Today's mobile battery-powered communication devices require that users access chargers via wired and, recently, wireless recharging facilities. For a device departing from a location with a given energy ``budget'', a plausible strategy is to seek a charger location once the energy is exhausted....

We consider the problem of estimating the location of people as they move and work in indoor environments. More specifically, we focus on the scenario where one of the persons of interest is unable or unwilling to carry a smartphone, or any other âwearableâ device, which frequently arises in...

Today, with gaming technology advancing by leaps-and-bounds, we are witnessing the proliferation of games for entertainment and education. Users can easily record their real-world experiences, through affordable smart phones, equipped with accelerometers, GPS receivers, compasses, and cameras....

We propose the use of embedded in-wall thermoelectric harvester to power the nodes of a wireless sensor network. We exploit significant temperature differences of indoor and outdoor environments in cold climates. We use real measurements to evaluate the use of the temperature difference as a...

Wireless sensor networks have become a very important tool for monitoring physical and environmental conditions over a wide area. These networks are distributed collections of small sensor nodes. Typically, sensor nodes collect data that must converge to a single sink location, possibly across...

A cyber-physical system (CPS) is composed of interacting physical and computational components. CPS research addresses the combined sensing and actuating to monitor and control a CPS. Simulation techniques are used in advance of costly CPS deployments to provide sufficient understanding of the...

The objective of this thesis is the study and implementation of a Vehicular Delay Tolerant Network (VDTN) system for a fleet of vehicles, and the evaluation of its data carrying potential. The implementation relies on commodity hardware and communication using "WiFi" (IEEE 802.11) transceivers....

In this thesis, we focus on topics relevant to developing and deploying large-scale wireless sensor network (WSN) applications within real dynamic urban environments. Given few reported experiences in the literature, we designed our own such network to provide a foundation for our research. The...
