On blockchain and its integration with IoT. Challenges and opportunities

This research came from the need for a client application where researchers want to store and share their large-sized research data among their community. This application necessitates data exchange while respecting the media content owner’s privacy and sharing rights. To develop this client decentralized application, each issue related to storage, propagation capacity, or access permissions needs to be addressed along with the network structure and execution flow to work as swiftly as possible. To mitigate these challenges, we introduce the TBAAC (Token-based attributed access control) management, a modified attribute-based access control (ABAC) scheme to explore the full potential of the used schemas and strategies in a blockchain-supported client application. The presented tokenbased attributed access control has been validated through regress simulations and specified use cases of the DWS client application.

Composite Web Services (CWS) aggregate multiple Web Services in one logical unit to accomplish a complex task (e.g. business process). This aggregation is achieved by defining a workflow that orchestrates the underlying Web Services in a manner consistent with the desired functionality. Since CWS can aggregate atomic and other CWS they foster the development of service layers and reuse of already existing functionality. An important issue in the deployment of services is their run-time performance under various loads. Due to the complex interactions of the underlying services, a CWS they can exhibit problematic and often difficult to predict behaviours in overload situations. This paper focuses on the use of request scheduling for improving CWS performance in overload situations. Different scheduling policies are investigated in regards to their effectiveness in helping with bulk arrivals.

Transparent Scheduling of Composite Web Services

By defining workflows, existing services are put into novel contexts and exposed to different workloads, which in turn can result in unexpected behaviors. This paper examines the chaotic behavior of sequential workflows in overload situations and discusses the use of call-contexts as a means of avoiding them.

Using Call-Context to Prevent the Emergence of Chaotic Workflow Behaviors in Overload Situations

Web Services (WS) are one of the most popular approaches for building distributed systems due to their widespread acceptance within industry and academia, established and open standards, a wealth of development tools/infrastructures (e.g. Apache Axis [1]), and maybe most importantly the number of successful deployments. A key issue in the deployment of WS is the elasticity of services e.g. their ability to respond to changes in the demand by dynamically adding or removing WS provider nodes. This paper presents a novel P2P based management approach for WS providers, that allows organizations to dynamically add or remove replicated providers at runtime and thus increases their elasticity. Unlike the current centralized approaches, this scalable P2P approach allows for a fully distributed and fault-tolerant management of replicated provider and thus enables organizations to respond faster to changes in WS consumer behavior.

Improving the Elasticity of Services with a P2P Infrastructure

The half-day tutorial demonstrates how web-assembly techniques can be used to create sandboxed user models as digital twins within web- and mobile applications. Such models can learn from the user’s behaviour and personalise the application to the user, while ensuring transparency of the model, and ability for the user to experiment and control the personalization. The advantage of using webassembly techniques to implement digital twin user models is that the user model is a plugin, insulated from the application, and thus the protecting the privacy of the user model.
