The BASE Plug-in Architecture-Composable Communication Support for Pervasive Systems

Pervasive computing is based upon spontaneously networked devices that are invisibly integrated into everyday objects. Due to the integration and mobility of devices, pervasive systems can be highly heterogeneous and dynamic. To enable cost-effective application development despite such harsh conditions, we have developed the BASE middleware. In its original implementation, BASE relied on monolithic plugins to provide tailored support for different communication abstractions, protocols and technologies. In this paper, we describe and evaluate a major architectural redesign that introduces modular plug-ins. The key benefits of the new architecture are increased flexibility and code reuse due to the efficient runtime composition of plug-ins.
