    Consensus and relation networks
    (11th International Conference on Innovative Internet Community Systems (I2CS 2011), 2011) Ahat, Murat; Bennani, Omar; Bui, Marc; Amor, Soufian Ben
    In this paper, we propose an extension to bounded confidence model which is a nonlinear opinion dynamics model. The goal of this new extension is to emphasize the underlying network structure of the model, since in real life network structure plays an important , if not vital, role in opinion dynamics. And with simulation results, we show how networks, such as grid and scale-free, affect the consensus formation in bounded confidence model separately as well as together.

    Optimizing mobile networks connectivity and routing using percolation theory
    (10th International Conferenceon Innovative Internet Community Systems (I2CS) – Jubilee Edition 2010 –, 2010) Amor, Soufian Ben; Bui, Marc; Lavallée, Ivan
    Mobile Ad-hoc NETworks (MANETs) are complex systems presenting a phase transition phenomenon : an abrupt change in the behavior of the network around a critical value of a certain key parameter. The reliability and connectivity of MANETs depend on their size and on the efficiency of the routing protocol. In this paper we propose a new approach in MANETs modeling, combining percolation theory and epidemic algorithms. Using percolation theory we show the existence of a connectivity threshold (in a square lattice) needed to guarantee the communications in the network, in particular when the number of direct links are limited. Epidemic algorithms are used to provide a good propagation of information in the network wile minimizing the resources cost (energy, number of messages...).
