Highly dynamic distributed applications often require flexible coordination among several autonomous components. Space-based middleware provides a suitable, data-driven coordination paradigm for such scenarios, where distributed peers exchange data and commands in a scalable and decoupled way using shared tuple spaces. In its basic form, such a middleware supports access to a data storage and (blocking)...
Distributed applications require coordination of distributed software components in order to achieve a common goal. A coordination model that abstracts the complexity of network communication eases the development of such applications. The objective is to design collaboration with remote hosts in the same way as local interactions. Separation of coordination logic and application code increases maintainability,...
The deployment of cooperative ITS applications is due to start as soon as 2015. Large investments in the roadside unit (RSU) infrastructure will be necessary to create a dense network and accommodate an increasing number of services, leading to a discussion about the trade-off between distributed processing and storage solutions on the RSU nodes and the centralized alternative. A strictly central...
Coordination in distributed embedded systems requires complex synchronization of many concurrent activities. This task becomes especially difficult when network and system failures have to be assumed. The Peer Model is a novel programming model for the design of coordination strategies among multiple nodes, aiming to bridge design and implementation. A major advantage is that designs based on the...
One of the ideas of agile software development is to respond to changes rather than following a plan. Constantly changing businesses result in changing requirements, to be handled in the development process. Therefore, it is essential that the underlying software architecture is capable of managing agile business processes. However, criticism on agile software development states that it lacks paying...
For constantly changing businesses, it is essential that the underlying software architecture is capable of managing agile business processes and meeting future business needs. Decoupling between applications and services in distributed systems is addressed by e. g., service-oriented architectures. On the other hand, applications and its underlying middleware are still tightly coupled with respect...
