ABSTRACT

In this chapter, we study the optimal clustering in Underwater Acoustic Sensor Networks (UW-ASNs). Although clustering has been well studied for the terrestrial wireless sensor networks (WSN), the unique characteristics of underwater acoustic communications call for a new study. Because the path loss is not only relevant to the distance, but also related to the working frequency, the optimal cluster size for
