HLA-based Adaptive Distributed Simulation of Wireless Mobile Systems
Wireless networks’ models differ from wired ones at least in the innovative dynamic effects of host-mobility and open-broadcast nature of the wireless medium. Topology changes due to simulated hosts’ mobility map on causality effects in the “areas of influence” of each mobile device. The analysis of wireless networks of interest today may include a potentially high number of simulated hosts, their respective computationally-relevant protocol stacks, and their complex, causally-determined aggregate behaviors. Simulation requirements determine memory- and computation-bottlenecks resulting in performance and scalability problems for discrete-event sequential simulation tools and methods, on a single physical execution unit (PEU). In a distributed simulation, objects defined as logical processes share causal effects as events implemented by message-passing primitives. The main bottleneck becomes the communication and synchronization required to maintain the causality constrains be...
