In recent years, a typical representation of the next-generation Internet architecture, named data networking (NDN), and a critical form of the underwater Internet of Things (IoT), underwater acoustic sensor networks (UASNs), have attracted widespread attention in academia. Meanwhile, since the battery energy of the sensor node is limited and the battery is difficult to replace or recharge in underwater environments, extending the networks' lifetime has become a key issue in UASNs. In this paper, we try to deploy a UASN on NDN architecture and explore the energy consumption of the NDN-based UASN under shallow water and deep water conditions based on the relay network topology. A simulation is carried out to compare the delay performance of NDN-based and IP-based UASNs and validate the result. It is believed that the study could provide a theoretical criterion for the selection of the direct or relay path to optimize energy consumption in the future deployment of NDN-based UASNs.INDEX TERMS Energy consumption, named data networking, underwater acoustic sensor networks.

This paper develops a realistic battery model that is combined with transmitting signal energy and circuit power consumption, and applies it to wireless sensor networks (WSNs). Then, we calculate the critical values of distances of the source-destination node pairs without considering the relay path. Meanwhile, we intuitively present the relay area and the difference of energy consumption between the single-hop direct path and the multi-hop relay path. Several results give the criterion for the selection of singlehop direct path or the multi-hop relay path to save energy.
