Propagation models are used to abstract the actual propagation characteristics of
electromagnetic waves utilized for conveying information in a compact form (ie, a model with …

Severe energy constraints of battery-powered sensor nodes necessitate energy-efficient
communication in Wireless Sensor Networks (WSNs). However, the vast majority of the …

In infrastructure-less sensor networks, efficient usage of energy is very critical because of the
limited energy available to the sensor nodes. Among various phenomena that consume …

Wireless underground sensor networks (WUSNs) enable many applications such as
underground pipeline monitoring, power grid maintenance, mine disaster prevention, and oil …

With the rapid development of underwater acoustic modem technology, underwater acoustic
sensor networks (UWASNs) have more applications in long-term monitoring of the …

IT governance research has been largely normative and has provided a great deal of useful
insight into what effective IT governance should be. What has received less attention is an …

As over 70% of the earth's surface is covered by water, it is desirable to deploy underwater
sensor networks (UWSNs) to support oceanic research. UWSNs use acoustic waves and are …

We consider a hybrid TDMA/CDMA wireless sensor network (WSN) and quantitatively
investigate the energy efficiency obtained by combining adaptive power/rate control with …

In this paper, we address the problem of minimizing energy consumption in a CDMA-based
wireless sensor network (WSN). A comprehensive energy consumption model is proposed …

Position information is often one of the key requirements for a wireless sensor network
(WSN) to function as intended. Due to drawbacks in using GPS or having to manually setting …
