About the Course
The number of 802.11 (Wi-Fi) chip sets shipped annually is now
over one billion units.
Competition among 802.11 devices operating in the same
combined with increasing network demands from applications
makes the maximization of network bandwidth and reduction
of latencies crucial to providing users
with good service.
Moreover, bluetooth equipped devices,
and other non Wi-Fi devices operating in the same
spectrum make it difficult for devices to
obtain peak performance.
In this course we will examine different techniques
for evaluating the performance of 802.11 networks
with a focus on a newly developed trace-driven framework.
We will also examine several different problems that
significantly impact the performance of Wi-Fi devices.
Possible topics are: rate adapatation algorithms, choosing
an access point to associate with, access point hand-off
and others that are of interest to the class.
Course Meetings : Most likely weekly discussion of 2-3 papers
but this format may vary.
Most meetings will involve reading and critiquing the
papers assigned as reading for that week.
Some of the content may be dictated by the interests of
the students. The following is a list of possible topics:
These are not strictly required but many of the papers and
discussion are likely to revolve around computer systems research
so a good background in the following areas are recommended.
- 802.11 networking (WiFi)
- operating systems
- systems programming skills
- good communication skills
- some performance analysis and statistics
Course Readings and Course Schedule
Course Project and Paper
Note that students are not generally permitted to submit the same
work for credit in multiple classes. For example, if a student
has reviewed or presented one of the papers in another seminar
class, he or she should avoid reviewing or presenting it again for
The general university policy:
- Academic Integrity: In order to maintain a culture of
academic integrity, members of the University of Waterloo
community are expected to promote honesty, trust, fairness,
respect and responsibility. [Check http://www.uwaterloo.ca/academicintegrity/
for more information.]
- Grievance: A student who believes that a decision
affecting some aspect of his/her university life has been unfair
or unreasonable may have grounds for initiating a grievance.
Read Policy 70, Student Petitions and Grievances, Section 4, http://www.adm.uwaterloo.ca/infosec/Policies/policy70.htm.
When in doubt please be certain to contact the department's
administrative assistant who will provide further
- Discipline: A student is expected to know what
constitutes academic integrity [check http://www.uwaterloo.ca/academicintegrity/]
to avoid committing an academic offence, and to take
responsibility for his/her actions. A student who is unsure
whether an action constitutes an offence, or who needs help in
learning how to avoid offences (e.g., plagiarism, cheating) or
about "rules" for group work/collaboration should seek guidance
from the course instructor, academic advisor, or the
undergraduate Associate Dean. For information on categories of
offences and types of penalties, students should refer to Policy
71, Student Discipline, http://www.adm.uwaterloo.ca/infosec/Policies/policy71.htm.
For typical penalties check Guidelines for the Assessment of
- Appeals: A decision made or penalty imposed under
Policy 70 (Student Petitions and Grievances) (other than a
petition) or Policy 71 (Student Discipline) may be appealed if
there is a ground. A student who believes he/she has a ground
for an appeal should refer to Policy 72 (Student Appeals) http://www.adm.uwaterloo.ca/infosec/Policies/policy72.htm.
Note for Students with Disabilities
The Office for Persons with Disabilities (OPD), located in
Needles Hall, Room 1132, collaborates with all academic departments
to arrange appropriate accommodations for students with disabilities
without compromising the academic integrity of the curriculum. If
you require academic accommodations to lessen the impact of your
disability, please register with the OPD at the beginning of each
