Abstract: Wireless mesh networks (WMNs) and wireless sensor networks (WSNs) are two emerging wireless technologies which will have important impact in the future. For example, wireless mesh networking is an enabling technology to provide wireless access in rural areas. This course will cover the fundamental design principles behind building scalable WMNs and WSNs. The following aspects will be covered: PHY layer technologies, medium access control, routing protocol design, transport layer issues, capacity issues and application. It will also cover case studies on deploying wireless mesh and sensor networks.
This course includes a laboratory component and minor design project.

This course is an advanced research-oriented course designed for graduate students with computer networks background. Through this course, students can learn the state of art of wireless ad hoc networks research, and enhance their potential to do research in this exciting area.
 

 

 

 

 

 
 

 

 

 
Synopsis:
  • Half-Course, Praktische Informatik, Hauptstudium.
  • 2 lectures per week, 2h each, over one semester (4SWS VL).
  • 1 lab (Praktikum) per week, 2h each, over one semester (2SWS PR).

Credits and grading:

  • There will be a few, short, unannounced, closed-book quizzes to verify your existence and to test your understanding.
  • To qualify for the final written examination (at the end of the semester), you have to complete all lab assignments to the satisfaction of the teaching assistant (70% = 35 points).
  • Regular class attendance is expected; frequent absences are grounds for a failing grade regardless of other performance. You may be missing up to 1 lecture per semester without prior and reasonable excuse. 'prior' means notification by email before the end of business the day before the lecture. 'reasonable' means sickness or study-related events that require your attendance.
  • Lectures begin on time. Students arriving more than 10 minutes late will not be admitted to the lecture and will be counted as 'missing' that day.

Prerequisites:

  • Computer networks background.
Syllabus - Lecture:

Part I – Theory and Basics

  • Transmission Fundamentals [pdf, ppt],

  • Antenna and Propagation [pdf, ppt],

  • Signal Encoding [pdf, ppt] / Spread Spectrum [pdf, ppt],

  • Coding and Error Control [pdf, ppt],

  • Orthogonal Frequency Division Multiplex (OFDM) [pdf, ppt],

Part II - Practical Application

Part III - Advanced Topics

Syllabus - Lab (Praktikum)

Im Praktikum befassen wir uns mit den gängigen Werkzeugen zum Entwurf und Evolution von Wireless Mesh Networks. Die Aufgaben sind für Gruppen zu 2 Personen ausgelegt. Das Praktikum ist in 2 Teile gegliedert: Der erste Teil besteht aus 3 eng umrissenen Aufgaben, in denen Sie sich mit einigen Werkzeugen und Protokollen vertraut machen sollen. Anschließend sollen Sie ihre Kenntnisse in einem von Ihnen gewählten Bereich in Form einer Projektarbeit vertiefen.

Um Ihnen wertvolle Arbeitszeit zu ersparen, haben wir bereits eine virtuelle Maschine eingerichtet, die Sie hierher beziehen können (Alternativ auch hier zu finden, solange der FTP-Server nicht verfügbar ist). Zum Ausführen können Sie den VMware Player benutzen. (Hinweis: Bitte aktualisieren Sie die installierten Software-Pakete nicht, da Sie sonst Gefahr laufen, die virtuelle Maschine zu zerstören.)
