Abstract

International audience; The paper presents the studies that have been led toward the integration of device-to-device (D2D) communications within LTE networks in the frame of the project ACCENTS (Advanced Waveforms, MAC Design and Dynamic Radio Resource Allocation for Device-to-Device in SG Wireless Networks) supported by the French National Research Agency. The solutions presented in this paper cover several aspects of D2D communications; they are the result of a close cooperation between four partners: Thales Communications and Security, CNAM, TeamCast and CentraleSupelec. Physical Layer aspects have been investigated, especially concerning waveforms envisioned for D2D communications within SG networks. Also, a new MAC protocol has been designed to address the issues raised by the integration of D2D transmissions within LTE cells. The solution coming out of the study guarantees a minimum QoS for both types of users (D2D users and regular users) and aims at reusing spectrum while offloading the burden on the base station.

4. Cross-layer signalling support for adaptive video encoding and transmission

Abstract

Following the joint source and channel coding paradigm, we propose an application controlling strategy to allow fast adaptation of multimedia transmission to the impairments of an IP wireless network by using a new cross-layer signalling architecture. To this purpose, a Rate-Distortion Optimization (RDO) algorithm based on hybrid Cauchy-Laplace distribution is presented. In order to support the adaptation and to enable the application controlling strategy by providing the necessary signalling information, a flexible and cloud computing based cross-layer event delivery entity is proposed. This entity provides a unified signalling architecture for accessing such information that cannot be accessed by using existing controlling mechanisms and which is necessary for the adaptation of the multimedia transmission. Information obtained through this event delivery entity is used by the RDO algorithm to define the parameters providing the best perceived quality at the receiver side in terms both of compression and optionally of error correcting redundancy insertion to minimize the error impact with a GOP adaptation rate. This technique is demonstrated here for H.264 streams.

Abstract

The provision of telemedicine services requires the usage of advanced and reliable communication techniques to offer diagnostically acceptable Quality of Experience (QoE) in the delivery of biomedical data between distant locations either using wireline or wireless access networks. To overcome the restrictions of conventional communication systems and to address the challenges imposed by wireless multimedia delivery and adaptation for healthcare applications, the FP7 ICT CONCERTO project proposes a cross-layer optimized architecture with all the critical building blocks integrated for medical media content fusion, delivery and access. In this poster we focus on the general architecture design of CONCERTO and present a sophisticated access network and inter-domain signalling framework with a distributed decision engine for cross-layer communication management and adaptation control of quality demanding interactive multimedia healthcare services

Abstract

The management of medical emergency, in particular cardiac emergency, requests prompt intervention and the possibility to communicate in real time from the emergency area / ambulance to the hospital as much diagnostic information as possible about the patient. This would enable a prompt emergency diagnosis and operation and the possibility to prepare the appropriate actions in the suitable hospital department. To address this scenario, the CONCERTO European project proposed a wireless communication system based on a novel cross-layer architecture, including the integration of building blocks for medical media content fusion, delivery and access. This paper describes the proposed system architecture, outlining the developed components and mechanisms, and the evaluation of the proposed system, carried out in a hospital with the support of medical staff. The technical results and the feedback received highlight the impact of the CONCERTO approach in the healthcare domain, in particular in enabling a prompt and reliable diagnosis in challenging medical emergency scenarios.
