Scalable, reliable underwater communication is still a major challenge limiting the deployment of large-scale cooperative underwater systems, such as swarms of AUVs, which generally rely on frequent updates from surrounding units for control and mission ob ...
Network coding enables novel network functionalities and thus offers a wider canvas of choices when optimizing an information flow problem. In this paper, we examine the simplest possible information flow problem, a unicast connection, and explore what we ...
Modelling, dimensioning and performance analysis of optical backbone networks is the main concern of this thesis. Modelling consists in representing a network under a abstract form, simpler and easier to analyse, the model. Dimensioning is achieved when ne ...
In biological systems, animals exhibit organized behavior that arises from localized interactions. The interaction is implemented through information exchange, either directly or indirectly. Adaptive networks, consisting of a collection of nodes with learn ...
Networked computing environments are subject to configuration errors, unauthorized users, undesired activities and attacks by malicious software. These can be detected by monitoring network traffic, but network administrators are overwhelmed by the amount ...
The dynamic traffic assignment (DTA) problem is to find the state of a transportation system where demand (travel behavior) and supply (network performance) are mutually consistent. The difficulty of solving this problem with mathematical rigor led to the ...
In this paper, we study the problem of optimizing (fine-tuning) the design parameters of large-scale traffic control systems that are composed of distinct and mutually interacting modules. This problem usually requires a considerable amount of human effort ...

Network administrators are faced with a large amount of network data that they need to sift through to analyze user behaviors and detect anomalies. Through a network monitoring tool, we obtained TCP and UDP connection records together with additional infor ...
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 ...
Public key cryptography can introduce significant processing delays in vehicular communication platforms. This can lead to serious performance issues, especially in the case of multi-hop Inter-Vehicle Communication. In this paper we propose Adaptive Messag ...
