Ocean exploration, through the development of oceanobservation systems, has been
recognized as a key step toward a fuller understanding of life on Earth. With the rapid …

Due to the long propagation delay and high error rate of acoustic channels, it is very
challenging to provide reliable data transfer for time-critical applications in an energy …

Energy optimized Path Unaware Layered Routing Protocol (E-PULRP) for dense 3D
Underwater Sensor Network (UWSN) is proposed and analysed in this paper. In the …

We introduce a new graph-theoretic approach to image segmentation based on minimizing
a novel class of'mean cut'cost functions. Minimizing these cost functions corresponds to …

In an energy-constrained underwater system environment it is very important to find ways to
improve the life expectancy of the sensors. Compared to the sensors of a terrestrial Ad Hoc …

The design of routing protocols for Underwater Wireless Sensor Networks (UWSNs) poses
many challenges due to the intrinsic properties of underwater environments. In this paper we …

Designing of media access control (MAC) protocol is one of the major challenges in
underwater acoustic sensor networks. Because of the long and changeful propagation …

Underwater acoustic wireless sensor networks (UAWSNs) have many applications across
various civilian and military domains. However, they suffer from the limited available …

A medium access control (MAC) protocol permits the nodes to access the shared medium by
providing contention resolution mechanism. The design of MAC protocol in ad hoc networks …

In underwater wireless sensor networks (UWSNs), media access control (MAC) is important
because it may have a significant impact on network performance; however, the complex …
