Final Report Summary - CROWN (Cross-layer Research on Green Cooperative Cognitive Radio Networks and Services)

• Summary Description of the CROWN Project Objectives:
The overall objective of the CROWN project is to accelerate the transfer and deployment of research
knowledge between European countries and China in order to obtain better understanding of
cognitive radio wireless networks and services in terms of various aspects such as energy
efficiency/green, cooperativeness, and cross-layer design from both the physical layer and the upper
layers of wireless networks. In particular, the transfer of knowledge, mainly as a result of
researcher’s mobility, will focus on a new vision of green Cooperative CR paradigm or CCR. This
new vision advocates the seamless integration of three important aspects of modern wireless
communication systems, i.e., green, cooperativeness and cross-layer. It is the aim of this project to
explore a systematic way to bring together these features into a CCR network so as to maximize its
effective network throughput (excluding signalling overhead) while staying green. In the meanwhile,
the design of the CROWN network architecture will also take into consideration the new trend of
services (e.g., increasing more video streaming) and their provisioning mechanisms (such as SDN,
NFV, cloud computing). Content-, user-, and context- awareness will be considered as much as
possible to envisage a new CCR era where mobile network operators, service providers and end users
all benefit. Our CROWN staff exchange programme will also help develop new research links and
deepen and strengthen the current research links amongst the partners and help build up long-term,
world-class research in this exciting new research field of future Green Cognitive Wireless Network
technology.

• Work Performed Since the Beginning of the CROWN Project:
All the project partners got actively involved in the project work programmes and achieved the planned research aims.
All the planned project Deliverables (D1.1, D1.2, D2.1, D3.1, D3.2, D4.1, D4.2 and D5.1) had already been completed and been all submitted successfully.
All the planned objectives, milestones, deliverables and technical goals had been achieved.

• The Main Results Achieved by CROWN Project So Far:
# Specifications of the new requirements for green CCR networks are obtained from across different
network layers, i.e. in the cross-layer manner;
# Definition of two use cases scenarios are given that can reflect the essence of the CROWN
objectives and solutions;
# Designs of the overall methodologies and green CCR network architecture are achieved;
# Coordination of the system design activities are carried for WP2-WP5 to ensure their
smooth development and mutual interactions.
# D2.1 final deliverable has already been submitted to EC.
# Specification of green CCR physical and MAC layers modelling have been created;
# D3.2 – Final Report on CCR Physical Layer Design had already been submitted to EC.
# Specification of green CCR upper layers design and modelling have been created;
# D4.2 – Final Report on CCR Cross-layer Design had already been submitted to EC.
# D5.1 – Final Report on Experimental and Evaluation Results had already been submitted to EC.
# The planned staff exchange activities are generally well performed;
# Many high-quality relevant research publications have been published/accepted by/submitted to the
journals and conferences;
# The CROWN consortium members have organized nine Journal Special Issues from our research
and are to organize various International Research Conferences/Workshops;
# Carried the industrial visits to the companies Rinicom Ltd and HW Communications Ltd;
# Offered the training and dissemination to the PhD, master and final year UG students and wide
audience.

• The Expected Final Results and Their Potential Impact and Use: (including the socio-economic
impact and the wider societal implications of the project so far).
The expected final results of the CROWN project are: 1) New cross-layer system and network
architecture designs of green cooperative cognitive wireless networks; 2) Energy efficient and
cooperative physical layer protocols and modeling; 3) Cognitive upper layer protocols and modeling;
4) Testbed experiments evaluation. 5) High impact journal papers and conference papers. 6) Journal
special issues and Conference/workshop organizations.
The CROWN project will have high impact and potential to impose strong strategic impact on the
European markets of telecommunications/networks and information technology. With its research
territory covering future energy-efficient communications network technologies and future mobile
Internet, CROWN will help bring a new, cooperative and flexible green wireless communication
infrastructure and services to the major stakeholders (mobile network operators, manufacturers,
service providers and content providers) in Europe. This will significantly facilitate the development
and deployment of such network infrastructure and its associated technologies in not only European
countries but also other countries such as China. China has the world’s biggest telecommunication
and network market, especially when the scale of mobile communications facilities and users are
concerned. On the mobile communication front, China has its own broadband 3G and beyond
standards, which has attracted almost every single major communication and network equipment
vendor worldwide. On the fixed network front, China is also very active in standardisation such as
IETF, ITU, etc. Fundamentally, China is too big a market to be missed out by Europe as far as the
ICT (information communication technologies) is concerned. A people mobility project with China
that is targeting this massive area of future green communications & mobile Internet is of great
strategic importance to ERA.
