Our Study


Impact of physical social networks/relation on wireless
traffic


Study the Correlation between users’ activity/relation.


Identify the influence of social relation on web access pattern.


Relation
between users’ proximity and data
viewed


Impact of co
-
located peers on data
traffic


No existing study, to the best of our knowledge


Project duration: Hopefully a PhD thesis.


Why OCCS data?


CrawDad

&
MobiLib
.


Online traces:


Old : before 2008 (no smartphone activity).


Required Info. unavailable.


Why ODU wireless network


ODU campus size is identical (mid
-
size, semi
-
urban)


Flexible and controllable


wcsnet
: low usage and diversity.


Data Needed


Traces of wireless packets metadata (802.11 & 802.3
headers)


Device MAC prefix
: to classify smartphones.


Device MAC/ID (
anonymized
)


Associated Access Point ID
: used for co
-
location detection


Destination/Source IP/port
: accessed website and used
application.


Timestamp
: to order
and synch activities


Packet/Frame Size


Duration :
1

2 months
