Social wireless and mobile networks have received more attentions over the recent years. Previously, we proposed the Social Relation Opportunistic Routing (SROR) algorithm for mobile social networks, and introduced the social relations and profiles among nodes as the key metrics to compute the optimal forwarding node in routing such that the packet delivery probability is maximized. In this paper,...
Virtual teams play an increasingly important role in the modern economy, and many organizations struggle to overcome the weaknesses inherent in technology-mediated work. Identity communication has been shown to greatly improve individual- and group-level outcomes in offline settings, but these benefits have not been investigated in the context of virtual teams, where mediated interaction can reduce...
E-commerce has fundamentally changed during the past few years through the ability to track customers' activities, map their social networks and use social influence, approach them proactively, provide customized offerings and manage individual lifecycles. Moving from managing the community to managing its individual members within the community is the common denominator in many related developments...
In the recent years, social applications have competed to incorporate emerging technologies and innovative aspects like semantics technologies, location based services, data ephemerality to ensure user privacy, etc. Although few applications combine these aspects, our challenge is to gather them in applications for communities. Likewise due to the limited resources of mobile devices and the growing...
The ever-accelerating growth of cloud-based services (CBS) and the prevalence of multi-sided business models have distributed users' data across different data silos that hinder mobile applications development and sustainability. The present paper aims at describing an open framework that abstracts functionality from CBSs through a common Graph, RESTful API, which manages calls among various CBS APIs...
The growing awareness that human communications and social interactions are assuming a stratified structure, due to the availability of multiple techno-communication channels, including online social networks, mobile phone calls, short messages (SMS) and e-mails, has recently led to the study of multidimensional networks. In this context we perform the first study of the multiplex mobile social network,...
In mobile social networks, users can communicate with each other over different telecom operators. Thus, for telecom operators, how to attract new customers is a significant issue. The work of churn prediction is to determine whether a customer would leave soon. Differing from churn prediction, our work is to find those users who are likely to join target services from the competitors in the near...
We present a new service discovery algorithm, termed SIDEMAN, which considers human mobility for service dissemination and discovery. SIDEMAN takes advantage of mobile social networking characteristics, such as user membership to a restricted number of communities and interest for similar services among users in the same community. We evaluated the performance of SIDEMAN via simulations in a scenario...
Mobile karaoke has attracted more attention as a popular mobile entertainment and social network platform, where music recommendations are highly desired to improve its user experiences. Traditional music recommendation methods suffer from the data sparsity issue and usually ignore the social interactions among users. In this paper, we propose a novel parallel community-based matrix factorization...
Mobile social networks have emerged as a new frontier in the mobile computing research society, and the commonly used social structure (i.e., community) has been exploited to facilitate the design of network protocols and applications, such as data forwarding and worm containment. However, community based approaches may not be accurate when applied for predicting node contacts and may separate two...
Seventy percent of the population in Myanmar lives in rural areas. Although health workers are adequately trained, they are overburdened due to understaffing and insufficient supplies. Literature confirms that information and communication technologies can extend the reach of healthcare. In this paper, we present an SMS-based social network that aims to help health workers to interact with other medical...
The emerging of mobile social networks opens opportunities for viral marketing. However, before fully utilizing mobile social networks as a platform for viral marketing, many challenges have to be addressed. In this paper, we address the problem of identifying a small number of individuals through whom the information can be diffused to the network as soon as possible, referred to as the diffusion...
In this paper, we study two tightly coupled issues: space-crossing community detection and its influence on data forwarding in Mobile Social Networks (MSNs) by taking the hybrid underlying networks with infrastructure support into consideration. The hybrid underlying network is composed of large numbers of mobile users and a small portion of Access Points (APs). Because APs can facilitate the communication...
The research on the efforts of combining human and machine intelligence has a long history. With the development of mobile sensing and mobile Internet techniques, a new sensing paradigm called Mobile Crowd Sensing (MCS), which leverages the power of citizens for large-scale sensing has become popular in recent years. As an evolution of participatory sensing, MCS has two unique features: (1) it involves...
The aim of pervasive system technology is to support the user in managing and interacting with devices in the environment around him/her. By contrast social networking systems are aimed at supporting communication and interactions between people. The major objective of the SOCIETIES project is to unite these two technologies in a seamless manner to create a platform that enables the user to interact...
In this paper, we propose a novel approach for the analysis of large-scale mobile telecommunications social networks. To search for alpha users that are essential for social marketing, we propose using both graph theory and linear algebra. In particular, we first look for all trusses in a social graph based on graph theory and then find out alpha users in the trusses based on linear algebra. While...
In order to provide the mobile multimedia service cost-effectively, the smartphone user's demand on free access to widely deployed Wireless LAN (WLAN) systems has been greatly increasing. This is because 3G or 4G mobile networks are usually expensive, and slower than WLAN. Unfortunately, although secure WLANs are installed widely, they are usually not shared. In this article, we have designed and...
Sensor-equipped mobile devices have allowed users to participate in various social networking services while they are on the go. We focus on proximity-based mobile social networking environments where users share information obtained from different places via their mobile devices when they are in proximity. Since people are more likely to share information if they can benefit from the sharing or if...
Most of the governments and civil society organizations work hardly to promote the disabled people especially blind and deaf persons to join the normal community and practice the regular daily life activities. Indeed, Information Technology with its modern methodologies such as mobile and Cloud computing has an impressive role in enhancing the inter-communication among the people with different disabilities...
The increasing popularity of social networks improves information sharing among different users. Most existing online social networks involve the client/server architecture where each user needs to access to a server for contents sharing with other users. In this paper, we focus on constructing a mobile peer-to-peer based social network. We propose an efficient mobile social network to facilitate...
