KSE631: Content Networking Uichin Lee KAIST KSE March 5, 2013

Content? Definition of “Content” – 5. intellectually interesting material: material or ideas that are considered to be interesting, challenging, or worthwhile (Encarta 2009) Wikipedia: – Content is information and experiences that may provide value for an end-user/audience in specific contexts

Examples of Content Traditional content – TV programs – Movies – News articles – Books User created content (Web 2.0)? – News – Blogs – Lifelogging – Social networking (Twitter, Facebook, etc) – Wikipedia – Smartphone sensing

Content Delivery/Dissemination Content may be delivered via any medium such as the Internet, television, and audio CDs, as well as live events such as conferences and stage performances (Wikipedia)

Content Networking Beyond simple content delivery (e.g., TV), users now share their content with (and interact, collaborate with) other users via Web 2.0 services (e.g., Wikipedia, Blogs, Youtube, Twitter, Foursquare) Always-on connectivity (e.g., in Smartphones) greatly promoted this phenomenon Content networking also emphasizes “interactivity” and “integration” – Interactivity among users RSS feeds, user comments/tags, social networking – Integration of content in different sources

Content Networking Vision: seamless integration of content (e.g., data, information, knowledge) in multiple domains (including user/sensor generated content) to derive new values for end-users in ways that the author of content didn't plan or imagine Content networking: – Generate or gather, and represent complex and cross- disciplinary content from various sources and (possibly) at enormously large scales – Collaborate in groups and organizations, sharing this content and working together interactively across space, time, disciplines, and scientific cultures to create new values

Content Networking: Big Picture Internet Smart home/office On the move Applications Content provider Fixed access Content Networking Radio access

Content Networking Human: Wisdom of crowds, crowdsourcing, human computation Mobile device: Sensing (camera, GPS), ubiquitous computing Network: Internet, mobile networks (w/ advanced services) Application: Agent, processing, mining Internet Smart home/office On the move Applications Content provider Fixed access Content Networking Radio access Device Network Application Human Crowd

Ubiquitous (Social) Computing

Devices in all form factors Sensors everywhere Rich user interactions (input/output) Always connected (wirelessly) Networked people (being social) Computation, communication, and sensing are integrated into the physical world

Sensor Everywhere Mobile Health Intelligent Transportation Smartphone Sensing

Rich User Interactions

Social Networking

Always Connected Always-on connectivity (3G/4G/LTE) Short-range wireless for consumers – Bluetooth, WiFi (802.11a/b/g/n) Body Area Networks – Transmit data thru the body

Caveats This course is not focused on “computer networking” – You don’t need to know all the details, yet you need to know the “basics” to design and implement efficient “systems” Recall: content networking is to gather and represent content, and collaborate with others, by sharing the content and working together interactively

Why Learning Android Programming? Good platform for testing applications Java based programming (easy to learn) Market demands Emphasis on networking + device intelligence Job markets

Lecture Notes/Books Computer Networking: A Top Down Approach – Will cover Chapter 1 (intro), 2 (app layer), 3 (TCP), 4(IP), 6(Wireless), 8 (security) Android programming – Hello, Android (3 rd ed), Ed Burnette – Professional Android 4 Application Development, Rete Meier Research/survey papers

Paper Critique Paper Critique Writing Guidelines – Provide a brief summary of the article in your own words (also state the main concept and key contributions) – State the strength/weakness of the paper – Post any questions that you have 14 lectures have paper critique assignments – Submit 10 critiques (you can skip 4 papers) – A lecture may have multiple papers (in this case, I’ll tell you want to read) Submit your critique via Ideascale – Due on 1PM Tuesday/Thursday (no late submission)

Use Your Real Name so that I can know it’s YOU
