Media Abstraction Framework for the Pervasive Middleware PalCom

• Pervasive middleware systems are important for enabling the configuration and coordination of the services provided by devices in pervasive environments. PalCom is an example of such a system that aims to enable interaction among pervasive services over heterogeneous networks. In this paper we discuss the need for providing networking-media independent messaging among pervasive devices, and identify the problem of designing a media abstraction framework for a pervasive middleware. We identify a number of design principles and features that need to be satisfied by such a framework. The most important of these principles is the separation of networking protocol aspects into abstraction representations, which are exposed in a unified format to upper layers of PalCom, and communication mechanisms which are hidden by media-specific implementations of our proposed media-abstraction framework for PalCom. Also, we explain our implementation and evaluation of that framework.
