Student-Project Overview

Mobile users or stations in an ad-hoc network may see at a certain point in time several other stations to which they can potentially communicate. This perceived neighborhood depends, e.g., on the communication range of the station's radio transmitter but also one pattern by which the mobile user moves around.

If a mobile station follows its trajectory, another station might move in the same direction and thus the perceived neighborhood between the two is uphold — they can continue communicating with each other. On the other hand, the perceived neighborhood relation between two nodes discontinues if they move in different directions and thus out off their communication vincinity.

This project shall evaluate how different mobility models influence the perceived neighborhood of a mobile station.

The basis will be an existing 802.11 -based simulation model which has been enhanced by protocol features currently under development in the IEEE standardization process.

• Experience in C/C++ programming

The students are required to

• get aquainted with the exinsting simulator (OPNET Modeler) and the existing mobility models
• decide in accordance with their supervisor on the number and kind of mobility models to evaluate
• enhance the simulator's mobility model library with missing models
• explore the properties of the choosen mobility models
• conduct a simulation-based evaluation of the influence of the mobility models on the perceived neighborhood.
