Abstract: When there are multiple barriers in a wireless sensor network (WSN), the sleep-wakeup schedule can be used to alternate working barriers to extend the overall network lifetime. However, when ...

Abstract: A relaxation of the general infinite horizon sensor scheduling problem for state estimation in linear time-invariant systems is presented. The optimal schedule is assumed to be periodic, and ...

A new analysis has revealed that plant-derived cellulose has emerged as a working platform for sensors that measure soil moisture, nutrients, stress, and disease directly in the field. That reframes ...
