Recently a great deal of attention has been dedicated to the design of virtual environment based class of applications. So far, a significant body of work has been devoted to the challenges of 3D streaming with a desktop scenario; whereas a little research work has been committed to 3D streaming on thin mobile devices that mainly focused to address challenges such as streaming performance, bandwidth...
Large-scale HLA-based simulations are susceptible to performance issues caused by load imbalances. High Level Architecture (HLA) was designed to organize distributed simulations, but it does not provide any mechanism to prevent imbalances. Also, several load balancing schemes have been proposed to properly re-arrange simulation load, but they do not present all the features needed for large-scale...
HLA-based simulations can experience performance degradation due to communication latencies between simulation federates, which generate significant cumulative overhead. Even though the HLA standard provides mechanisms to decrease the misuse of network resources, it does not present any tool to diminish the communication latencies between interactive federates. Moreover, the interaction dependencies...
Distributed Virtual Environment (DVE) has attracted much attentions in recent years due to the rapid advances in the areas of E-learning, Internet gaming, human-computer interfaces, and etc. Meanwhile, in recent years, the emergence of Service Oriented Architecture (SOA) provides a more flexible and inter-operable framework for building more advanced DVE based applications. In such a background, service...
HLA-based simulations, as any distributed computing application, can undergo critical performance issues due to load imbalances on large-scale, heterogeneous, non-dedicated distributed systems. Such imbalances are produced by HLA simulation entities that can dynamically change their computation and communication load during their execution time, so an initial static load deployment is incapable of...
Load balancing techniques have been widely used in many existing distributed system and simulation frameworks. With the rapid development of virtual simulation technologies, many researchers have been investigating on how to apply virtual simulations to the distributed environment, especially when the virtual simulations need to be expanded to large-scale. In this paper, we propose an adaptive load-balancing...
Dynamic load balancing is a key factor in achieving high performance for large scale distributed simulations on grid infrastructures. In a grid environment, the available resources and the simulationpsilas computation and communication behavior may experience run-time critical imbalances. Consequently, an initial static partitioning should be combined with a dynamic load balancing scheme to ensure...
Federate migration is a fundamental mechanism for large-scale distributed simulations. It provides the means for simulation load-balancing and thus improves the simulation's overall performance. Given its importance for simulations, several federate migration approaches have been proposed in the literature. Some approaches freeze the entire simulation, others use third-party mechanisms to transport...
