[beasiswa] [info] Research positions - Ph.D. Students in Distributed Optical and Wireless Network Architectures - University of Dublin

University of Dublin, Trinity College Research positions - Ph.D. Students
and Postdoctoral Researchers Centre for Telecommunications Value-chain
Research (CTVR)

*Closing Date: Friday, 31st December, 2007*

The Centre for Telecommunications Value-chain Research (CTVR) invites
applications for Ph.D. students and post-doctoral researchers to work in the
Emerging Networks group, on distributed, optical and wireless network
architectures.

These research positions will be funded from a variety of sources and will
involve close collaboration with our industrial partners.

CTVR is a multi-disciplinary research institution incorporating many Irish
Universities together with a carefully chosen set of industrial partners to
work on those engineering and scientific challenges that will make the most
difference to the telecommunications networks of the future. The Emerging
Network group is based in the Trinity College University , in Dublin , and
focuses on the form of future networks in terms of protocols, control,
management, mobility handling, routing and other architectural issues.

*The research positions are available in the following areas:*

- Interdomain optical path provisioning, focusing on distributed
algorithms, protocols and network policies. Game theory seems a particularly
suitable approach to maximize operators' benefits in highly competitive
environment such as multi-domain networking.
- Multi-layer path provisioning. This research area aims at finding
optimal solutions to path provisioning and engineering at the electronic and
optical layers. Joint optimization of both layers is crucial for maximum
exploitation of network resources.
- Impairment-aware distributed algorithms for route and wavelength
selection in optical networks. Deployment of dynamically transparent
optical networks is currently limited by the low reconfiguration
capabilities of the optical transport layer. This research area aims at
minimizing or overcoming the signal impairments that phenomena like PMD,
path loss and chromatic dispersion generate on optical signals.
- Development of software-based routers, based on novel algorithms and
network protocols and on existing open-source routers (e.g., QUAGGA,
XORP, Click modular router).
- Ad-hoc optical networks. This novel research area aims at applying
ideas derived from wireless ad-hoc networks to the optical provisioning
domain, to enhance the reconfiguration capabilities of optical networks,
increasing resiliency and fault recovery. In addition, as data rates
constantly increase in access networks, an ad-hoc plug-and-play approach to
optical networking will facilitate the deployment of bandwidth at the
network edge.
- Identity management. This research area will focus on the issue of
how entities such as people, machines etc, will be identified in a future
Internet. Design issue will involve: form of identifiers, naming
authorities, security, etc.
- Efficient Video-Content delivery using Overlay Networks. In recent
years, new applications such as Youtube and on-demand TV (e.g., Jost)
have become the single major driver of traffic in the Internet. This project
will explore the trade-offs between centralized control and the ability to
harness user resources to solve the distribution problem in both an
enterprise and public Internet context.

Responsibilities for the positions include conducting research in the above
fields, contribute to the drafting and submitting of papers to top
international academic conference and journals, and contribute to the
overall activities of the research team.

Post-doctoral applicants are required to have a PhD in Applied Mathematics,
Electronic Engineering, Computer Science or a related field. PhD applicants
are required to have a M.Sc. degree on a relevant field.

Other requirements include good knowledge of communication networks, sound
analytical skills and programming skills (e.g. C/C++, Matlab), fluency in
English and effective written and verbal communication skills.

The compensation perceived will depend on the position covered and will be
commensurate with qualifications and experience to date.

*Closing date: 5pm on Friday 31st December, 07.*

Interested candidates may send a detailed CV, names of at least three
reference persons and a letter describing their research interests and goals
to:

Prof. Donal O'Mahony
Director,
Centre for Telecommunication Value-chain Research (CTVR)
University of Dublin , Trinity College ,
Dublin 2, Ireland .
