Abstract: This paper addresses the target coverage problem in wireless sensor networks with adjustable sensing range. Communication and sensing consume energy, therefore efficient ...
— Sensor networks consist of autonomous nodes with limited battery and of base stations with theoritical infinite energy. Nodes can be sleep to extend the lifespan of the networ...
Owing to numerous potential applications, wireless sensor networks have been the focus of a lot of research efforts lately. In this note we study one fundamental issue in such net...
—We consider information retrieval in a wireless sensor network deployed to monitor a spatially correlated random field. We address sensor scheduling in each data collection und...
We study minimum-cost sensor placement on a bounded 3D sensing field, R, which comprises a number of discrete points that may or may not be grid points. Suppose we have types of se...
