Delay-bounded adaptive UFH-based anti-jamming wireless communication [PDF]

2011 Proceedings IEEE INFOCOM, 2011
Anti-jamming communication without pre-shared secrets has gained increasing research interest recently and is commonly tackled by utilizing the technique of uncoordinated frequency hopping (UFH). Existing researches, however, are almost all based on ad hoc designs of frequency hopping strategies, lacking of theoretical foundations for scheme design and

How can children and young people have a voice in urban treescapes?

People and Nature, EarlyView.
Abstract Scientific understanding of climate change has, to date, failed to result in sufficient action. This paper proposes that a deficit model of top‐down learning and dissemination in relation to public engagement with science may be part of the problem, particularly when considering the attitudes, values and empowerment of children and young ...
