The rapid development of OSNs provides opportunities for people’s daily communication, but also brings problems such as burst network traffic and overload of servers. Studying the population growth pattern in online social networks helps service providers to understand the people communication manners in OSNs and facilitate the management of network resources. In this paper, we propose a population growth model for OSNs based on the study of population distribution and growth in spatiotemporal scale-space. Methods We investigate the population growth in three data sets which are randomly sampled from the popular OSN web sites including Renren, Twitter and Gowalla. We find out that the number of population follows the power-law distribution over different geographic locations, and the population growth of a location fits a power function of time. An aggregated population growth model is conducted by integrating the population growth over geographic locations and time. Results We use the data sets to validate our population growth model. Extensive experiments also show that the proposed model fits the population growth of Facebook and Sina Weibo well. As an application, we use the model to predict the monthly population in three data sets. By comparing the predicted population with ground-truth values, the results show that our model can achieve a prediction accuracy between 86.14% and 99.89%. Conclusions With our proposed population growth model, people can estimate the population size of an online social network in a certain time period and it can also be used for population prediction for a future time."],["dc.description.sponsorship","Open-Access-Publikationsfonds 2013"],["dc.identifier.doi","10.1186/2194-3206-1-14"],["dc.identifier.gro","3149016"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/10428"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/5658"],["dc.language.iso","en"],["dc.notes.intern","Fu Crossref Import"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","final"],["dc.notes.submitter","chake"],["dc.relation.issn","2194-3206"],["dc.rights","Goescholar"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.title","Modeling population growth in online social networks"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

Many data routing strategies have been proposed for opportunistic MSNs. Most of them apply a utility for relay selection that a node with a higher utility value is selected as relay. However, such utility-based routing strategies run into dead end problem in which the data is stuck into a node with local maximal utility value. In this paper, we propose a virtual routing method named VIRO, which exerts conformal mapping to convert the local topology of dead end into a virtual geometric map to guarantee data dissemination to the next relay. We first convert the utility into geometric planner, and then conduct the discrete Ricci Flow bypass the gap between the dead end and next relay. Extensive experiment results suggest VIRO can reduce the ratio of dead end effectively so that the data delivery ratio is enhanced up to 42% by increasing only a slight amount of delay and cost."],["dc.identifier.doi","10.1109/ICC.2015.7248822"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/13260"],["dc.language.iso","en"],["dc.notes.preprint","yes"],["dc.notes.status","final"],["dc.publisher","IEEE"],["dc.relation.conference","IEEE International Conference on Communications"],["dc.relation.eventend","2015-06-12"],["dc.relation.eventlocation","London, UK"],["dc.relation.eventstart","2015-06-08"],["dc.relation.isbn","978-1-4673-6432-4"],["dc.relation.iserratumof","yes"],["dc.title","VIRO: A virtual routing method for eliminating dead end in Opportunistic Mobile Social Network"],["dc.type","conference_paper"],["dc.type.internalPublication","unknown"],["dspace.entity.type","Publication"]]

In this paper, we introduce the experiment methodology of deploying the Goose software in two campuses located in Germany and China respectively. Goose is a mobile social network application allows microblogging, message sending. With the help of volunteers, we collect user interaction data in the duration of 15 days. Based on the collected data, our observation reveals the following aspects of user interactions and their influences. First, user overall activities approximately match user daily life work pattern with a slightly longer time duration and periodically appearance. Second, user encounters in mobile social network follow the heavy tail distribution in small social communities, and user interactions follow the Pareto principle, where about 20% of users make close connections to the other users. Third, communication path between a pair of mobile nodes is mostly within 6 hops, and information diffusion using an epidemic strategy demonstrates that the informed population reaches to 50% in a short term and approaches to 80% in a long term."],["dc.identifier.doi","10.1145/1989656.1989659"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/14637"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.publisher","Association for Computing Machinery"],["dc.publisher.place","New York, NY, USA"],["dc.relation.conference","Social Network Systems"],["dc.relation.eventend","2011-04-13"],["dc.relation.eventlocation","Salzburg, Austria"],["dc.relation.eventstart","2011-04-10"],["dc.relation.isbn","978-1-4503-0728-4"],["dc.relation.ispartof","Proceedings of the 4th Workshop on Social Network Systems Art"],["dc.title","Exploring user social behaviors in mobile social applications"],["dc.type","conference_paper"],["dc.type.internalPublication","unknown"],["dspace.entity.type","Publication"]]
