ABSTRACT

Selecting a suitable routing metric is crucial in attaining high-throughput in any wireless network architecture. A wrong choice may lead to selecting lossy links. In this chapter, we investigate the performance of various non-probing-based routing metrics over underwater acoustic networks (UANs). Non-probing-based routing metrics are chosen since most of the nodes in UANs operate on battery power and these routing metrics use less energy. Although, there are a couple of different routing metrics proposed for UANs, a few investigations have been performed to understand the behavior of various routing metrics over underwater network architecture. In this chapter, we take an initiative to investigate and analyze the performance of various non-probing-based routing metrics by designing a simple underwater simulator using an underwater channel model. The ndings of the investigation could be applied in selecting a suitable routing metric as well as in designing a new high-throughput routing metric for UANs.
