Implementing and using Grids requires a suitable Grid middleware. A reference model for the architecture of Grid middleware is the Open Grid Service Architecture (OGSA) which proposes a service-oriented architecture based on Web service technologies. As a consequence, the potential of such OGSA compliant Grid middleware is limited by the capabilities of Web service technologies. Recently, multi...

The GridTrust Security Framework (GSF) offers security and trust management for the next generation Grids (NGG). It follows a vertical approach for Grid security from requirements level right down to application and middleware levels. New access control models for collaborative computing, such as the usage control model (UCON), are implemented for securing the Grid systems. The GSF is composed ...

A positioning middleware benefits the development of location aware applications. Traditionally, positioning middleware provides position transparency in the sense that it hides low-level details. However, many applications require access to specific details of the usually hidden positioning process. To address this problem this paper proposes a positioning middleware named PerPos that is trans...

Ubiquitous computing is a challenge for the design of middleware. The reasons are resource constraints, mobility, heterogeneity, etc., just to name a few. We argue that such middleware has to be tailored to the application scenario as well as to the target platform. Such tailormade middleware has to be built from minimal fine-grained components, and the system structure must be highly configura...

Middleware is an integral part of all modern control systems [1]. In the past the term middleware was used to refer to the first abstraction layer between the lower-level hardware access layer and the higher level application layer. It was often introduced to hide the network communication protocols. Middleware has developed far beyond this. Modern control systems can now have multiple middlewa...

This paper makes two contributions to the study of configuring real-time aspects into quality of service (QoS)-enabled component middleware and distributed real-time and embedded (DRE) systems. First, it compares and contrasts the process of integrating real-time aspects into DRE systems using conventional QoS-enabled distributed object computing (DOC) middleware versus QoS-enabled component mi...

This paper presents Arcademis, a Java-based framework for communication middleware development. Arcademis consists of a set of abstract classes, interfaces and concrete components that define the general architecture of middleware systems. Its main objective is to support the implementation of non-monolithic and easily configurable middleware platforms. Arcademis can be used by middleware devel...

Recently, the intelligent services demands interactions with the sensor networks, actuator networks, and context aware applications. Actuator network supports an infrastructure to have an immediate access to information for controlling the physical world and its objects using sensor networks and context aware applications. Actuator network middleware supports the command message transfer for co...

In the RFID middleware the traffic load are increase and it is depend on the number of unmanaged RFID tag that cannot be handle by the RFID middleware. Because of that, there are possibilities that the data cannot be process efficient in RFID middleware. Implementation of agent technology is useful in the verification for RFID system architecture because intelligent agent has a role such as aut...

In this paper, we examine two architectural alternatives— native OS support versus middleware—for supporting multimedia applications. Specifically, we examine whether extensions to OS functionality are necessary for supporting multimedia applications, or whether much of these benefits can be accrued by implementing resource management mechanisms in a middleware system. To answer these questions...
