This paper proposes a novel routing protocol enriched with an assigning mechanism that enables for efficient data flow coordination, among communication nodes with heterogeneous spectrum availability in distributed cognitive radio networks. Efficient routing protocol operation, as a matter of maximum-possible routing paths establishments and minimum delays is obtained, by utilizing a signaling ...

BACKGROUND Health communication inequalities were observed in Western population but less is known about them among the Chinese. We investigated health information seeking behaviours and its social determinants among Chinese adults in Hong Kong. METHODS Probability-based sample surveys over telephone were conducted in 2009, 2010/11 and 2012 to monitor family health and information use. Freque...

Television since its invention has been considered a social link between people. People chat and discuss television programs, recommend shows to be watched, and send SMS messages when there is something of interest on. Like previous technologies, the digitalization of the medium imposed a number of technological priorities such as transmission mechanisms or middleware standardization. Once the ...
