Subject aims

Designing different types of wireless networks. Optimization of multi-channel multi-interface wireless networks. Analysis and performance optimization of the various medium access techniques and routing metrics (within different protocols) from the point of view of flow, delay, jitter, overhead and energy efficiency. Mastering procedures and tools for modeling, simulation and optimization of modern radio networks.

Subject outcome

Student will become familiar with working principles of different types of modern wireless networks. Student will be able to propose changes to the MAC layer and define routing algorithms for the purpose of improving the performance of the entire system. After passing the final exam,the student should know how to choose a suitable optimization method, model the appropriate subsystem of the radio network, perform simulation procedures, optimize the subsystem of the radio network, and make conclusions based on the obtained simulation results.

Subject contents

Theoretical teaching
