• A new model for local area messaging based on the network proximity. • Mobile mashup which combines Wi-Fi proximity measurements with Cloud Messaging. • Passive monitoring can determine the location of mobile subscribers (mobile phones) without the active participation of mobile users.• Cloud Messaging delivers notifications

Introduction
Passive Wi-Fi monitoring
Cloud Messaging
Local area messaging mashup
Conclusion
Passive Wi-Fi monitoring
• Wi-Fi probe request• Client (even not
connected) can send requests to AP
• AP can analyze requests
• We can collect MAC-addresses for clients
Advantages and disadvantages
• Does not require special mobile applications • For mobile users it works automatically and transparently• It is anonymous monitoring. MAC address is used for re-identification only. It could be replaced with some hash-code (privacy)• It is not 100% reliable. There is no warranty that Wi-Fi client will send probe request

Cloud Messaging
• Cloud infrastructure from vendor
• Google, Apple, Microsoft, Nokia – own cloud based infrastructures for notifications
• Google message: 4 Kb payload delivery
Google Cloud Messages
Key moments for Cloud Messaging
• Application register with Cloud Messaging• Application provides a key from Cloud
Messaging server (subscribes) to the particular application (Sender)
• Sender saves keys and use them later for delivering notifications
• Key moment – subscription is activated from the mobile application on the particular phone.
Key moments for mashup
• Let us extend the subscription process
• Mobile application (mobile phone, actually) will provide a key for notification and MAC-address for identification
• Sender can compare saved MAC-addresses with the MAC-addresses, collected by the passive monitoring
Key moments for mashup - 2
• Sender can deliver notifications to those, who are nearby only.
• It is real-time detection
• MAC-address is used for the re-identification only. So, it could be replaced with some hash-code (privacy)
Use cases
• Proximity marketing
• Deliver local area messages in retail
• Hyper-local new delivery in campuses. Tested in Lomonosov Moscow State University
• Smart Cities information delivery
