Implementation of a Wireless Mesh Network of Ultra Light MAVs with Dynamic Routing

Dario Floreano, Bixio Rimoldi, Jean-Christophe Zufferey, Alberto Jimenez Pacheco, Yannick Gasser

This paper describes the implementation and characterisation of a mobile ad-hoc network (MANET) of ultra-light intelligent flying robots. The flying nature of the network makes it suitable to collect or disseminate content in urban areas or challenging ter ...

Computation in Multicast Networks: Function Alignment and Converse Theorems

Michael Christoph Gastpar, Naveen Goela

The classical problem in network coding theory considers communication over multicast networks. Multiple transmitters send independent messages to multiple receivers which decode the same set of messages. In this work, computation over multicast networks i ...

Broadcasting and Multicasting Nested Message Sets

Shirin Saeedi Bidokhti

Finding theoretical limits on the performance of communication systems and designing schemes to achieve them is one of the fundamental questions in information theory. While the theory of point-to-point communication is well-investigated, most problems hav ...

Signaling and Reciprocity

Wojciech Galuba

Complex networks exist for a number of purposes. The neural, metabolic and food networks ensure our survival, while the social, economic, transportation and communication networks allow us to prosper. Independently of the purposes and particularities of th ...

Information-theoretic secrecy for wireless networks

Etienne Perron

The aim of information-theoretic secrecy is to ensure that an eavesdropper who listens to the wireless transmission of a message can only collect an arbitrarily small number of information bits about this message. In contrast to cryptography, there are no ...

Local restoration for trees and arborescences

Laura Sanità

Protocols belonging to the Spanning Tree Protocol (STP) route traffic demands on tree topologies that are evaluated through shortest path procedures. In this paper we deal with the problem of assigning costs to the arcs of a network in order to guarantee t ...

User-level Internet tomography and overlay routing

Xuan Hung Nguyen

In this thesis, we study methods to detect, localize and overcome performance problems experienced by end-users in communication networks. These problems are extremely difficult to solve when the only available information are end-to-end data. We first con ...

Network Resource Allocation for Competing Multiple Description Transmissions

Suhas Diggavi

Providing real-time multimedia services over a best-effort network is challenging due to the stringent delay requirements in the presence of complex network dynamics. Multiple description (MD) coding is one approach to transmit the media over diverse (mult ...

Achievable Flows on Orthogonal Information Networks

Dinkar Vasudevan

We examine routing over two classes of orthogonal information networks. The first is a relay network with orthogonal inputs. The nodes in this network do not broadcast, but communicate to the different nodes via independent inputs. There is multiple access ...

Practical Approaches for Software Components Integration in Telecommunications

Sébastien Rumley, Christian Gaumier

Nowadays, advances in telecommunication network design and performance analysis often rely on dedicated software tools. Unfortunately, developing new tools is a very time and resources consuming activity. To rationalise development costs, existing applicat ...
