Generic middleware can often not provide satisfactory solutions, but neither is it acceptable to let the application developer reinvent the wheel each time. Therefore, middleware shall support reuse of infrastructural services while leaving the application in control. In particular, we contribute with a middleware approach to support adaptive dependability by balancing integrity and availabilit...

This paper presents the Real-Time Event Detection Service using Data Service Middleware (DSWare). DSWare provides data-centric and group-based services for sensor networks. The real-time event service handles unreliability of individual sensor reports, correlation among different sensor observations, and inherent real-time characteristics of events. The event service supports confidence functio...

The goal of the Globe project is to design and build a middleware platform that facilitates the development of large-scale distributed applications, such as those found on the Internet. To demonstrate the feasibility of our design and to test our ideas, we are currently building a new Internet application: The Globe Distribution Network. The Globe Distribution Network, or GDN, is an application...

Service-oriented technologies have simplified the development of large, complex software systems that span administrative boundaries. Developers have been enabled to build applications as compositions of services through middleware that hides much of the underlying complexity. The resulting applications inhabit complex, multi-tier operating environments that pose many challenges to their reliab...

Internet has evolved into an indispensable service delivery infrastructure. Various application services such as multimedia services and web services have been widely deployed and used. However, due to the problems pertaining to scalability, reliability, and manageability, traditional monolithic service provision approach has become inadequate. Thus, we propose a compositional approach for prov...

Peer-to-peer computing is a remarkable tool that has emerged in recent years, most notably in the form of music sharing services, but in a variety of other interesting guises as well. Just as the design of web browsers has required many generations to reach a certain level of usefulness and usability, service designs for peer-to-peer computing environments present numerous unresolved technical ...

This paper aims at demonstrating the benefits and importance of the service concept in the model-driven design of distributed applications. A service defines the observable behaviour of a system without constraining the system’s internal structure. We argue that by specifying application-level interaction aspects as a service, and designing application parts in terms of this service, the design...

Abstract In order to develop a distributed storage system that adapts Chinese software and hardware, build cloud computing platform is independently usable, safe reliable, data utilization more concentrated intelligent, service integration unified efficient. This paper designed implemented supports which compatible with mainstream CPU, operating system, database, middleware other hardware envir...

The number of computing devices, mostly smartphones is tremendous. potential for distributed on them no less huge. But developing applications such networks challenging especially as most middleware solutions are tailored to managed grids and clusters, so they lacks the elasticity needed deal with difficult conditions brought by multi-hops, mobility, heterogeneity, untrustability, etc. To solve...
