New Mobile technologies have created a new social dimension where individuals can develop increased levels of their social awareness by keeping in touch with old friends, making new friends, dispense new data or product, and getting information in many more aspects of everyday lives, making one to become more knowledgeable which is very beneficial especially for students. Social networks, in pa...

According to CGI.br, the access to social networks is one of the main activities over the internet. With the popularity of mobile devices, the access to these platforms anywhere as well as the development of specific social networks for those devices become more and more common. To improve the engagement between the users and the so-called mobile social networks (RSM in Portuguese), gamificatio...

due to limitations in computing resources of mobile nodes, mobile ad-hoc networks (manets) are very fault-prone. so far, redundancy at different levels of the network has been considered an efficient strategy to enhance the fault-tolerance of networks. indeed, ad-hoc networks are extremely redundant; therefore, natural redundancy to fault tolerance enhancement has a great impact on the network ...

Recently observed social trends point to greater social approximation of individuals through technological platforms, as the increasing success of sites such as Orkut, MySpace, MSN, among others. The mobile social networks are also gaining adepts for having pervasives and customized features. In this demonstration, we show a concept of a mobile social network for students seeking study partners...

As and when the mobile users are increasing in day by day the demands of video traffic over mobile networks keep on rising, so the wireless link capacity cannot satisfying the demands of mobile user due to the variation in the link status and many disruptions, it causes long time buffering to mobile user. To overcome from this a framework is proposed for the efficient utilization of wireless li...

 In recent years, mobile networks have faced with the increase of traffic demand. By emerging mobile applications and cloud computing, Mobile Cloud Computing (MCC) has been introduced. In this research, we focus on the 4th and 5th generation of mobile networks. Data Centers (DCs) are connected to each other by high-speed links in order to minimize delay and energy consumption. By considering a ...

Mobile systems are characterized by several dynamic components like users’ mobility, devices’ interoperability and interactions among users and their devices. In this scenario context-awareness and the emerging concept of social-awareness become a fundamental requirement to develop optimized systems and applications. In this paper we focus on a novel category of pervasive and mobile systems des...

With the explosive proliferation of mobile devices, mobile crowdsourcing has become a new paradigm involving a crowd of mobile users to collectively take largescale tasks required by requesters in mobile social networks (MSNs). In this paper, we work on new task allocation schemes for mobile crowdsourcing in Opportunistic Mobile Social Networks (OMSNs) which are formed opportunistically when pe...

It is important for mobile service providers to be aware of user contexts and to provide contextually relevant mobile services to users. Thereby, in this paper, we propose a novel mechanism for integrating online social networks, which are regarded as an important channel for exchanging and propagating contexts. To efficiently discover personal contexts of certain users, the contexts of their n...

heretofore several position-based routing protocols have been developed for mobile ad hoc networks. many of these protocols assume that a location service is available which provides location information on the nodes in the network.our solutions decrease location update without loss of query success rate or throughput and even increase those.simulation results show that our methods are effectiv...
