Power optimization in two-tier networks
International audience
A future cellular network demands a new architecture that can facilitate the autonomous deployment of the infrastructure similar to Wi-Fi. A novel method of deploying a cellular network has been introduced with small cellular base stations, or femtocells, autonomously deployed by users in an underlay macro-cellular network. This autonomous cellular concept allows the network to grow in an organic manner, which reduces the traditional work on infrastructure installation, network configuration and maintenance. To this end, we propose hereafter an intelligent and autonomic system for power control in the femtocell context. The first simulation results seem to confirm the advantage of our solution in reducing energy consumption.

Transparent real time service on connected train
International audience
In order to achieve the everywhere at anytime Internet, connection to the network must be available even inside cars, trains and buses, without disruption of service. In order to reach this objective, intelligent communications are now considered necessary and will play an increasing role in the modern Transportation Systems. As train speeds increase, wireless communications between devices on the train and the outside encounter difficulties, and maintaining communication quality is a major challenge. This paper, propose a new multihomed solution for transparent internet access in trains through secure handoff anticipation.

Improved relay selection for decode-and-forward cooperative wireless networks under secrecy rate maximization
International audience
Privacy and security have an increasingly important role in wireless networks. A secure communication enables a legitimate destination to successfully retrieve information sent by a source, while it disables the eavesdropper (illegitimate destination) to interpret the intercepted information. Physical (PHY) layer security approaches for wireless communications can prevent eavesdropping without encryption. It exploits the physical characteristics of the wireless channel in order to transmit messages securely. They are typically feasible when the source-destination channel is better than the source-eavesdropper channel. Cooperative schemes are a means to improve the performance of secure wireless communications. We propose an improved relay selection scheme, based on source-eavesdropper channel SNR restriction, that will guarantee the best secrecy rate at the destination under QoS condition. Performance has been studied in terms of secrecy rate, outage probability and average error probability. Simulations shows that the proposed scheme outperforms in terms of the secrecy rate at the destination when compared to techniques in the literature.

A QoS based Resource Allocation in Femtocell Networks
International audience
LTE has been identified as a new wireless standard by the 3rd Generation Partnership Project (3GPP) which is using the VoIP to transmit the voice services and packet the data for all services. Traffic scheduling plays an important role in LTE technology by assigning the shared resources among users in the most efficient manner. The main objective of this paper aims to design an efficient scheduling algorithm for LTE standard. It can not only obtain the high system performance but also maintain the proportional fairness. Each user is allocated the requested resource according to the predefined QoS parameters. The scheduling algorithms performances on the downlink were measured using a MATLAB based system level simulation.

Energy Saving by Handoff Classification in Femtocells Network
International audience
A femtocell is a radio equipment hich aims to improve the quality of the telecommunications network in customers' homes and / or in places that do not support the coverage of macro network. We focused our work on the issue of saving the energy consumed by femto-cells. In this paper, we introduce an energy efficient solution, to the cited issue, based on the removal of unwanted mobility events by classifying them according to their probabilistic importance in the context of BWA (Broadband Wireless Access) networks. We derived the analytical model of the solution. The first simulation results seem to confirm the advantage of our solution in reducing energy consumption.
