Contents

The lecture describes and analyzes the basic functions of protocols and explains the most important algorithms and methods, which are used in communication systems. The exercises complement the lecture by applying the theoretic knowledge to special problems.

The lecture usually includes an excursion to a working telecommunication network. The lecture is intended for Master students in electrical engineering, possibly also for students in computer science and mathematics.

Topics

  • Concepts and definitions of digital communication networks
  • Data transmission from point-to-point
  • Synchronization aspects
  • Multi-access protocols
  • ALOHA protocols (slotted, unslotted) and collision resolving strategies
  • Carrier-Sensing (with and without collision detection)
  • Techniques for reliable data transmission (ARQ- and hybrid-ARQ techniques)
  • Routing algorithms, flow in graphs, shortest path routing
  • Markov-chains
  • Queuing theory
  • Lossless and lossy queuing systems
  • possibly: Network Coding
  • Project orientated lab: ARQ, Markov chains, simulation of queuing systems
