    En aquellos hogares en los cuales las mascotas son consideradas parte de la familia, el extrav铆o de una mascota representa una situaci贸n angustiante tanto para el animal como para las personas. La prevenci贸n habitual consiste en colocarle una identificaci贸n a la mascota. Pero ocurrido el extrav铆o, de no haberse tomado dicha precauci贸n, el procedimiento habitual consiste en anunciar la b煤squeda en la v铆a p煤blica, junto a las caracter铆sticas de la mascota y en algunos casos una recompensa. Esta pr谩ctica se ha replicado en los 煤ltimos tiempos a las redes sociales. La diversidad de tecnolog铆as de posicionamiento, los c贸digos bidimensionales y los servicios de notificaci贸n pueden ser combinados para ofrecer, desde la tecnolog铆a, una soluci贸n a la problem谩tica. Las soluciones actuales son todas creadas ad-hoc. Esta es la principal motivaci贸n de esta tesis, donde se propone una soluci贸n de modelado para este tipo de problem谩tica. En esta tesina se describe un modelo de soluci贸n que promueve y busca acelerar la recuperaci贸n de mascotas al generarles, por ejemplo, un c贸digo QR que puede ser le铆do por cualquier persona que cuente con un smartphone con tecnolog铆a de posicionamiento (por ejemplo GPS) para, a trav茅s de una serie de alertas autom谩ticas, darle a conocer al due帽o la posici贸n de la mascota extraviada y facilitar el reencuentro con la misma. En base al modelo propuesto, se desarroll贸 un prototipo funcional con la funcionalidad mencionada.Facultad de Inform谩tic

    Cloud Services Brokerage for Mobile Ubiquitous Computing

    Recently, companies are adopting Mobile Cloud Computing (MCC) to efficiently deliver enterprise services to users (or consumers) on their personalized devices. MCC is the facilitation of mobile devices (e.g., smartphones, tablets, notebooks, and smart watches) to access virtualized services such as software applications, servers, storage, and network services over the Internet. With the advancement and diversity of the mobile landscape, there has been a growing trend in consumer attitude where a single user owns multiple mobile devices. This paradigm of supporting a single user or consumer to access multiple services from n-devices is referred to as the Ubiquitous Cloud Computing (UCC) or the Personal Cloud Computing. In the UCC era, consumers expect to have application and data consistency across their multiple devices and in real time. However, this expectation can be hindered by the intermittent loss of connectivity in wireless networks, user mobility, and peak load demands. Hence, this dissertation presents an architectural framework called, Cloud Services Brokerage for Mobile Ubiquitous Cloud Computing (CSB-UCC), which ensures soft real-time and reliable services consumption on multiple devices of users. The CSB-UCC acts as an application middleware broker that connects the n-devices of users to the multi-cloud services. The designed system determines the multi-cloud services based on the user's subscriptions and the n-devices are determined through device registration on the broker. The preliminary evaluations of the designed system shows that the following are achieved: 1) high scalability through the adoption of a distributed architecture of the brokerage service, 2) providing soft real-time application synchronization for consistent user experience through an enhanced mobile-to-cloud proximity-based access technique, 3) reliable error recovery from system failure through transactional services re-assignment to active nodes, and 4) transparent audit trail through access-level and context-centric provenance
