In this paper, we propose a new paradigm for local communication between devices in Ubiquitous Computing environments, assuming a multitude of computerized everyday appliances communicating with each other to solve tasks. This paradigm is based on the concept that the location of devices is central for the communication in such a scenario. Devices define their communication scope by spatial cri...

One of the challenges in designing distributed, embedded systems is the paucity of formal, executable specification notations that provide support for both real-time and asynchronous communication. This paper describes a timed architecture design language (Timed Architecture Interaction Diagrams or TAID) that, by virtue of its formal, executable semantics, combines the benefits of synchronous s...

This paper describes a number of optimizations that can be used to support the eecient execution of irregular problems on distributed memory parallel machines. These primitives (1) coordinate inter-processor data movement, (2) manage the storage of, and access to, copies of oo-processor data, (3) minimize interprocessor communication requirements and (4) support a shared name space. We present ...

We describe an architecture called WebFINDIT that allows dynamic couplings of Web accessible databases based on their content and interest. We propose an implementation using WWW, Java, JDBC, and CORBA’s ORBs that communicate via the CORBA’s IIOP protocol. The combination of these technologies offers a compelling middleware infrastructure to implement wide-area enterprise applications. In addit...

In this paper, we investigate the need for well-suited remote communication architectures to address communication issues in mobile agent environments. We study the implication of mobility for agent architectures – specifically, ways in which the architecture may facilitate agent communication. We present an architecture for inter-agent communication suitable for remote messaging, agent monitor...
