For impulse-radio ultra-wide band (IR-UWB) networks without global synchronization, the first step for correct packet reception is packet detection and timing acquisition: Before recovering the payload of the packet, the destination must detect that the pa ...
We consider streaming video content over an overlay network of peer nodes. We propose a novel streaming strategy that is built on utility-based packet scheduling and proportional resource sharing in order to fight against free- riders. Each of the peers em ...
A novel routing algorithm, named Balanced Adaptive Routing Protocol (BARP), is proposed for NoCs to provide adaptive routing and ensure deadlock-free and livelock-free routing at the same time. By evenly distributing input packets of a router among all its ...
According to different kinds of connectivity, we can distinguish three types of mobile ad-hoc networks: dense, sparse and clustered networks. This paper is about modeling mobility in clustered networks, where nodes are concentrated into clusters of dense c ...
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 ...
Several computer tools addressing the routing and wavelength assignment (RWA) problem are available today within the research community. However, these tools have low flexibility and are difficult to use for remote or casual users. This paper shows how to ...
A Disruption-Tolerant Network (DTN) attempts to route packets between nodes that are temporarily connected. Difficulty in such networks is that nodes have no information about the network status and contact opportunities. The situation is different in publ ...

Modern Byzantine fault-tolerant state machine replication (BFT) protocols involve about 20.000 lines of challenging C++ code encompassing synchronization, networking and cryptography. They are notoriously difficult to develop, test and prove. We present a ...
The longevity of wireless sensor networks is a major issue that impacts the application of such networks. While communication protocols are striving to save energy by acting on sensor nodes, recent results show that network lifetime can be prolonged by fur ...
We investigate the usability of the Artificial Immune Systems (AIS) approach for solving selected problems in computer networks. Artificial immune systems are created by using the concepts and algorithms inspired by the theory of how the Human Immune Syste ...
