Analysis of the Threshold for Energy Consumption in Displacement of Random Sensors
Consider mobile sensors placed randomly in dimensional unit cube for
fixed The sensors have identical sensing range, say We are
interested in moving the sensors from their initial random positions to new
locations so that every point in the unit cube is within the range of at least
one sensor, while at the same time each pair of sensors is placed at
interference distance greater or equal to Suppose the displacement of the
th sensor is a distance . As a \textit{energy consumption} for the
displacement of a set of sensors we consider the total displacement
defined as the sum for some constant
The main contribution of this paper can be summarized as follows. For the
case of unit interval we \textit{explain a threshold} around the sensing radius
equal to and the interference distance equal to
for the expected minimum total displacement. For the sensors placed in the
unit square we \textit{explain a threshold} around the square sensing radius
equal to and the interference distance equal to
for the expected minimum total displacement
