Analyzing the influence of mobile social communities on data dissemination in delay-tolerant networks

The study of data dissemination with social relationship in delay-tolerant networks can be significant from the perspective of technical novelty and performance. This paper adopts the time-variant community mobility model to formulate the relationship between user mobility and social community in delay-tolerant networks. With synthetic trace data of various user mobility and community patterns, simulation results show that the proposed model is able to interpret many characteristics of movement behavior and social community structure, accordingly, with a friendly graphic presentation. Therefore, the proposed analysis model can be applied to facilitate the design of social-based data dissemination mechanisms in delay-tolerant networks.
