Abstract—Underwater communication has been gaining a lot of attention as it is one of the challenging and promising wireless communications. It may experience considerable latency and attenuation with respect to the distance which degrade the overall performance of the system. Moreover, literature has been investigating several techniques for Energy Harvesting (EH) for Underwater Communications (UWC). Thus, integrating underwater wireless sensor nodes (UNs) with EH abilities to communicate underwater is considered in our work. An Underwater Wireless Sensor Network (UWSN) is proposed, the network model uses optical harvesters in constraint of using optical transmitters in the power communications/harvesting. On the other hand, the communications between UNs are investigated to use Radio Frequency (RF) and optical links. Also, network throughput in both scenarios of RF and optical communications between the UNs is studied with respect to the depth of the nodes.
