Mobile Social Networks (MSNs) have become one

of the emerging wireless communication techniques due to

ubiquitous mobile devices, such as smartphones and pads,

and their inherent proximity-based sharing capability, such as

WiFi and Bluetooth. MSNs are originally developed to enable

mobile users to opportunistically exchange information via

social contacts even without permanent network connectivity

between users. To cope with nonpersistent connectivity in a MSNs, previous

studies proposed routing protocols to enhance the probability that

data would be delivered to the destinations. 

In this talk, we focus on two content disssemination issues in MSNs. This first one is 

the dissemination of advertising and multimedia

content; i.e., service providers might not know who would be interested

in the content objects (messages); therefore, they tend to

propagate the messages to every user in MSNs. 

The second one is that we discuss, in MSNs, how to opportunistically share

multimedia content among users based on their personal preferences.
