Abstract: Underwater acoustic sensor networks (UASNs) play a crucial role in marine data collection. However, due to harsh underwater channel conditions and the finite energy supply of sensor nodes ...

Abstract: In this paper, the problem of relay node placement in heterogeneous wireless sensor networks (WSNs) is addressed. As all nodes are energy limited, placement strategies aimed at minimizing ...

Reactive oxygen species (ROS) homeostatic pathways in microbes operate instant and feedback-regulated adjustments of intracellular ROS concentration. They use redox sensors that 'measure' ROS ...
