2

A day in the life of a graduate student

why is a Ph.D. so painful???

was better without a Ph.D.

morning day night

3

So what have I been using all this time

mobile phones

social networks

sensors

GPSlaptops

embedded sensors

4

Other super cool applications!!

UMass TurtleNet

UMass Bus networkOpen Wi-Fi APs Volcano monitoring

Princeton ZebraNet

Underwater networks

5

Everything around qualifies as “Mobile/Pervasive Systems”

• “Pervasive” = “ubiquitous” = present everywhere• Embedded in your environment• Sensors, RFIDs, microcontrollers

• “Mobile” = anything that moves • A broad class of systems qualify as mobile systems• Laptops, cell phones, vehicular networks, wildlife

networks

• Applications are endless• Mobile phone applications, general purpose computing,

smart homes, health care, RFID-based localization, battery less computing

6

Why should I care?

• You use it everyday in almost everything you do • Can not more emphasize its practicality• Important to understand the challenges involved

• Very hot and open field---a lot is still to be done• Combination of networking, embedded systems, sensor

systems, location aware services, security• Right time to do a Ph.D. in it• Jobs still exist at Microsoft, Google, Nokia….

• Fun area to work in• Build apps for iPhones, Android, Windows mobile• Super cool sensor/pervasive systems for monitoring,

surveillance, day-to-day applications

7

Not convinced yet!

Millions of dollars invested by NSF, Darpa, Microsoft, and Google

~4 Billion cellular phones being used worldwide…

8

How is this field different from tethered computing?

wireless and mobile

wired and static

low channel loss rate traditional transport works predictable performance available connectivity

high channel loss rates traditional networking fails long period of outages fleeting connectivity

9

How is this field different from tethered computing?

AC-powered (infinite energy)

Battery-powered (infinite energy)

applications notpredicated on an energy constraint

almost everything tied to energy

10

Areas unique and will be covered in this course

will add to this list as time permits

wireless networking

Sensor systems

energy management

localization

mobile social systems

cloud computing

11

How will these topics be taught

• Lean how to program Windows Mobile 7

• Learn how to use the platform to understand localization, cloud computing, wireless networking

• Using microsoft resources• Microsoft SDK• Web services (Azure)• Hawaii toolkit

12

Advantages of using WM 7

• Very good support from Microsoft Research• Blogs, mailing list etc. I will

encourage you to

• Every group will work with real WM7 phones • High end phones with

accelerometer, compass, WiFi, GPS, and I will also provide 3G connectivity

• Hawaii competition• Best project will compete

with universities across the country for a cash award

13

How would the grading take place?

• Research paper reviews and discussion related to research topics (20%)

• In class problem solving (10%)• Interesting interview questions for software

companies like Microsoft, Google, CISCO

• Take home midterm (30%)• Mostly testing your analytical thinking and

understanding

• Mobile phone development project (40%)• Groups of at most two

14

I hate research papers but still got to read them…

• Important component of the course• Reviews are due before 12:00 a.m. of day of class• Submit reviews to nilanjan.banerjee@gmail.com• Subject: “CS5013: Paper review”

• Reading papers can become a boring activity • Follow advice from GA-6, GA-7

• My advice (follow it with a grain of salt )• *Do not* summarize the paper alone• Critically analyze the faults in the paper (no paper is

perfect!)• How can you use the paper in your research

15

Interaction: Class discussions

• Class will be composed of two components• Learning and applying Windows Mobile and Cloud

computing• Understanding current research in the area through

paper reading

• One course take home mid-term • You will have 24-hours to solve it• No collaboration allowed• Test your analytical thinking and course understanding

16

The coolest part: group research project

• Major chunk of the course is a research project (40%)• Groups of at most two• Goal is to have a WM phone demo by the end of the

course• No demo => no grades• Groups of at most 2

• Organize yourself• Every group will maintain a google site describing the

progress of the project• All brainstorming happens on the google site – I will

follow it closely• All source code and documentation will be distributed

through the google site

17

Example research project

3G/Wi-Fi

databasecloud services

sensors

Bluetooth

location service

sensor data + location + video?

inform doctors

18

Where is the computer science research here?

networking issues reliability data rate

machine learning services

Energy Management

Other ideas

come and talk to me during my office hours!

20

Lets get started with WM 7 development

• Getting the development environment working…

• Getting accustomed to C# and the Windows Mobile Emulator

• Start playing around with the platform.

• Resources• Hawaii :

http://research.microsoft.com/en-us/um/redmond/projects/hawaii/students/

• Free e-book: http://blogs.msdn.com/b/microsoft_press/archive/2010/10/28/free-ebook-programming-windows-phone-7-by-charles-petzold.aspx

21

Administrivia…

• Course webpage and reading list • http://www.csce.uark.edu/~nilanb/mobpervS.html• My email id: nilanb@uark.edu• Class hours: 11:30 – 12:20 M, Wed, Fri• Office hours: 3:00-5:00 Monday or by appointment

• Come and talk to me if you • Want stuff added/removed from the course• Ideas for new projects and applications• Phones would be distributed soon.

22

Next class

• Set up the WM development environment on your Vista or Windows 7 machine

• Teaching you how to use and write simple applications for the phone with the emulator

• Email me your groups for your projects before the beginning of next class and brainstorm on ideas and create a google site.
