Architectures of avionics networks, such as that of the Airbus A380, currently know important evolutions. This is principally due to the increase in the complexity of the embedded systems, in term of rise in number of integrated functions and their connectivity. The evolution of Switched Ethernet technologies allows their implementation as an avionics(More)
Multi-Point to Multi-Point Traffic Engineering (MP2MP-TE) leads to an important scalability in Multi Protocol Label Switching-Traffic Engineering (MPLS-TE) networks. This paper emphasizes on the support of Fast-reroute (FRR) in MPLS-TE networks by using MP2MP bypass TE-tunnels. Hence, one MP2MP bypass TE-tunnel can be used to protect several primary(More)
In this paper, we present a new detector for cognitive radio system based on the Canonical Correlation Significance Test (CCST). Unlike existing CCST approaches, which can only be applied on Multi-Antenna System (MAS), our algorithm can be extended for both Single Antenna System (SAS) and MAS. For SAS, the proposed algorithm exploits the time diversity of(More)
In this paper, Principal Component Analysis (PCA) techniques are introduced in the context of Cognitive Radio to enhance the Spectrum Sensing performance. PCA step increases the SNR of the Primary User's signal and, consequently, enhances the Spectrum Sensing performance. We applied PCA as a combination scheme of a multi-antenna Cognitive Radio system.(More)

Spectrum Sensing is the main part in the Cognitive Radio system. In fact many researches have been realized the last decade, and several techniques have been proposed to perform the Spectrum Sensing. This manuscript deals with this subject by presenting the most used techniques, by categorizing them as Cooperative and Blind, according to their requirements.(More)
We propose a method to compute point to multipoint (P2MP) traffic engineered paths that cross several MPLS domains. It relies on the use of multiple Path Computation Elements (PCEs), in the goal of calculating a P2MP tree along a given tree of domains by using a recursive path computation technique. Indeed, the calculation is started by the PCEs of the(More)
