    Information technology for Enhancing Disaster Management
    (2009-05-23) Nouali-Taboudjemat, Nadia; Bouchama, Nadir; Bendjoudi, Ahcène; Babakhouya, Abdelaziz; Yahiaoui, Saïd; Belhoul, Yacine; Zeghilet, Houda; Guellati, Nabil
    Responding to natural or man-made disasters, in a timely and effective manner, can reduce deaths and injuries as well as economic losses. Predicated on the assumption that better information leads to efficient decision-making and more effective performance of crisis response, research projects applying advanced information technology solutions to the crisis management field have emerged. This paper provides an overview of most recent projects, in this area, all over the world. Furthermore, the study highlights that using scalable and robust IT solutions can drastically facilitate access to theright information, by the right individuals and organizations,at the right time.

    The Effects of Interference on Video Quality Over Wireless Sensor Networks
    (Elsevier, 2013) Zeghilet, Houda; Baziz, Yacine; Badache, Nadjib
    Multi-path routing appears to be an essential feature for supporting the characteristics of wireless multimedia sensor networks. In fact, using multiple paths between the source and the destination can provide adequate network resources required by such networks. However, the effect of wireless interferences between paths severely affects the performance of this approach. In this paper, we propose a simple interference-aware multipath routing protocol and study the effects of inter-path interferences on the received video quality in the context of wireless multimedia sensor networks. We show, through simulations, that minimizing interferences between the transmission paths can provide necessary bandwidth to support multimedia applications when small frame rates are used.
