This paper investigates a class of mobile wireless sensor networks that are unconnected most of the times; we refer to them as delay–tolerant wireless sensor networks (DTWSN). T...
Various notions of coverage provided by wireless sensor networks have attracted considerable attention over the past few years. In general, coverage can be expressed geometrically...
The applications of Wireless Sensor Networks are seriously constrained by energy supply. So how to prolong the network lifetime is an important and challenging issue, which is the ...
