Master or Diploma Thesis: Traffic Emulation in a Multi-RAT Testbed

Title:
Traffic Emulation in a Multi-RAT Testbed

Description:
In order to evaluate and analyze power management mechanisms and algorithms in modern wireless networks (see ComGreen for more information), the Telekom Innovation Laboratories operate a Multi-RAT Testbed in Berlin, Germany. This testbed comprises state of the art technologies, such as WiFi and WiMAX and is planned to be extended in order to support 3GPP access technologies in the future.

Being connected to the Multi-RAT testbed, users cause a lot of events in the network, e.g., handovers between different access points or sending HTTP requests to hosts in the network or Internet. To track and analyse these events in a real network with a high number of clients, real users must move around the Multi-RAT testbed while actively using it. As this would require substantial effort, one needs to think of other approaches. A possibility to solve this problem is to deploy a user emulator, a software based system representing real users in the network.

The main objective of this thesis is to design and implement a traffic emulation service that enables the operator of a Multi-RAT testbed to emulate devices in the network that produce certain traffic while moving through the network. The implementation is required to be transparent, so that it is not determinable whether the traffic is produced by a real connected client or by an emulated client.

Challenges:

• Develop a model and an architecture for user emulation
• Implement defined modules
• Perform tests for user emulation with different patterns
• Analyze additional signalling traffic in the network caused by the new emulator system

Prerequisites:

• Interest in Wireless Networks and Testbeds
• Proficiency in programming
