  1. Mitigating the True Cost of Advertisement- Supported“Free” Mobile Applications Presentation by: Scott Corey Report by: A. Khan, V. Subbaraju, A. Misra, S. Seshan

  2. “Free” Applications Consumers have grown accustomed to “free” applications supported by advertisements Free versions of Angry Birds earns $1 million+ a month in advertisements

  3. Data Traffic • Consumers data usage is growing exponentially • Many major providers now have metered data plans • Most devices have alternative connections that are free • Wi-Fi • Femtocell

  4. CAMEO Context-Driven Advertisement Modulator and Optimizer The current “free” application model is unsustainable Inexpensive and unmetered bandwidth is readily available Advertisements can be prefetched during these opportune times The advertisement served is context-dependent

  5. Characterization of Mobile Advertising Traffic Began with experiment using “free” apps on a Nexus One Applications were tested with 15 minutes of runtime (30 minutes for “Friends” games) Network traffic was recorded to identify and compare usage from advertisements or the application itself

  6. Results Non-negligible amount of traffic from each application Usage varied based on quantity of advertisements

  7. Math • Fruit Ninja – 5.61 Kbps on average • Played for 30 minutes per day • On Verizon Wireless • Current data plan: $30 for 2GB per month • The advertisements alone generate ~40MB of traffic, roughly 56 cents of data • Paid version is 99 cents

  8. Trending Upwards Advertisements are getting larger, more interactive HTML5 based ads are typically 5-20 times larger Multiple applications can be running at one time “Free” applications are not free!

  9. Key Characteristics of Mobile Advertising Combination of users profile and recent environmental context

  10. Context • Network phone is connected to • Ads for other carriers • Location • Ads for city events • Applications used • Ads for similar applications and same developers • Model of the phone • Ads for newer phones

  11. Mechanics of Advertisement Delivery • Advertisements were overlaid overtop applications • Most applications used multiple advertisement networks • Multiple connections were necessary • Contact network • Get XHTML or Javascript code • Fetch actual advertisement

  12. Back to CAMEO Must predict likely future context of the user/device Intelligently utilizing available alternative networks Serving advertisements from a local cache

  13. Compatible with existing deployments • Must reduce cost of current advertising methods • Interception • Switch to CAMEO from connecting to outside networks • Advertisement Generation • Must have cached appropriate advertisements in advance • Combination of cache manager, ad-prefetcher, and context predictor • Cannot distinguish advertising traffic • Cannot verify if correct advertisements were provided

  14. Clean-Slate Design • Application Modifications • Can query CAMEO components directly • Applications verify advertisements are received and appropriate • Infrastructure Modifications • Data prefetching can be done in a network-friendly fashon • Networks can provide additional information to enhance context • Opens up advanced possibilities of advertising
