Abstract: With the huge developments of underwater communication technologies, the UWSNs have played a significant role to realise profitable sea and water resource discovery/management applications. The existing UWSN works do not investigate data delivery cost-aware multi-mode data transmission by considering different communication links, forwarding nodes, networking devices, and resource allocation. Another crucial challenge is the selection of cluster-head and forwarding nodes. A majority of existing works investigate only underwater sensors' cluster head selection rather than both cluster head and forwarding nodes. This paper comes up with a data delivery cost-aware scheme with a best-fit resource allocation for UWSNs. This paper provides an integrated network model by coordinating terrestrial, non-terrestrial, and underwater networks. This paper yields a numerical model that includes finish time, energy depletion cost, network survivability, throughput, and utility metrics. The results of the proposed scheme achieve at least 45% utility gain than the traditional schemes.

Keywords: underwater sensor networks; UWSNs; best-fit resource allocation; energy utility; cluster head and forwarding node selection; throughput; network survivability.
