Special Sessions

CAMAD 2017 - Special Sessions


The CAMAD 2017 technical program will includes seven special sessions. Their objective is to complement the regular program with new or emerging topics of particular interest gravitating on interdisciplinary research. Submission deadlines can be found below for each one of the CAMAD 2017 special sessions.


  • 5G: An Era of Agile, Brisk and Superfluid Networking

    Special Session Chairs

    George Tsolis, Citrix Systems Inc.

    Christos Tselios, Citrix Systems Inc.

    Deadline: March 12 - Call for papers

    Scope
    The advent of 5G Networks introduces significant challenges in almost every link of the network value chain. The demand for seamless connectivity, extremely low latency, high-speed data transfer and energy efficiency along with the exponential increase of interconnected devices will shape an ecosystem with such complexity that enforces the replacement of almost every current standard.
    5G Network design aims to mitigate problems and shortcomings of today’s networks, such as long service instantiation times, resource over-provisioning for meeting peak subscriber demand, and dependence on obsolete and cost-ineffective hardware devices. This intention leads to an increasing need for networking briskness and agility that can be attained via the architectural decomposition of network elements and network services into basic, reusable primitives as well as the virtualization of network processing functions, which will further enhance the superfluid and holistic nature of the proposed ecosystem.
    In this respect, this Special Session aims at providing a forum where researchers, engineers, and practitioners may discuss the latest advances on architectures, algorithms, abstractions, and technologies for briskness, flexibility, and agility in 5G networking.

  • Towards network anticipation, SDN-based resource allocation, and resource sharing

    Special Session Chairs

    Di Yuan, Linköping University, Sweden

    Deadline: March 20 - Call for papers

    Scope
    Internet traffic is continuously growing exponentially. Meanwhile, the explosive growth of the number of connected devices, backed by applications in the growing Internet of Things, places Machine-to-Machine (M2M) communications in the spotlight. Future networks are therefore now called to support applications with requirements ranging from guaranteed delivery of low throughput and low latency flows (M2M) to ones with very high throughput with low delay (4K live streaming). However, the current state of the art shows that scalable solutions are not really feasible. New areas need to be explored and new techniques further developed.
    Taking into account the impact of prediction on the users’ demand and availability of network resources could be one direction. By predicting and adapting to upcoming events at various time scales, an anticipatory-enabled network dramatically improves the operation quality and efficiency in comparison to the existing systems. On the other hand, wireless caching and distributed resource management have become core research aspects for the upcoming 5G technologies, with potential for significant benefits. Additionally, due to the massive access of the medium in the 5G era and in the IoT scenarios, more flexible and distributed protocols have to be deployed, focusing on short packets at very high rates. In such protocols the nodes should be auto-configurable without centralized operations. The purpose of this special session is to bring together researchers focusing on resource management and optimization within the context of anticipatory networking for the 5G and beyond, for large scale networks.

  • Heterogeneous and Small Cell Networks

    Special Session Chairs

    Nikolaos Pappas, Linköping University, Sweden

    Xiaoli Chu, University of Sheffield, UK

    Deadline: March 20 - Call for papers

    Scope
    Broadband mobile networks experience exponential traffic growth. It is predicted that this trend will continue in the next five to ten years with an estimated compound annual growth rate of 0.6 to 1.0. Hence the (mostly data) traffic carried by a mobile operator’s network in 2022 could be over 1000 times of that in 2012. This traffic growth presents a huge challenge to both the mobile industry and to academic researchers.
    Along with increased spectrum efficiency, spectrum bandwidth expansion and traffic offloading through WiFi, small cell deployment is regarded as one of the most promising ways to meet the use of broadband mobile service in both outdoor and in particular indoor scenarios in the next decade. The deployment of small cells in a macrocell coverage area leads to a multi-tier heterogeneous network (HetNet), in which a mix of access node types, such as macrocell, femtocell and relay, will co-exist. Despite the current research and development on small cell/HetNet from both industry and academia, there are still many challenges to be addressed and questions to be answered for successful small cell and HetNet deployment. These challenges range from the lack of fundamental understanding of HetNet network capacity to the need of Radio Access Network (RAN) Planning and Optimisation (P&O) tool for HetNet deployment involving both indoor and outdoor scenarios.
    The purpose of this special session is to bring together researchers from industry and academia focusing on capacity study, backhaul planning and optimization for HetNets and Small Cells.

  • Rich-Media Emergency Communications for Future Internet

    Special Session Chairs

    Ilias Politis, Hellenic Open University, Greece

    Dr. Evangelos Markakis, Technological Educational Institute of Crete, Greece

    Dr. Yacine Rebahi, Fraunhofer FOKUS, Germany

    Deadline: March 12 - Call for papers

    Scope
    In an effort to cope with the rapidly increasing demand for continuous multimedia communications anywhere, anytime and with any device, Telecommunication operators are trading legacy technologies for broadband All-IP based services that allow among others, immersive rich services, efficient and flexible architectures, as well as, improved user satisfaction and perceived Quality of Experience (QoE). Evidently, this transition affects current circuit-switched based emergency systems, which are required by 2020 to migrate to packet-switched networks and fulfil the corresponding Next Generation Networks (NGN) regulatory requirements. Specifically, next generation emergency services will be required to integrate rich-media emergency calls (i.e., combining voice, video and real-time text) over IMS/SIP architectures, in addition to providing the platform for incorporating health and environmental monitoring sensor data, IoT infrastructures, social media interaction and extension to eCall, in order to improve the coordination and awareness of call centres and first responders. Towards this end, new paradigms for distributed emergency management and decision making are required in order to minimise the response times, improve the efficiency of emergency resources allocation and optimise the outcome in cases of emergency situations. The proposed session is highly relevant to CAMAD 2017 workshop focus on 5G networking and beyond, since next generation emergency services, management and communication are currently being re-visited and re-designed in order to fit the 5G networking vision as well as, the new complex regulatory requirements arising due to the cloudification and virtualization of the communication infrastructure. The special session will provide the opportunity to the network operators, emergency services operators, industry and research community to exchange thoughts, keep track of the current progress, discuss and present novel ideas and working solutions on issues including security and privacy, extension to eCall, IoT and sensor data incorporation to emergency calls, interactions with social media and provide evidence on the migration towards NG122 and NG911 in EU and US respectively.

  • Communications and information processing for the smart grid

    Special Session Chairs

    Dionysis Xenakis, University of Athens, Greece

    John Vardakas,Iquadrat, Spain

    Deadline: March 20 - Call for papers

    Scope
    The smart electricity grid is recently enjoying increasing attention both in research and implementation. The need of delivering, in a cost-effective manner, high-quality robust and secure real-time smart energy/management solutions to a rapidly growing market is an important issue. The use of advanced solutions and technologies is considered as the fundamental enabler towards the main goal of reducing greenhouse gas emissions and to improve overall energy efficiency. Although some important steps have been made in this direction, new advanced solutions are required to fully exploit the benefits of new technologies in the area. This session aims at bringing together researchers from academia and industry, to meet and exchange ideas on recent research and future directions.

  • User-Centric Communications and Content Delivery

    Special Session Chairs

    Dr. Luigi Pomante, Università degli Studi dell'Aquila, Center of Excellence DEWS, Italy

    Dr. Dimitris Tsolkas, University of Athens, Greece

    Dr. Kostas Ramantas, Iquadrat, Spain

    Deadline: March 20 - Call for papers

    Scope
    The rapid growth of multi-modal media services, ranging from conventional video conferencing to interactive immersive experiences, necessitates user-centric methodologies and approaches in order to assess and evaluate the perceived multimedia quality. Towards this direction the key challenge is to understand Quality of Experience (QoE) notion and define QoE provisioning chains in the era of 5G networks, by incorporating advanced capabilities on: i) storage/computing/network resource management; ii) central service and network orchestration; iii) network softwarisation; and iv) Big data analytics. Although some important steps have been made in this direction, new advanced solutions are required towards: i) best match network performance metrics to end-consumers’ satisfaction level; ii) fully exploit QoE insights to take advantage of new technologies and networking tools; and iii) well define QoE-oriented business models and marketing schemes.

  • Fog Computing Technologies for the Internet-of-Things (Fog-IoT)

    Special Session Chairs

    Alexandros Fragkiadakis, FORTH-ICS, Greece

    Stefano Iellamo, FORTH-ICS, Greece

    Deadline: March 25 - Call for papers

    Scope
    The Internet-of-Things (IoT) is one of the most promising emerging technologies, aiming to interconnect billions of devices, and enabling a plethora of applications and services, spanning from environmental monitoring, eHealth and smart agriculture, to smart grids and connected vehicles. Considerable interest has been shown to smart cities where whole IoT ecosystems have been developed using multi-layer architectures consisting of Wireless Sensor Networks (WSNs) and backbone cloud systems.
    WSNs interconnect heterogeneous devices in terms of the software, hardware, and communication medium used. Very large portions of these networks usually include resource-constrained devices, referred as sensors or motes, with the role to collect various measurements (ambient humidity, light, noise, etc.). Despite the recent advances in hardware, these devices are still severe resource-constrained in terms of processing, memory, and storage. Furthermore, several inefficiencies of the networking protocols often lead to substantial performance degradation, thus, significantly affecting users’ quality of experience.
    5G is expected to become a significant enabler of IoT as it will be composed of flexible multi-tier, and scalable heterogeneous architectures, incorporating small cells and Wi-Fi offloading. Moreover, 5G will make IoT more effective and efficient in terms of spectral efficiency.
    Despite the expected advances of 5G in the context of IoT, the current architectural IoT model mainly includes WSNs that collect measurements, and cloud infrastructures for data storage, providing more resource-intensive operations like big data analytics, service creation and federation, etc. Nevertheless, this model cannot efficiently service modern IoT applications that require mobility support, geo-distribution, location awareness, low latency, etc.
    The new paradigm of fog computing aims to operate between the resource-constrained WSNs and the cloud, offering services like data offloading, real-time analytics, mobility support, real-time interactions, interoperability, etc. However, with fog computing, new challenges will arise related to network security, privacy, trust management and computation, embedded security, secure storage, identity management obfuscation, localisation, and interoperability.

Manuscripts should conform to the formatting and electronic submission guidelines of regular CAMAD 2017 papers. They will undergo the same review process as regular papers by at least 3 independent reviewers.
