“…One representative example is vehicle navigation systems , which employ AOI to filter the useless spatial information and highlight the relevant ones. Another example is the social network applications for mobile systems [Safar et al 2009], which allow users to search for friends within the area they are in. We anticipate that the emerging applications of virtual and mixed reality environments, especially on new mobile devices, will further extend the use of the interest management techniques.…”

The past two decades have witnessed an explosion in the deployment of large-scale distributed simulations and distributed virtual environments in different domains, including military and academic simulation systems, social media, and commercial applications such as massively multiplayer online games. As these systems become larger, more data intensive, and more latency sensitive, the optimisation of the flow of data, a paradigm referred to as interest management, has become increasingly critical to address the scalability requirements and enable their successful deployment. Numerous interest management schemes have been proposed for different application scenarios. This article provides a comprehensive survey of the state of the art in the design of interest management algorithms and systems. The scope of the survey includes current and historical projects providing a taxonomy of the existing schemes and summarising their key features. Identifying the primary requirements of interest management, the article discusses the trade-offs involved in the design of existing approaches.

“…The result to the location query is a list of friends that roam in the same area. In (Safar et al 2008) the authors construct and analyze a network of friends using an existing account from a social network (i.e., www.hi5. com).…”

“…As discussed in Section 3.2, in order to protect user's location privacy, MILC combines different preferences for each user, real time notifications about location requests and the ability to disable a certain service. Work in (Safar et al 2008) proposes a location based Personal Digital Assistant (PDA) application which is implemented using two system modules in tandem. The first module is actually an application which enables users to send their birth year and get their horoscope in return.…”

MILC: A secure and privacy-preserving mobile instant locator with chatting

The key issue for any mobile application or service is the way it is delivered and experienced by users, who eventually may decide to keep it on their software portfolio or not. Without doubt, security and privacy have both a crucial role to play towards this goal. Very recently, Gartner has identified the top ten of consumer mobile applications that are expected to dominate the market in the near future. Among them one can earmark location-based services in number 2 and mobile instant messaging in number 9. This paper presents a novel application namely MILC that blends both features. That is, MILC offers users the ability to chat, interchange geographic co-ordinates and make Splashes in real-time. At present, several implementations provide these services separately or jointly, but none of them offers real security and preserves the privacy of the end-users at the same time. On the contrary, MILC provides an acceptable level of security by utilizing both asymmetric and symmetric cryptography, and most importantly, put the user in control of her own personal information and her private sphere. The analysis and our contribution are threefold starting from the theoretical background, continuing to the technical part, and providing an evaluation of the MILC system. We present and discuss several issues, including the different services that MILC supports, system architecture, protocols, security, privacy etc. Using a prototype implemented in Google's Android OS, we demonstrate that the proposed system is fast performing, secure, privacypreserving and potentially extensible.

“…Software systems should adapt to the users by anticipating their actions, communicating with other peers and entities which are in some way connected with the users and by taking into account the state of user's surroundings. This way of adaptation to the state and user's needs and preferences is called context-awareness and has been of a special interest to many researchers [1,24,41]. Therefore, context consisting of contextual information that describe a learner's profile is to enable personalised and adapted learning provision based on the learner's current location [41].…”

Therefore, context consisting of contextual information that describe a learner's profile is to enable personalised and adapted learning provision based on the learner's current location [41]. Context awareness is then being explored not just as a way to deliver appropriate content but to enable appropriate actions and activities, including interactions with other learners in the same or similar contexts [33].…”

Mobile collaborative learning is considered the next step of on-line collaborative learning by incorporating mobility as a key and breakthrough requirement. Indeed, the current wide spread of mobile devices and wireless technologies brings an enormous potential to e-learning, in terms of ubiquity, pervasiveness, personalization, flexibility, and so on. For this reason, Mobile Computer-Supported Collaborative Learning has recently grown from a minor research field to significant research projects covering a fairly variety of formal and specially informal learning settings, from schools and universities to workplaces, museums, cities and rural areas. Much of this research has shown how mobile technology can offer new opportunities for groups of learners to collaborate inside and beyond the traditional instructor-oriented educational paradigm. However, mobile technologies, when specifically applied to collaborative learning activities, are still in its infancy and many challenges arise. In addition, current research in this domain points to highly specialized study cases, uses, and experiences in specific educational settings and thus the issues addressed in the literature are found dispersed and disconnected from each other. To this end, this paper attempts to bridge relevant aspects of mobile technologies in support for collaborative learning and provides a tighter view by means of a multidimensional approach.
