MinSum Movement of Barrier and Target Coverage using Sink-based Mobile Sensors on the Plane

Emerging IoT applications have brought up new coverage problems with sink-based mobile sensors. In this paper, we first focus on the MinSum Sink-based Line Barrier Coverage (SLBC) problem of covering a line barrier with mobile sensors originated at sink stations distributed on the plane. The objective is to minimize the movement sum of the sensors for the sake of energy efficiency. When the sinks emit sensors with non-uniform radii, we prove the...
