The focus of this thesis is on communication over cooperative information networks. In the first half of the thesis, we consider lossy source coding problems where a relay assists in the communication of a source stream between two terminals. The following ...
Wireless Sensor Networks (WSNs) are composed of a large number of very small devices used for biomedical or environmental monitoring applications. These devices measure various natural processes at different locations, and cooperate in order to aggregate t ...
In this paper, we present Ishtar, a lightweight and versatile collection of software for remote data access and monitoring. The monitoring architecture is crucial during the development and experimentation of autonomous systems like Micro Air Vehicles. Ish ...
Most papers addressing consensus in wireless ad hoc networks adopt system models similar to those developed for wired networks. These models are focused towards node failures while ignoring link failures, and thus are poorly suited for wireless ad hoc netw ...
Wireless sensor networks are ideally built on low-cost, low-complexity nodes that have a low power consumption to guarantee a long network lifetime. These are all properties that can potentially be achieved with impulse radio ultra-wide band (IR-UWB). In a ...
Solving consensus in wireless ad hoc networks has started to be addressed in several papers. Most of these papers adopt system models similar to those developed for wired networks. These models are focused towards node failures while ignoring link failures ...
The expansion of 3D real-time simulations (3DRTS) into millions of homes together with the technical progress of computers hardware force to approach software developments for 3DRTS from different perspectives. From an historical standpoint, 3DRTS started ...
In this paper we will propose a relaying scheme for wireless multi-hop networks. It is based on collaboration of intermediate relays at network layer to forward useful side information in place of dumbly forwarding packets. In our scheme we assume that the ...
It is now commonly accepted that the unit disk graph used to model the physical layer in wireless networks does not reflect real radio transmissions, and that a more realistic model should be considered for experimental simulations. Previous work on realis ...
We consider networks of impulse-radio ultra-wide band (IR-UWB) devices. We are interested in the architecture, design, and performance evaluation of these networks in a low data-rate, self-organized, and multi-hop setting. IR-UWB is a potential physical la ...
