In the recent years the Internet evolution has undergone a remarkable and unstoppable change of trend, rooted on three main pillars, new
technologies (cloud computing, SDN, NFV, etc.), broad connectivity (3G/4G, VANET, etc.), and the wide deployment of smart edge
devices (smart phones, sensors, wearables, etc.), all setting the main concept for the Internet of Things (IoT), also encompassing
scenarios such as smart cities, ITS (Intelligent Transport Systems) or e-health. The main IoT objective, also becoming its main
characteristic, focuses on the development of new services, with a high societal impact, leveraging the huge deployment of smart devices
embedding reasonable data procesing capacities. Indeed, the capacity to produce and collect data (big/open data) along with IoT
concepts, enables and fosters the development of the envisioned new services, but also imposes strong network and performance
constraints, such as low latency and high security, all necessary to run the demanded features inherent to these services, such as
dependeability in e-health or real time in traffic control in ITS
The fog computing concept recently came up aiming at nearing the cloud capacities to the edge, what definitely paves the way to meet the required network and performance constraints, reducing network load, reducing latency and easing security guarantees.
Its development is the rationale for its success since it boils down to adding traditional cloud capacities (viz. storage, network and
processing) to elements either existing or not (e.g., traffic lights and streetlights in smart cities or cars and trains in ITS), hence setting the
possibility to generate multiple fog levels, vertically scaling up till reaching out to the cloud. However, fog does not exclude cloud, rather it
complements and optimizes cloud performance, so as those services that cannot be implemented in the lower fog level (lack of processing
or storage capacities), will keep demanding higher fog levels or cloud, and those services requiring specific fog skills (low latency, security)
may run close to the edge device. Thus, a hierarchical vertical and horizontal cloud structure is set, from the edge device to the traditional
cloud level. This hierarchical architecture is requiring efforts to design a novel management strategy responsible for orchestrating the set of
services to be (in a distributed and parallel way) implemented at different fog/cloud levels. Moreover, crucial issues in fog computing, such
as volatility, dynamicity, security, mobility, connectivity, new business models, energy efficiency, etc., must also play a key role in the
definition of such management strategy.
The GUAU Project proposes the design of a management strategy for a hierarchical cloud architecture that encompasses different fog and
cloud levels, all vertically and transversally coordinated, supporting main foundations (e.g. security, privacy, mobility and energy efficiency)
for optimizing services deployment in IoT scenarios. The Project will focus on three smart scenarios, namely e-health, ITS and smart cities,
assuming the deployment of fog capacities on these scenarios and its utilization to ease the deployment and execution of the desired
