Underwater sensor networks can be applied to oceanographic data collection, offshore oil exploration or disaster warning. The energy resource of such networks is severely limited with no easy way to replenish the supply. One way to conserve energy is to manage the topology of the network such that redundant nodes can go to sleep. Considering an event driven application with delay-sensitive information,...
The growing interests in underwater wireless sensor networks for a wide variety of purposes from Tsunami monitoring to commercial oilfield exploration projects have been encouraging. The use of underwater wireless nodes implies nodes are battery-powered and energy conservation in such networks becomes a leading issue. Unlike land systems that can make generous assumptions about accurate time-synchronization...
