Interoperability Architecture for Simulators and Radio Models

Simulation is an important tool in developing and evaluating network and communication technologies, and many discrete event simulation (DES) systems have been developed. But each DES defines a unique interface between its core and radio models. Significant effort is required to port a radio model from one DES to another and then validate that the model"s accuracy has not been adversely affected. This process must be repeated each time the radio model is updated. Immediate, automatic conversion between DESs allows radio models to be effectively shared, shortening the development cycle, and accelerating the improvement of radio technology. IAI proposes to develop an Interoperability Architecture for Simulators and Radio Models (ISAM). ISAM serves as an adapter and creates an automated process for compiling and using existing radio models in any DES, regardless of which DES the radio model was written for. The key innovations of ISAM are: 1) a set of automated syntax and semantics translators which preserve model functionality and correctness, 2) a three-tiered adapter design that reduces complexity and allows translation component re-use, and 3) an intermediary common Application Programming Interface (API) to and from which all translation occurs and which allows users to directly write DES-agnostic radio models.
