We study the problem of providing a sensor node with an accurate estimate of the current time, from a novel prospective which is complementary to the well
For economic reasons sensor networks are often implemented with resource constrained micro-controllers and low-end radio transceivers. Consequently, communication is inherently un...
— We consider the problem of gathering data from a sensor network using mobile elements. In particular, we consider the case where the data are produced by measurements and need ...
