A Ranking Information Forwarding Algorithm with Social Characteristic in Mobile Delay Tolerant Network

With the gradual expansion scale of mobile intelligent terminals and the popularity of social networks, information exchange among mobile users shows the social characteristics. This article takes the same interest information among users to define the social relationship metrics such as contact frequency, contact strength and contact regularity etc. A ranking information forwarding algorithm with social characteristic in mobile Delay Tolerant network is presented and the simulation results show that this algorithm performs better in delivery rate, lower delay and buffer memory.
