An Efficient Time Management Scheme for Large-Scale Distributed Simulation Based on JXTA Peer-to-Peer Network

As an emergence technology, P2P is spreading to distributed simulation area, and many distributed simulation frameworks have used P2P as the middleware to interconnect their existing single processor´s simulators to form distributed environments for simulation execution. In terms of simulation time management, most existing tools use a middleware layer to implement and support time management in a heterogeneous networking environment, and therefore, it is generally not easy to migrate a single processor´s simulation to multi-processors in these frameworks. In this paper, we present a P2P based distributed simulation time management based upon JXTA API and Service Oriented Architecture (SOA), and we focus our discussion on how we implement the time management as a JXTA peer and a JXTA group service. Our time management is actually a native distributed message passing management framework, and does not rely on any middleware layer. Furthermore, we evaluate the performance of our implementations using a local Linux cluster. This work will establish a solid foundation for the more advanced distributed simulation services that have been proposed in our project [1].
