In this paper, we present TrainSense, a novel infrastructure to support the development and testing of mobile sensing applications. TrainSense merges a mote and a model train into a single mobile unit, and enhances the basic model train infrastructure with several important features required for the evaluation of mobile scenarios. First, we develop a(More)
An important basis of many smart city applications is knowledge about the location of persons and objects. In outdoor environments, this knowledge can be acquired reliably on a global scale using the well-known Global Positioning System (GPS). In indoor environments, both the availability and reliability of GPS is significantly limited. This, in turn, has(More)
OBJECTIVE Examination of whether health care consumption of Moroccan or Turkish insured under the Dutch national health system varies from that of the indigenous Dutch population. DESIGN Retrospective, transverse. METHOD Research was performed on the database of an insurance company concerning medication, referrals to a specialist, admissions to the(More)
This paper presents a simple routing protocol based on topology control that improves the lifetime of a wireless sensor network in the usual convergecast pattern, by allowing the nodes to choose between two predefined power-levels to forward data towards the sink. The proposed protocol takes advantage of non-homogeneous topologies, where the nodes are(More)
Node reprogramming serves as an important service to support post-deployment code management and maintenance for unattended wireless sensor networks or autonomous robotics applications. We present a prototype of a design framework called SHAMPU, a <i>S</i>ingle chip <i>H</i>ost for <i>A</i>utonomous <i>M</i>ote <i>P</i>rogramming over <i>USB</i>. A SHAMPU(More)
