A fundamental challenge in underwater wireless sensor networks (UWSNs) is that acoustic links are subject to high transmission power with high channel impairments. These channel impairments result in higher error rates and temporary path losses which restrict the efficiency of these networks. Besides this, the availability of limited resources and continuous node movements are major threats for reliable...
This paper addresses the issue of energy efficiency and the optimal data packet size/length in underwater wireless network communications in the context of effective and efficient data transmission. In light of the limited battery power of underwater sensor nodes, energy efficiency is investigated in relation to the optimization of data packet length to meet the low power constraints of the shallow...
