Ubiquitous Social Sensor Networking system

Social Networking Sites (SNS) require a centralized system accessible via Internet. SNS´ owners are in control of user´s data; this often leads to data theft, piracy and privacy issues. This paper proposes a way of socializing with people in surrounding places by using a ubiquitous social sensor network system (USSNS) where Wireless Sensor Node interact in a peer-to-peer mode without the need of Internet. Sensor Node are programed in order to exchange selected social information (e.g. status availability, emergency) to their peer sensor node within a predefine network coverage area (~ 10 indoor to 100 meter outdoor) via a multicast request. The result of this system could allow node´s user to find their peer via nodes´ LED lightening and engage in a face-to-face conversation if they are willing to. The USSNS aims to promote face-to-face interaction instead of current virtual interaction on SNS. The system was tested on two K-mote B2 devices using CoAP protocol.
