Course Project Topics for CSE5469 Chunyi Peng Spring 2014

Topic List Mobile data charging (multiple choices) Security in cellular infrastructure Smart WiFi Offloading Mobile health app 802.11n/ac RA in mobile devices Spring 2014 CSE5469 (Peng)

#1 Examine Mobile Data Charging Project background Area: cellular, security 4G LTE/3G, or LTE+WiFi (heterogeneous network) Current practice: usage-based pricing Volume caps Argument/proposals: time-dependent pricing scheme (network congestion varies over time) (TUBE, Sigcomm’12 etc) Accounting may not be accurate (Mobicom’12 etc) Volume does not reflect value (app context, e.g., Ads in background traffic) Spring 2014 CSE5469 (Peng)

Possible Issues You can do either: Propose a new pricing scheme Rational & Design Evaluation via simulation and analysis Map of billing traps for Andriod Build a map and associated lookup service so that users can learn the potential billing traps in a given region. Note: strong background in database and programming is required Understand the true cost of various mobile apps Free and paid versions (ad volume?) Bursty traffic (web), long-term (video) and short long-lived (background) Hint: quantify the difference in network usage, app context (protocol overhead), signaling, physical resources etc Pricing for heterogeneous network (WiFi + Cellular) Spring 2014 CSE5469 (Peng)

#2: Security in Cellular (4G) infrastructure Project background Area: cellular, security LTE or LTE+WiFi (heterogeneous network) Motivation: LTE is an all-IP network (converges to the Internet), but still maintains many cellular (telecommunication) features such as control, gateway, network structures Example 1: unexpected mobile accounting (Mobicom’12, CCS’12, Mobisys’13, HotMobile’13, NDSS’14) Example 2: CSFB [tu13-csfb], Mobicom’13 Spring 2014 CSE5469 (Peng)

Possible Issues Survey on main security features provided in LTE Difference from the Internet Difference from the predecessors (3G/2G) Identify several or at least one major loopholes either in design (standard) or in practice Verification experiment Security analysis and remedy Note: It is an open research problem. Note: It involves a large amount of 3GPP standard reading. Spring 2014 CSE5469 (Peng)

#3: Smart WiFi offloading Project background Area: cellular, wireless, networking Heterogeneous network (WiFi + Cellular) Possible issues: Motivate fine-grained offloading by identifying the gain in opportunistic offloading (coarse rules can’t work well) LTE is faster and WiFi is crowded Coverage Determine offloading policy Propose the interface switch design Impact of app (IP address change) Prototyping or simulation for preliminary evaluation Spring 2014 CSE5469 (Peng)

#4 Mobile Health App Project backgroud Possible issues: Areas: Mobile, app Motivation: health and intimate use on the phone Possible issues: Utilize sensors and mobile app contexts for health monitoring Build a simple mobile-cloud paradigm Adaptation on mobile vs cloud. Exploit participatory sensing (crowdsourcing) if possible Security and privacy features (optional) Spring 2014 CSE5469 (Peng)

#5. 802.11* Rate Adaptation in mobile devices Project background Areas: wireless, mobile 802.11n/ac mainly: MIMO (multiple antennas) 802.11* standard family provides many rate options Modulation and coding scheme #Antenna #Streams Rate adaptation (RA) = the method to select the transmission rate in real time Linuxwireless: open source http://wireless.kernel.org/ -Design One direction: flexible or mobile-specific RA for Hybrid performance goals: throughput, energy efficiency, optimization for specific applications (video, navigation, gaming etc) Spring 2014 CSE5469 (Peng)

Possible Issues Identify performance difference in mobile vs. desktop Hardware (chipset, antenna) Software (limited interfaces) Design new RA algorithms for smartphone Hint: Hybrid performance goals, mobile-specific Possible evaluation (optional) Extend RA to mobile-adaptive 802.11 E.g., WiFi scanning and WiFi offloading, WiFi -Design One direction: flexible or mobile-specific RA for Hybrid performance goals: throughput, energy efficiency, optimization for specific applications (video, navigation, gaming etc) Spring 2014 CSE5469 (Peng)

Other options Define your own project In OS, programming, AI, data mining New mobile apps Work on key techniques (energy efficiency, sensing, CHI, security, privacy) But likely competitive due to a large amount of related work Spring 2014 CSE5469 (Peng)
