Journal ArticleDOI
IEEE 802.15.4g Based Wi-SUN Communication Systems
TL;DR: This paper summarizes Wi-SUN communication systems and their physical (PHY) layer and media access control (MAC) specifications, and fundamental transmission performances of the systems in the PHY layer and MAC layer are evaluated by computer simulations.
Journal ArticleDOI
Enabling coexistence of multiple cognitive networks in TV white space
Gabriel Porto Villardi,Yohannes D. Alemseged,Chen Sun,Chin-Sean Sum,Tran Ha Nguyen,Tuncer Baykas,Hiroshi Harada +6 more
TL;DR: This work presents a standard independent framework to enable exchange of information relevant for coexistence based on two mechanisms: centralized and distributed, and gives a concise overview of the current activities in international standardization bodies toward the realization of communications in TVWS.

TL;DR: The Project Authorization Request for the IEEE P1900.4 Working Group (WG), under the IEEE Standards Coordinating Committee 41 (SCC41) was approved in December 2006, leading to this WG being officially launched in February 2007.
Journal ArticleDOI
IEEE 1900.6: spectrum sensing interfaces and data structures for dynamic spectrum access and other advanced radio communication systems standard: technical aspects and future outlook
Maurizio Murroni,R. V. Prasad,Paulo Marques,Bernd Bochow,Dominique Noguet,Chen Sun,Klaus Moessner,Hiroshi Harada +7 more
TL;DR: The current structure of the IEEE 1900.6 standard and its relationship with other related standardization activities are outlined, application scenarios and topology are provided briefly, and open research issues that raise future challenges to the standardization community are discussed.
Proceedings ArticleDOI
Adaptive Two Thresholds Based Energy Detection For Cooperative Spectrum Sensing
Chunyi Song,Yohannes D. Alemseged,Ha Nguyen Tran,Gabriel Porto Villardi,Chen Sun,Stanislav Filin,Hiroshi Harada +6 more
TL;DR: An adaptive two thresholds based energy detection and a two stage HIC based cooperative decision for cooperative spectrum sensing to improve the sensing reliability in the circumstance with heavy noise uncertainty is proposed.
