Greedy geographic routing in large-scale sensor networks: a minimum network decomposition approach
In geographic (or geometric) routing, messages are expected to route in a greedy manner: the current node always forwards a message to its neighbor node that is closest to the des...

On Minimizing the Maximum Sensor Movement for Barrier Coverage of a Line Segment
We consider n mobile sensors located on a line containing a barrier represented by a finite line segment. Sensors form a wireless sensor network and are able to move within the lin...
