In this work, we present two routing protocols for circular underwater wireless sensor networks (UWSNs); circular sparsity-aware energy efficient clustering (CSEEC) and circular depth-based sparsity-aware energy efficient clustering (CDSEEC) with sink mobility. In CSEEC, we divide circular network area into 5 concentric circular regions. We deploye...

In this paper, to monitor the fields with square and circular geometries, three energy-efficient routing protocols are proposed for underwater wireless sensor networks (UWSNs). First one is, sparsity-aware energy efficient clustering (SEEC), second one is, circular SEEC (CSEEC), and the third one is, circular depth based SEEC (CDSEEC) routing proto...
Conference Paper
In this paper, we present a virtual chain based routing (VCBR) protocol for underwater wireless sensor networks (UWSNs). Due to sparse deployment of sensor nodes and dynamic network topology in UWSNs, void hole problem occurs. In VCBR, we build a virtual chains between sensor nodes and sink nodes to avoid void hole problem. VCBR also minimizes coll...
