EDWiN : leveraging device-to-device communications for Efficient data Dissemination over Wi-Fi Networks
International audience
An emerging usage is to rely on mobile devices (Smartphones or tablets) for large-scale events. They can be used for many applications like live voting or chatting, but also to access all the data related to an event. However, in such case, handling mobile devices trying to access data simultaneously is difficult. A Wi-Fi access point can only handle a limited amount of devices. Current solutions, relying on pre-loading data on the devices or over-sizing the network equipments are not satisfying and are not even always possible. We propose an approach that leverages the capability of mobile devices to interact directly through device-to-device (D2D) communications. Our solution can be tuned to choose the right level of parallelization to cope with radio interferences, it also provides the ability to adjust the trade-off between efficiency and energy consumption. We evaluate our approach using a discrete event simulator. The results show that our approach using D2D communications brings a 30% gains with our simulation.

SDN-based Wi-Fi Direct Clustering for Cloud Access in Campus Networks
International audience
Mobile cloud is changing the way to enroll teaching activities in university campus. Lectures and lab sessions can be carried out directly from tablets in a class room by accessing a server in the cloud. In this paper, we address the problem of high density cloud access with wireless devices in campus networks. We propose to use Wi-Fi Direct clustering to solve the problem of Quality of Service (QoS) degradation when a high number of wireless devices want to access a content in the cloud at the same time. A centralized software-defined network controller is used in our proposed architecture to capture the network state and organize the Wi-Fi Direct groups. The optimized number of clusters can be calculated in function of the number of devices in the room. By simulations, we show that we can provide a better QoS in terms of download time and application's throughput by reducing the interference in this dense wireless network environment.

Toward heterogeneity-aware device-to-device data dissemination over Wi-Fi networks
International audience
In the last few years, there has been an explosive growth of the number of mobile devices. This has come with a plethora of new applications and usages. Among these new usages, there are many occasions for which a content has to be disseminated to a large number of mobile devices (e.g., large-scale events providing a multi-media support, video streaming, ...). To cope with network bandwidth limitations, new approaches, leveraging device-to-device (D2D) communications have emerged. Obviously, one of the main problem that D2D-based approaches have to face is the energy consumption. Furthermore, there is usually a huge heterogeneity among the devices: some may benefit of a good, fully charged battery while others may have only a couple of hours left before a power failure; the network bandwidth can also differ a lot. In this paper, based on a previous work, we propose an approach to take into account devices heterogeneity while disseminating data using D2D communications. Our simulations show that it is possible to spare the weakest batteries without wearing too much the good ones nor degrading too much the performance. Furthermore, taking into account the devices bandwidth capabilities can help to increase the dissemination speed.
