Disseminating data from sources to sinks is a very important application in sensor networks. This paper presents a new data dissemination scheme which uses the concept of the Fermat Point to construct a dissemination tree from one source (the root) to multiple sinks (the leaves). By sending data along the dissemination tree, the new scheme can conserve transmission energy, avoid collision and a...

Data dissemination problem is a challenging issue in social networks, especially in mobile social networks, which grows rapidly in recent years worldwide with a significant increasing number of hand-on mobile devices such as smart phones and pads. Short-range radio communications equipped in mobile devices enable mobile users to access their interested contents not only from access points of In...

In order to reveal how sucrose degradation is related to chilling tolerance, two varieties of peach fruit, ‘Zajiao’ and ‘Yulu’, were treated with 1-methylcyclopropene (1-MCP) vapor at 1 μL/L for 24h before storage at 5 oC for 35 and 28 d respectively. ‘Yulu’ peaches had higher sucrose content than ‘Zajiao’ peaches at harvest, but a higher rate of sucrose degradation in untreated ‘Yulu’ fruit ma...
