We proposed MobiTribe which enables device centric social networking on smart mobile devices while reducing high communication costs and battery usage normally associated with mobile distributed systems. In this paper, we demonstrate the feasibility of MobiTribe by integrating the service with the popular social networking application Facebook. We show that(More)
We focus on dissemination of content for delay tolerant applications, (i.e. content sharing, advertisement propagation, etc.) where users are geographically clustered into communities. We propose a novel architecture that addresses the issues of lack of trust, delivery latency, loss of user control, and privacy-aware distributed mobile social networking by(More)
An increasing portion of traffic in mobile networks comes from users creating content and uploading it to the Internet to share it. The capacity of mobile networks is a limited resource and uploading high resolution content consumes a large part of it. We introduce MobiTribe, a distributed storage cloud consisting of mobile devices for storing the content(More)
Distributed social networking services show promise to solve data ownership and privacy problems associated with centralized approaches. Smartphones could be used for hosting and sharing users data in a distributed manner, if the associated high communication costs and battery usage issues of the distributed systems could be mitigated. We propose a novel(More)

Mobile devices are ubiquitous, and mobile-generated traffic is arguably a major component of today's web traffic. In particular, the use of smart-phones whilst commuting using public transport is a very popular and common practice in many countries. Mobile commuters however, often suffer from poor performance due to limited bandwidth and/or intermittent(More)
Crowd-Cache is a novel crowd-sourced content caching system which provides cheap and convenient content access for mobile users. Our system exploits both transient colocation of devices and the spatial temporal correlation of content popularity, where users in a particular location and at specific times would be likely interested in similar content. We(More)
Mobile video traffic is exploding and it is particularly challenging to stream video when high density of users are "on the move", e.g., in public transport systems. It becomes increasingly problematic as video traffic is predicted to account for more than 80% of Internet traffic by 2019. This will be exacerbated by factors such as cellular network coverage(More)
Yalut is a novel user-centric hybrid content sharing overlay for social networking. Yalut enables the users to retain control over their own data and preserve their privacy, whilst still using the popular centralized services. In this demonstration, we show the feasibility of Yalut by integrating the service with the popular social networking apps on(More)
