University students are tech-savvy and heavy users of both mobile phones and online social networks. Facebook is particularly popular and research has addressed many different questions regarding use of this specific online social network. In this Horizon paper we look into how university students use online social networks from mobile devices, a topic that has yet to receive significant attent...

Complex communication networks, more particular Mobile Ad Hoc Networks (MANET) and Pocket Switched Networks (PSN), rely on short range radio and device mobility to transfer data across the network. These kind of mobile networks contain duality in nature: they are radio networks at the same time also human networks, and hence knowledge from social networks can be also applicable here. In this pa...

This paper presents a novel framework for ubiquitous social networks (USNs). Instead of making virtual connections, on the basis of human social networks, an effort has been made to facilitate interactions among human social networks with the help of virtual social networks. The imperative domains that support ubiquitous social networks are highlighted and different scenarios are provided to pr...

In this paper we focus on the application of reinforcement learning to obstacle avoidance in dynamic Environments in wireless sensor networks. A distributed algorithm based on reinforcement learning is developed for sensor networks to guide mobile robot through the dynamic obstacles. The sensor network models the danger of the area under coverage as obstacles, and has the property of adoption o...

Abstract First-generation mobile TV has involved delivering content to cell phones. But as mobile TV evolves, it will find greater significance as part of a multifaceted video offering that combines multiple screens, devices, networks, and content types. Content, or a particular viewing session, moves with the user, across devices and across networks. Furthermore, in addition to providing an al...

Along with the popularity of mobile social networks (MSNs) is the increasing danger of privacy breaches due to user location exposures. In this work, we take an initial step towards quantifying location privacy leakage from MSNs by matching the users’ shared locations with their real mobility traces. We conduct a three-week real-world experiment with 30 participants and discover that both direc...

This paper presents a brief overview of findings collected from an ethnographic field study of young people and their use of mobile telephones. The findings indicate that mobile phones provide young people with a means of demonstrating their social networks. That is, through owning and using mobile phones, young people demonstrate their participation in social groupings and define the boundarie...

Recently, mobile applications have offered users the option to share their location information with friends. Using data from a major location-based social networking application in China (a Foursquare-like application), we estimate a structural model of restaurant discovery and observational learning. The unique feature of repeated customer visits in the data allows us to examine observational...

In this paper, we consider the problem of efficient social media access on mobile devices, and propose an Offline Online Social Media (OSM) Middleware to: (i) rank the social media streams based the probability that a given user views a given content item, and (ii) invest the limited resources (network, energy, and storage) on prefetching only those social media streams that are most likely to ...
