Abstract: This paper proposes a Time-Constrained Target Points Patrolling (TCTP) Algorithm which aims at constructing an efficient patrolling route for a number of given data mules such that the visiting intervals of all target points can be minimized. For the scenario containing weighted target points, a Weighted-TCTP (W-TCTP) Algorithm is further proposed to satisfy the demand that targets with higher weights have higher data update frequencies. Performance study demonstrates that the proposed algorithms outperform existing approaches in terms of visiting intervals of the given targets and length of patrolling path.
