CALL FOR PAPERS
2nd Workshop on Cooperative Heterogeneous Networks (coHetNets)
July 30 - August 2, 2012, Munich, Germany



https://sites.google.com/site/cohetnet2012/

Collocated with:
International Conference on Computer Communication Networks (ICCCN 2012)





The proliferation of new applications, e.g. mobileTV, Internet gamming,
large file transfer, and the development of user terminals, e.g., smart
phones, notebooks, has dramatically increased user traffic and network load.
Moreover, with the number of wireless subscribers expected to triple over
the next five years, it is obvious that  current networks will not be able
to satisfy customer demands in the near future.
In order to meet this traffic growth and
provide service to their
customers, vendors and operators are working on the development of new
technologies and cellular standards. Within them, heterogeneity in network
deployment has been heralded as the most promising way of increasing both
the coverage and the capacity of future wireless systems.
Thus, it is expected that new elements such as remote radio heads,
picocells, femtocells, and relay nodes will
be deployed overlying macrocells. Therefore, future networks are expected
to be heterogeneous. In this way, networks will be closer to users, and
system capacity will be enhanced through a better spatial spectrum reuse.
However, although HetNets are envisioned to support the increasing data
traffic demand and meet the requirements imposed for the fourth generation
of mobile networks, they also lead to new technical challenges never faced
before. For example, due to the larger number of cells and thus of cell
boundaries, the management of interference becomes an intricate problem.
Since centralized network planning and optimization cannot deal with the
individualistic nature of user-deployed  cells, e.g., femtocells, a key to
the success of HetNets is the cooperation between nodes in a decentralized
and distributed manner.
Such cooperation is the only way to ensure a proper network operation.
However, cooperation is not easy to achieve due to different issues and
threats imposed by the network itself, e.g., limited back-haul
capabilities, dynamics of traffic and radio channel, energy consumption,
operational costs, etc.




Main Topics:


The target of this workshop is to bring together academic and industrial
researchers to identify and discuss all  recent challenges and developments
related to cooperation in HetNets, and establish future research
directions.  Topics of interest
include but are not limited to the
following:

- Collaborative techniques in macro/pico/femto-cellular networks.
- Performance modeling and simulation for HetNets.
- Cooperative communications between HetNet nodes.
- Downlink and uplink PHY/MAC design for cooperative HetNets.
- Self-configuration, self-optimization and self-healing in HetNets.
- Cognitive radio techniques in HetNets.
- Mobility management in HetNets.
- Load balancing in HetNets.
- Restricted access versus open-access for low-power HetNet nodes.
- Interference analysis, mitigation and avoidance in HetNets.
- Power saving mechanism in HetNets.
- Distributed radio resource management in cooperative HetNets.
- Cooperative sensing techniques and feedback in HetNets.
- Remote radio headers planning and deployment.
- Expanded region picocells planning and deployment.
- Cooperative relaying in HetNets.
- eICIC techniques in
LTE-Advanced HetNets.
- MIMO techniques in HetNets.
- Positioning and tracking systems based on HetNets.




Instructions for Authors:
Submitted manuscripts must be formatted in standard IEEE camera-ready
format (double-column, 10-pt font) and must be submitted via EDAS (
http://edas.info/ ) as PDF files (formatted for 8.5x11-inch paper). The
manuscripts should be no longer than 5 pages. One additional page is
permitted if the authors are willing to pay an over-length charge at the
time of publication (manuscripts should not exceed 6 pages). Submitted
papers cannot have been previously published in or be under consideration
for publication in another journal or conference. The workshop Program
Committee reserves the right to not review papers that either exceed the
length specification or have been submitted or published elsewhere.
Submissions must include a
title, abstract, keywords, author(s) and
affiliation(s) with postal and e-mail address(es). A paper abstract must be
registered on EDAS by the deadline.
