For a project on communication network optimization in Chemnitz, Germany, we have one open (PhD candidate or Post-Doc) full-time position. Employment will be at the Chair for Communication Networks at TU Chemnitz. The position will become available for a period of one year starting from 1st October 2013 at the earliest. Further continuation is possible.

Research Field:

The research project VINO (VIrtual Network Optimization) addresses two problem statements related to communication network planning and optimization: - Optimum configuration and dynamic adaptation of Flexgrid optical transport networks (Flexgrid Optical Network Design (FOND) problem) - Embedding and dynamic adaptation of virtual networks within a physical network infrastructure (Virtual Network Embedding (VNE) problem)

Responsibilities:

The following research tasks should be performed by the candidate in the project: - Design and evaluation of online algorithms to handle incoming resource requests (i.e. optical connections in case of FOND and virtual network requests in case of VNE) in real time (online optimization problem) - Re-optimization of the network configuration while the network is in service

Requirements:

- MSc or equivalent degree in Mathematics or Information Technology / Computer Science - Background in at least one of the following areas: - discrete optimization (especially mixed-integer linear programming) - online optimization - communication network architectures and protocols - Experience with solvers for linear optimization problems (e.g. CPLEX) - Programming skills (e.g. C/C++) - Good English language skills

Applicants should submit their documents (including a letter of interest, CV, copies of academic certificates and previous scientific work such as master or diploma thesis) preferentially via Email to:
