| Abstract | Mobile devices are currently one of the main sources of user-generated content. The portability and increasing capacity of these devices allow them to be used in various activities. This tendency has been accompanied by the progressive interest in sharing (in real time) the generated content. However, the common use of centralized services to support the sharing of data between users requires highly responsive services and places a high load on the network, reducing its bandwidth with data that (often) can be shared in the network edge. In this thesis we apply Thyme to real-world networks of Android devices, a data persistent publish/subscribe system for wireless networks of mobile devices, which provides a mechanism for data dissemination and storage adapted for this type of network, without requiring Internet access. In Thyme, time is a first order dimension, associating a time interval with each subscription, where the start and end of the interval may refer to the future, present, or past. As a use case we present an Android application for photo sharing. The experimental results show that developed work presents the desired behavior in an environment composed by a considerable number of devices, even managing to deal with mobility and churn. It was also possible to verify that Thyme presents response times that guarantee interactivity with the user, proved to be able to be used in events of short and medium duration, with a low energy consumption, allowing the application to be used without excessive battery costs . |
