Advances in the areas of pervasive environments, computing, and networking are leading to an infrastructure composed of a large number of heterogeneous services/devices. Although some network protocols accommodate heterogeneity of services and/or devices, existing protocols have various design goals and solutions. This paper outlines a Ubiquitous Web Services Framework which aims to hide the heterogeneity of hardware, software, data formats and communication protocols that is present in today's pervasive environments. The proposed the authors' framework enables user applications to interact with data from a wide range of networked services/devices using a high-level, abstract interface that features Web Services standards. The work presented here proposes the extended framework in an earlier work for an effective integration of heterogeneous services/devices in pervasive environments.
