A distance coefficient-based algorithm for k-center selection in wireless sensor networks

This paper proposes a distance coefficient-based scheme to solve the problem of selecting k control centers from the sensors in a wireless sensor network as well as dividing the sensors into k groups for the minimization of the distance between each control center and its farthest sensor. The proposed scheme can avoid the drawback of applying the farthest-first or the nearest-first method in the control centers selection.
