Future directions of C3 research at DARPA (Defense Advanced Research Projects Agency)

Research into C3 related problems is a major effort of the Information Science and Technology Office of the Defense Advanced Research Projects Agency. The major thrusts of projects is in the area of future, high-risk efforts, often resulting in the development of a conceptual model or prototype. Some of these prototypes are then further developed to provide an infrastructure for future research. The programs can be divided into two groups: base technology research programs and testbed programs. The testbeds provide a focus for the technology programs

ARTÌS: a parallel and distributed simulation middleware for performance evaluation

This paper illustrates the motivation, the preliminary design and implementation issues, of a new distributed simulation middleware named Advanced RTI System (ARTÌS). The aim of the ARTÌS middleware is to support parallel and distributed simulations of complex systems characterized by heterogeneous and distributed model components. The ARTÌS design is oriented to support the model components heterogeneity, distribution and reuse, and to increase the simulation performances, scalability and speedup, in parallel and distributed simulation scenarios. Another design issue of the ARTÌS framework is the dynamic adaptation of the interprocess communication layer to the heterogeneous communication support of different simulation scenarios. In this paper we illustrate the guidelines and architecture that we considered in the design and implementation of the ARTÌS middleware, and we sketch some case studies that demonstrated the ARTÌS utility and motivation, e.g., a distributed simulation of massively populated wireless ad hoc and sensor networks
