METHOD FOR PROVIDING PEER TO PEER SOCIAL NETWORKING SERVICE (SNS) USING TRIANGLE RELATIONSHIP AMONG NODES

摘要

The present invention relates to a method for providing social networking service (SNS) to push and advertise data to one hop neighboring node using a node in a triangle relationship among nodes in an SNS system including a plurality of nodes. According to the present invention, the method for providing SNS comprises: a first step of generating data at a first node in the SNS system; a second step of pushing the data to a second node which is one hop neighboring node on-line when generating the data at the first node; a third step of sending a query message to one hop neighboring node on-line of itself at the third node when the third node which is one hop neighboring node which was off-line at the generation of the data at the first node; and a fourth step of pushing the data to the third node at one hop neighboring node on-line of the third node which received the query message.
