The methods applied in our research focus on performance analysis of communication systems by
modeling,
mathematical analysis and
stochastic simulation.
These methods are applied to
Evaluation of existent or proposed communications protocols and their traffic performance comparison to each other
Design and optimization of services and protocols for digital communication networks, including
- formal specification of protocols (Specification and Description Language, SDL)
- implementation by a tool based translation into executable code to be used in both an existent simulation environment (SPEETCL) and on a target host (the tools are developed partly at the department)
- rapid prototyping of newly developed services and protocols to be experimented with in field trials
CASE tools development for software engineering based on formal specification methods including traffic performance analysis and optimization, spe...[202]...zation, including emulation of the destination hardware platform
Network architectures (Intelligent Networks, Universal Personal Telecommunications, etc.)
Scenario specific radio propagation (in-/outdoors) prediction based on raytracing
Development of radio channel models for indoors and outdoors
Use of smart antenna systems in mobile environments
Mobility models for road transport and mobile radio applications
Agent technology to improve existent services
Validation of the performance behavior of protocols by implementation and use in a real environment.
