Current Internet of Things (IoT) development requires service distribution over Wireless Sensor and Actor Networks (WSAN) to deal with the drastic increasing of network management complexity. Because of the specific constraints of WSAN, centralized approaches are strongly limited. Multi-hop communication used by WSAN introduces transmission latency, packet errors, router congestion and security...

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 increasing diffusion of mobile computing and of portable devices with wireless connectivity identifies new challenging scenarios for service provisioning. The access from devices with limited heterogeneous capabilities to traditional and novel Internet services requires new infrastructures capable of integrating with the fixed network and of supporting service tailoring/adaptation. The pape...

Middleware has become an integral part of many distributed applications offering effective integration and interoperability solutions. In some situations a problem may occur where the integration of distributed information applications may be affected by scheduled unavailability of one or more of these applications. The scheduled unavailability occurs due to several reasons including applicatio...

In the sensing as a service paradigm, Internet of Things (IoT) Middleware platforms allow data consumers to retrieve the data they want without knowing the underlying technical details of IoT resources (i.e. sensors and data processing components). However, configuring an IoT middleware platform and retrieving data is a significant challenge for data consumers as it requires both technical know...

To support integration of clinical and research data, the makers of REDCap, a widely-used electronic data capture system, released the Dynamic Data Pull (DDP) module. Although DDP is a standard module in REDCap, institutions must develop custom middleware web services to exchange data between REDCap and local source systems. The lack of middleware is a barrier to institutional adoption and use ...

1. INTRODUCTION In recent years, middleware has emerged as an important architectural element in modern computer systems. For the purposes of this paper, we define middleware to be a layer of software residing on every machine and sitting between the underlying (heterogeneous) operating system platforms and distributed applications/ services, offering a platform-independent programming model to...
