Nowadays, an increasingly connected ecosystem of heterogeneous devices is continuously producing unbounded streams of data that have to be processed “on the fly” in order to detect operational exceptions, deliver real-time alerts, and trigger automated actions. This paradigm extends to a wide spectrum of applications with high socio-economic impact, like systems for healthcare, emergency management, surveillance, intelligent transportation and many others.

High-volume data streams can be efficiently analysed in real-time through the adoption of novel high-performance solutions targeting today’s commodity parallel hardware. This comprises multicore-based platforms including mobile devices, heterogeneous systems equipped with GPU and FPGA co-processors, and large-scale distributed-memory systems like multi-Cloud and Fog computing environments. However, despite the large computing power offered by the affordable hardware available nowadays, high-performance data streaming solutions need to be equipped with smart logics in order to adapt the framework/application configuration to rapidly changing execution conditions and workloads. Moreover, the burst in the amount of data streams generated at the network edge by sensors and devices and the emergence of applications with predictable and low latency requirements require a shift from the traditional data stream processing performed in a central data center to a geo-distributed processing environment as represented by Fog computing and multi-Clouds. Such a new and challenging scenario demands for mechanisms and strategies for adapting the data stream computation to changes in the operating environment and workload and for dealing with uncertainty, fostering novel interdisciplinary approaches.

The special issue aims at collecting high-quality scientific contributions from the research community working in the fields of data stream processing, data analytics algorithms, big data frameworks and autonomic resource management. The main focus is on parallel and autonomic models and practical implementations on parallel heterogeneous hardware and distributed systems.

We solicit papers covering various topics of interests that include, but are not limited to the following:
* Autonomic resource management for data streaming processing in geo-distributed infrastructures, including resource deployment and provisioning and admission control
* Adaptive load balancing policies for streaming computations
* Queries and data streaming operator placements on Fog resources
* Real-time analytics architecture for IoT
* Elastic techniques and runtime reconfiguration strategies for bursty workloads and varying resource demands
* Programming models and toolkits for supporting Fog Computing for data streaming
* Smart sensors and in-network processing in the context of Fog Computing
* Parallel algorithms and runtime solutions for data streaming
* Decentralized data stream mining algorithms and systems
* Case studies of Fog-based real-time analytics in various domains (Healthcare, IoT, Smart Cities, Social Networks)
* QoS for real-time analytics for Fog Computing and IoT services

All submitted papers will be peer-reviewed by at least three reviewers and selected on the basis of both their quality and their relevance to the theme of this special issue.
