A Novel Approach for Distributed Simulation of Wireless Mobile Systems

Abstract. This position paper introduces the motivation and preliminary implementation issues of a distributed simulation middleware designed to increase the performance and speed-up in the distributed simulation of wireless systems characterized by mobile hosts. Topology changes due to simulated hosts’ mobility map on dynamic causality effects in the ”areas of influence” of each mobile device. We analyze the preliminary definition of a new dynamic mechanism for the runtime management and distributed allocation of model-components executed over a cluster of Physical Execution Units (PEUs). A migration mechanism dynamically adapts the topology changes in the wireless network to a reallocation of model components over the PEUs. The aim is the reduction of communication overheads, between the PEUs, required to distribute the event-messages between model components. The distributed simulation framework is based on HLA-compliant runtime infrastructure and preliminary, adaptive load-...
