A Web-based distributed computing framework for antenna array modeling

The purpose of this article is to present a distributed computing framework that is used as a purely Web-based simulation environment for antenna array modeling. The framework adopts a three-tier architecture. The front-end part is mainly based on dynamic Web pages for the selection of antenna parameters, enhanced by the VRML standard for visualization of the geometry and results. The middle part of the architecture is based on Java servlets, which are responsible for handling the front-end communication with the remote user and setting up the simulation. Finally, the back end of the architecture is responsible to distribute the computations to a set of computing nodes. This part employs a purely Web-based mobile agent platform, responsible for the execution of partial simulation code to remote hosts. In the context of the article we demonstrate the applicability of the framework in antenna array modeling by presenting a specific parametric simulation of conformal antenna arrays.
