Our presentation for CFIC-2013. This paper describes a new model for local messaging based on the network proximity. We present a novelty mobile mashup which combines Wi-Fi proximity measurements with Cloud Messaging. Our mobile mashup combines passive monitoring for smart phones and cloud based messaging for mobile operational systems. Passive monitoring can determine the location of mobile subscribers (mobile phones, actually) without the active participation of mobile users. This paper describes how to combine the passive monitoring and notifications.

4. 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

5. 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

9. Cloud Messaging
• Cloud infrastructure
from vendor
• Google, Apple,
Microsoft, Nokia –
own cloud based
infrastructures for
notifications
• Google message: 4
Kb payload delivery

10. Google Cloud Messages

11. 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.

12. 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

13. 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)

14. Use cases
• Proximity marketing
• Deliver local area messages in retail
• Hyper-local new delivery in campuses.
