A Resource Aware Software Architecture Featuring Device Synchronization and Fault Tolerance

We present a component-based software architecture that dynamically discovers and consumes remote services from distributed devices connected across a network. The architecture maintains its own local functionality, while also actively participating in its environment by discovering and responding to other devices as well. One novel capability of this software is its ability to synchronize its local and remote services with all other devices in its environment via its meta-architecture infrastructure. Furthermore, our architecture is fault tolerant and has the capability of re-synchronizing with lost connections and remembering old peers. The software architecture is built on top of the PRISM middleware and inherits much of its design style from the C-2 Architectural style. We have deployed our extensions to PRISM, and subsequent software architecture on a network of distributed devices that included Windows 2000 Pentium III-based computers, and wireless Compaq IPAQ PDAs and have created a sample application, a distributed calculator, as a proof of concept for our extensions.
