The Future Internet has emerged as a new initiative to pave a novel infrastructure linked to objects (things) of the real world to meet the changing global needs of business and society. It offers internet users a standardized, secure, efficient and trustable environment, which allows open and distributed access to global networks, services and information.
To be consistently adopted, the Future Internet will be enabled through standards-based notations for messaging, semantics, process and state (such as those RDF, OWL, SOAP, REST and WS-BPEL), enabling distributed systems and entities to be described in a scalable and flexible robust dynamic environment. Multi-tenancy will enable their remote access as Software as a Service (SaaS), by performing the integration into larger networks of communicating software (e.g., a mashup or a plug-in to a Cloud platform). Future Internet applications will have to support the interoperability between many diverse stakeholders by governing the convergence and life-cycle of Internet of Contents (IoC), Services (IoS), Things (IoT), and Networks (IoN). These applications should handle dynamic and continuous change: for example, in the provisioning of services, availability of things and contents, connectivity of networks, diversity of user devices etc. They should also bear in mind that the Future Internet should provide a better experience for the user journey, with personalized and context-aware contents, adapted to their preferences, and where users also play an active part in creating or sharing services.
There is a need for both researchers and practitioners to develop platforms made up of adaptive Future Internet applications. In this sense, the emergence and consolidation of Service-Oriented Architectures (SOA), Cloud Computing and Wireless Sensor Networks (WSN) give benefits, such as flexibility, scalability, security, interoperability, and adaptability, for building these applications. Although there already are emerging solutions to host software services and data on remote computers and create public sensor networks by using these technologies; the mentioned solutions employ simple technical approaches related to replication strategies to ensure availability and to achieve a load-balancing scalability. Future Internet systems however, will also need to sense and respond to a huge amount of signals sourced from different entities in real-time. In this context, an event would be detected if, for example, there is non-existence of a signal which normally occurs, affecting the execution of other services. These events would be produced by IoT and processed in the IoS. In order to build business level events Complex Event Processing (CEP) may be used. CEP allows detecting complex and meaningful events and inferring valuable knowledge for end users. The main advantage of using CEP to process complex events is that the latter can be identified and reported in real time, reducing the latency in decision making, unlike the methods used in traditional software for event analysis. Event-Driven Service-Oriented Architectures (ED-SOA or SOA 2.0) are also being used to respond to events that occur as a result of business processes.
The first edition of WAS4FI was held in conjunction with ServiceWave 2011, in Poznan, Poland, on October 28th 2011. Extended versions of accepted papers were published as invited chapter in the book Adaptive Web Services for Modular and Reusable Web Service Development, published by IGI Global. We had around 18 participants in the workshop venue.
The second edition was held in conjunction with ESOCC 2012, in Bertinoro, Italy, on September 19th 2012. In this occasion, the 2nd International Workshop on Adaptive Services for the Future Internet and the 6th International Workshop on Web APIs and Service Mashups joint. Papers were published in ACM Digital Library, ICPS available in this link. We had around 24 participants in the workshop venue.
The third edition was held in conjunction with ESOCC 2013, in Málaga, Spain, on September 11th 2013. Papers were published by Springer CCIS, available in this link. We had around 25 participants in the workshop venue. In addition, a public call for papers open to all potential authors worldwide, and also including extended submissions of selected papers of the third edition of WAS4FI, a Special Issue of the Journal of Universal Computer Science (JUCS) on Adaptive Services for the Future Internet is under publication.
In this fourth edition, WAS4FI again aims to bring together the community at ESOCC and addresses different aspects of adaptive Future Internet applications, emphasizing the importance of governing the convergence of contents, services, things and networks in order to achieve building platforms for efficiency, scalability, security and flexible adaptation.
In this workshop, we cover the foundations of the aforementioned technologies as well as new emerging proposals for their potential in Future Internet services. To promote collaboration, WAS4FI has a highly interactive format with short technical sessions complemented by discussions on Adaptive Services in the Future Internet Applications.
