Redundancy Model and Boundary Effects Based Coverage-Enhancing Algorithm for 3D Underwater Sensor Networks

open access: yesInternational Journal of Distributed Sensor Networks, 2014
In the study of three-dimensional underwater sensor networks, the nodes would produce changes in perception range under the influence of environmental factors and their own hardware. Requesting all nodes completely isomorphic is unrealistic.

What Is a Wireless Sensor Network?

open access: yesEDIS, 2018
A wireless sensor network (WSN) is a system designed to remotely monitor and control a specific phenomenon or event. This new 2-page fact sheet discusses the advantages that the WSN has over traditional stand-alone sensors and controllers, power consumption and conservation, and WSN technologies.
