General comments

• Labs (using OPNET simulator)
• A number of labs will be performed by the
  students to reinforce the fundamentals
• A lab assignment will be performed to introduce
  the student into a WLAN planning and design
  exercise.

12
General comments (cont)

• Paper presentation
• Every student will present 1 paper (or share a
  paper) over the semester period. Selection of
  topic by end of 2nd week.

13
General comments (cont)

• Research Projects
• Selection of a research topic. A list is provided
  on the web site. By end of 2nd week select topic.
• Each student will present their project
  objectives and work plan during the 4th week of
  the course. The student will by then have
  identified at least a core paper, which will be
  used as the basis for the research project.
• Each student will present the review of at least
  one paper which is core to the chosen research
  project (6th week) and link to their project
  work.
• Brief outline of progress (10th week).
• Final presentation of research project (focus on
  results) 13th week of the semester.

  throughout the course.

15
Sample list of Research Topics

• General topics of interest
• WLAN
• UMTS
• RRMs
• Ad-hoc networks
• Sensor networks
• Autonomic mobile networks

16
Sample list of Research Topics (cont.)

• 3rd Generation and beyond Mobile Networks
• ( a ) Performance Evaluation using simulation
  tools (OPNET),
• (b) resource allocation issues for UMTS
• (c) Radio Resource Management mechanisms (One or
  more from Power control, handover, admission
  control, load control, packet scheduling)
• Research of modifications and additions to mobile
  network RRM mechanisms (power control, handover,
  admission control) to enable the use of different
  communication modes (unicast, multicast,
  broadcast)

17
Sample list of Research Topics (cont.)

• WLAN resource allocation issues (RRM in WLAN)
• IEEE802.11e (service prioritisation, investigate
  video streaming and compare with IEEE
  802.11a/b/g)
• Wireless sensor network test bed (can be a
  project of a team of 2)

18
Sample list of Research Topics (cont.)

• VoIP System evaluation in mobile networks.
  Evaluation of signalling protocols for session
  establishment. Influence of transport protocols
  (TCP, UDP, SCTP) on their performance
• Analysis and modelling of UMTS traffic. Traffic
  characteristics in modern networks have radically
  changed compared to past years. Recent studies
  have shown that packet arrivals are not
  exponentially distributed. Instead, such arrivals
  have been modelled as self similar processes
