A wide-area service discovery infrastructure provides a repository in which services over a wide area can register themselves and clients everywhere can inquire about them. In this paper, we discuss how to build such an infrastructure based on the peer-to-peer model. The proposed system, called Neuron, can be executed on top of a set of federated nodes across the global network and aggregate th...

It is a significant problem to provide a robust and portable software environment that can link together clusters of workstations and other heterogeneous computers. There are particular difficulties when the computer clusters to be managed transcend administrative boundaries across wide-area networks. We review some of the technologies that have emerged recently for managing arbitrary computer ...

This paper presents the detailed description of the Middleware for Application Interconnection in Personal Area Networks (MAIPAN), which is designed to ease distributed service development for mobile and nomadic environment. This middleware provides a uniform computing environment for distributed applications that operate in dynamically changing personal area networks (PANs). MAIPAN hides the p...
