Much attention has been focused lately on the Opportunistic Routing technique (OR) that can overcome restrictions of harsh underwater environment and unique structures Underwater Sensor Networks (UWSNs). OR enhances performance UWSNs in both packet delivery ratio energy saving. In our work; we propose a new routing protocol; called Energy Efficient Depth-based with Void Avoidance for (EEDOR-VA)...

In underwater wireless sensor networks (UWSNs), the nodes are sparsely deployed over a large sea area due to their high design cost and manufacturing cost. Opportunistic routing protocols promising forwarding technique for various UWSNs. However, many opportunistic suffer from void problem in sparse scenarios. Hop count-based inherently alleviate this by periodically maintaining topological inf...

In setting up an underwater acoustic network the first and foremost task is node deployment. In underwater acoustic sensor networks, localization is one of the most important technologies to increase the coverage area and also to reduce the energy consumption of the node. Localization plays a critical role in many applications. This paper aims at analysing the node deployment strategies on loca...

Underwater wireless sensor networks (UWSN), similar to the terrestrial sensor networks, have different challenges such as limited bandwidth, low battery power, defective underwater channels, and high variable propagation delay. A crucial problem in UWSN is finding an efficient route between a source and a destination. Consequently, great efforts have been made for designing efficient protocols ...
