information System (GIS) technology and help to support management objectives. Unfortunately, many businesses are unable to utilize GIS due to its complexity and expense. This study develops a decision support tool for tourism planning and marketing that is customized and easy to use, employs open source software to reduce expense, and allows for broad accessibility via web delivery. Users can easily visualize and examine the spatial distribution of their own United States (US) client origins and visitation patterns along with relevant tourism-specific and general demographic information. This functionality can be beneficial in developing or augmenting business plans or marketing strategies, and for informing tourism theory.}, number={7}, journal={Journal of Travel & Tourism Marketing}, publisher={Informa UK Limited}, author={Supak, Stacy Kathleen and Devine, Hugh Alexander and Brothers, Gene Leroy and Rozier Rich, Samantha and Shen, Wenbo}, year={2014}, month={Oct}, pages={835–853} }

The basic idea is to jam the wireless channel continuously but properly control the jamming signals with secret keys, so that the jamming signals are unpredictable interference to unauthorized devices, but are recoverable by authorized ones equipped with the secret keys. To achieve the ally friendly jamming capability, we develop new techniques to generate ally jamming signals, to identify and synchronize with multiple ally jammers. This paper also reports the analysis, implementation, and experimental evaluation of ally friendly jamming on a software defined radio platform. Both the analytical and experimental results indicate that the proposed techniques can effectively disable enemy wireless communication and at the same time maintain wireless communication between authorized devices.}, journal={2013 IEEE SYMPOSIUM ON SECURITY AND PRIVACY (SP)}, author={Shen, Wenbo and Ning, Peng and He, Xiaofan and Dai, Huaiyu}, year={2013}, pages={174–188} }
