This paper focuses on the comprehensive event detection and localization problem which efficiently detects not only the number and the position, but also the event signal strength of events in sensor networks. We consider the practical situation where multiple events may simultaneously occur, their signal with heterogeneous strength attenuates over distance and their signal propagation region may...
There are increasing interests on mobile opportunistic networks which have promising applications. Constructing a mobile backbone can effectively improve the packet delivery performance of a mobile opportunistic network by excluding poor relay nodes and reducing packet collisions. However, it is highly challenging to construct an effective mobile backbone because of the absence of the quantitative...
