Framework para construção de aplicações adaptativas em nuvem multimídia

Abstract

Currently traditional desktop computers and laptops are losing market share to more pervasive devices such as smartphones, tablets and wearables that usually have hardware limitations due to restrictions on size, weight, and battery life. The most popular applications today involve multimedia and sometimes consume more resources than these devices are capable of supporting, for example, augmented reality, games, and the use of computing to extend the cognitive ability as facial and speech recognition, natural language processing, machine learning, planning and decision making. In this context, even the widespread cloud computing does not serve as a single-handed solution, since the latency and jitter create a restriction for interactive applications. This work proposes a framework for building adaptive multimedia applications, which, on the client side, allows for exploring resources from reachable devices, whether mobile or not, in order to make applications more immersive. Not only quantitative, but also qualitative resources are considered to distribute tasks. Regarding the cloud side, the proposal appropriates the idea of edge cloud computing to increase Quality of Service (QoS) and allow business rules to be also taken into account during the distribution of tasks and service tuning.
