Evolution of computer networks

Today’s scenario
• Users are rather mobile• Always connected and
producing content• Devices are very powerful
(CPU, storage, comm. tech., sensing)• Information is exchanged
based on interest• Users present
patterns in social behavior
Waldir Moreira, [email protected] http://copelabs.ulusofona.pt
Relation with Social Psychology discipline
• Opportunistic networking• Takes advantages of
sporadic contacts
• Social awareness• Abstracted from times users spend together• Different social angles• Common affiliation, node importance,
community, shared interests, levels of social interactions
• Social-aware networking is less volatileWaldir Moreira, [email protected] http://copelabs.ulusofona.pt
Relation with Social Psychology discipline
• The issue: definition of social (No consensus)• Social strength = different levels of contacts• Social interaction = mere contact/encounter• Social connection = how long the devices of users
are within the communication range of one another• Dynamic social behavior = how often devices meet• Social similarity = shared interests,
common communities, node popularity• Friendship = frequency/regularity of encounters

The SONID effort
• Sociality-aware Opportunistic Networking for Information Dissemination
• Exploit the Relational Models Theory (RMT) • Communal sharing (CS), individuals are equivalent
and resources shared freely; • Authority ranking (AR), individuals are ordered in
linear hierarchies of authority and respect; • Equality matching (EM), individuals reciprocate in
order to balance out inequalities; • Market pricing (MP), individuals seek best
cost-benefit relational solutions.Waldir Moreira, [email protected] http://copelabs.ulusofona.pt
The SONID effort
• Understand the variability between an individual's different social relations and respective evolution within them.
• Infer it from how the users handle their personal mobile devices.
• Consider the surroundings of the user and, more specifically, with whom the user socially engages.
• To drive the decisions regarding the exchange of information.
