ENERGY EFFICIENT MIDDLEWARE FOR DYNAMIC DATA DRIVEN APPLICATION SYSTEMS

Middleware is required to support and interface multi-modal Dynamic Data Driven Application Systems (DDDAS) with back-end and other computing facilities. Middleware is also needed to support distributed simulations and emulations needed in earlier phases of system development. This work describes the Green Runtime Infrastructure (G-RTI), an energy-efficient client server based middleware developed to support distributed DDDAS simulation, emulation and deployment. G-RTI eases and accelerates the development and testing of multi-modal studies, testbeds and DDDAS systems. It serves as a platform for research in energy reduction techniques for middleware services. The services implemented by G-RTI are described and results of benchmarking studies are reported. Its application is demonstrated through a use-case for an end-to-end implementation of a connected vehicle application. G-RTI is open source.
