Recently, mobile devices such as smartphones, wearables, and smart devices have overtaken PCs as the predominant platform for computing and communication. The shift to the mobile platform has brought with it a host of new challenges. Mobile devices have severely constrained energy capacity, their network connectivity is exclusively provided by unreliable bandwidth-constrained wireless links, and they carry a standard set of sensors that are seemingly insufficient for certain applications and also can inadvertently leak private information about their users.
In this course, we will discuss research that addresses the challenges introduced by the mobile platform by blurring the lines between traditional research areas in computer science.
As with many other research seminars, the course will be predominately a discussion of a set of research papers. However, we will also discuss the origins of these research projects, the impact that they had on the research community, and their impact on industry (spoiler alert: the impact on industry generally is much harder to predict than the impact on research). The course will also include a quarter-long project intended to be the seed of future publishable work.
This course will be mostly self contained. However, it will be useful to have some background in undergraduate networking (CSE 123) and operating systems (CSE 120). If you plan on working on a course project that involves embedded systems, you should either be a self-taught embedded systems hacker or have taken an embedded systems course (e.g., CSE 237A).
If you are taking the course for full credit (4 credits - letter grade), grading will be based on the following breakdown: Individual or group project (50%), paper notes and discussion lead (25%), and class participation (25%).
If you are taking the course for partial credit (2 credits - pass/fail), grading will be based on the following breakdown: paper notes and discussion lead (50%) and class participation (50%).
Your discussion notes should serve the following two purposes: as a quick reference guide for the paper and as an outline of the discussion that you will lead in class.
You should answer the following questions about the paper for the quick reference guide:
Your discussion-lead notes should consist of a list of the questions that you plan to use to seed the in class discussion.
