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 vicinity 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, microwave ovens, cordless phones, 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.
  • Topics: Some of the content may be dictated by the interests of the students. The following is a list of possible topics:

    Academic Integrity

    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 this class.
