The authors in [18] studied how to form barrier coverage by leveraging multiple types of heterogeneous mobile sensors, and proposed a greedy movement algorithm to efficiently schedule different types of mobile sensors to different gaps while minimizing the total moving cost. In [19], the authors ...
