Encouraging Cooperation Through Community Dynamics

187

Published on

Cooperation among users only takes place if they are willing to share data among themselves. As users tend to easily exchange information with others they have some sort of social relationship (i.e., belong to the same community, share similar interests), we discuss how information about users’ relationships and communities they belong to can be used to increase social capital and, consequently, improve cooperation within the sensing context.

This presentation was given as a teaser topic in the 6th Approaches to Paradigms of a Future Internet (API): Cooperative Sensing as a Valuable Social Media, on Jan 26th, 2012, at Cisco Systems, Porto Salvo, Portugal.

  1. 1. Encouraging Cooperation Through Community Dynamics Waldir Moreira, Davidson Junior, Filipe Vieira,Ronedo Ferreira, Eduardo Cerqueira, Christian Rothenberg waldir.junior@ulusofona.pt Jan 26th, 2012 API 6th Think-Tank Meeting Cisco Systems, Porto Salvo, Portugal
  2. 2. Agenda• Scenario today• Encouraging cooperation• Role of communities• Open issues 2
  3. 3. Scenario today• Miniaturization → Portability → Popularization 3
  4. 4. Scenario today• Powerful devices • Higher processing capabilities • Greater storage space • Full of sensors • Accelerometer, Noise (microphone), Movement (camera), Proximity, Ambient light, Presence (WiFi, Bluetooth interfaces) 4
  5. 5. Scenario today• Sensors everywhere 5
  6. 6. Encouraging cooperation• Social information is rather useful for data exchange• Users tend to cooperate with other familiar users • Relationships, interests, popular individuals• Formation of different communities • Mitigating the egoistic effect • Increasing social capital • Encouraging cooperation 6
  7. 7. Role of communities• Social information can group users together • Sensory data, news, public interest broadcast, etc• Explicit and implicit use of community notion• Social metrics • Contact among nodes, their relationships, common interests, and popularity within society• Community dynamics • Determine strong relationships (increase social capital) • Identify truly interested parties in the information • Instigate cooperative behavior 7
  8. 8. Open issues• How to suitably capture community structure changes? • Relationships, interests change over time• Single use of social metrics • Their combination? How to combine? Thresholds? • Humans are all unique individuals 8
  9. 9. AcknowledgmentsTo all my colleagues at ITEC (UFPA) and CPqD for their contributions to this teaser And FCT, for my PhD grant (SFRH/BD/62761/2009) 9
