All such papers do not deal with wireless simulation approaches, and simulation is only seen as a side-means to produce numerical results. This paper does not present simulation numerical predictions. It instead deals with new simulation approaches for wireless systems and presents simulation software technologies. From the approach point of view, the "local" versus the "distributed" simulation approach is investigated to wireless systems. From the technology point of view, two new software tools are presented, for a step forward with respect to existing tools to ease the development of distributed simulation systems. The tools consist of a new distributed simulation environment (wDSEnv) and a new distributed simulation language (wDSLang). Such tools are described and a detailed WiMAX local and distributed simulation example is developed. {\textcopyright} 2010 IEEE.}, keywords = {Computer simulation languages, Computer software, Distributed approaches, Distributed simulation environments, Distributed simulation systems, Distributed simulations, Fuzzy control, IEEE 802.16, Interoperability, Numerical analysis, Numerical predictions, Numerical results, Simulation approach, Simulation result, Simulation software, Software tool, Wimax, WiMax wireless, Wireless simulation, Wireless systems}, isbn = {9780769540214}, doi = {10.1109/AICT.2010.66}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-77955389670\&partnerID=40\&md5=b2c180074951949ca03eb646f638f842}, author = {Iazeolla, G. and Pieroni, A. and Andrea D{\textquoteright}Ambrogio and Gianni, D.} } @conference {D{\textquoteright}Ambrogio2007210, title = {Software technologies for the interoperability and reusability of distributed simulators}, booktitle = {SISO European Simulation Interoperability Workshop 2007, EURO SIW 2007}, year = {2007}, note = {cited By 2}, pages = {210-219}, abstract = {Giving interoperability and reusability capabilities to distributed simulators is fundamental to the widespread use of distributed simulation. The HLA standard has introduced considerable improvements with respect to previous standards, though it suffers from shortcomings such as (1) lack of interoperability among different IEEE-compliant implementations, (2) no support to the adaptation and integration of individual federates and (3) poor reusability, which is limited to entire federates only. In this paper, we present two independent technologies that overcome such shortcomings. The first technology consists of a CORBA-HLA architecture that overcomes limitation (1), the second technology is a new development framework called SimJ that overcomes limitations (2) and (3). The CORBA-HLA architecture decouples federates from the specific HLA implementation so that federates can be effortlessly run on top of any HLA implementation that exposes services through an IEEE-complaint IDL interface. The SimJ framework eases the development of individual federates by providing a uniform and standard interface for local and distributed simulators, and makes it possible the reuse of components smaller than entire federates in both local and distributed simulators.}, keywords = {Adaptability, Common object request broker architecture (CORBA), Computer architecture, Computer software reusability, Distributed simulations, Framework, HLA, Interoperability, Middleware, Reusability, Simulators, Software technology, Standard interface, Technology}, isbn = {9781615671700}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-84865354509\&partnerID=40\&md5=3cad39842c91176c439ae7bf7e6b17a1}, author = {Andrea D{\textquoteright}Ambrogio and Gianni, D. and Iazeolla, G.} } @article {D{\textquoteright}Ambrogio2006121, title = {Soon: A tool for software performance validation}, journal = {International Journal of Modelling and Simulation}, volume = {26}, number = {2}, year = {2006}, note = {cited By 4}, pages = {121-128}, abstract = {The automatic derivation of software performance models from CASE documents is a necessary step towards lifecycle validation of the performance of software products (or prediction of the product ability to satisfy the user performance requirements).

The model building activity is a critical and effort-consuming activity. Several approaches have been envisaged to endow software designers with tools that automatically build ready-to-evaluate performance models from software development models. One essential requirement of such tools, often disregarded by current approaches, is a high degree of interoperability with software development tools, which has the positive effect of reducing both the level of required expertise in performance theory and the burden of learning separate tools. This paper introduces a frame-work for transforming source software models into target performance models. The transformation requires a clear understanding of the abstract syntax and semantics of both the source and target models, which is obtained by use of metamodeling techniques for defining the abstract syntax of models, the interrelationships between model elements and the model transformation rules. In the paper case, the framework is applied to the transformation of source models of UML type into target models of LQN (layered queueing network) type. The proposed approach is founded on the precepts recently introduced by model-driven development (MDA) and makes use of the set of related standards (MOF, QVT, XMI). This allows to obtain a high degree of automation, so that interoperable model transformation tools can be implemented in a timely and efficient way, leading to improvements in terms of software designers{\textquoteright} productivity and system quality.

The High Level Architecture (HLA) is a standardization effort that provides a general framework for promoting interoperability and reusability in the simulation field. When applied to distributed simulation HLA shows some drawbacks that limit the desired degree of interoperability and reusability. This paper proposes a CORBA-based approach to overcome such drawbacks and improve HLA capabilities.
