“…They may be expressed in discrete values or a range of values. The reflective part of our architecture maps these high-level values on the low-level QoS of the system resources [14]. For each request, users may specify also input data (e.g., the document to print).…”

“…To achieve these goals it exploits reflection at the architectural level [3,8]. For more details related to the adaptivity feature and to the design of the reflective entities of our middleware, as well as to the definition and mapping of the requested qualities of services on the features of the physical components see [12,13,14]. In this paper attention is focused on the communications aspects, including the definition of services, of a protocol through which services are provided and required and of communication services among peers.…”

Today information systems provide services which may be accessed through various types of devices and/or networks and from different locations. Services should be adapted at runtime to the features of the requiring device. Moreover, users may specify additional information when claiming for services, information through which they indicate the quality level required and expected from the provided services. For example, users may request the printing of an image by specifying also the expected resolution, format and/or number of colors.In this context, we propose a mobile-enabled approach to design and implement adaptable services. Our solution defines three different service layers: (1) a low-level network communication layer providing connectivity services among the peers available in a system, (2) a middleware managing the system-specific services and defining a communication protocol for the services requests, and (3) a high-level application layer dealing with domainspecific services. In this paper, attention is focused on the middleware and network communication layers.
