“…It can adopt the space-based and the class-based schemes. Principally, the interest manager module is a federate that follows the general publish-subscribe model of interest management, which is inherently adopted in the HLA standard [18]. Publishers are entities that send data, whereas subscribers are entities that receive data.…”

Abstract:In networked driving simulation, two or more human drivers participate interactively within a shared virtual environment. Thereby, typical applications of driving simulation can be extended to consider multi-driver scenarios, where a much closer approximation of reality with its unpredictability is achieved. However, the utilized network is typically prone to a considerable amount of message traffic. In addition to restricted system scalability, the resulting degradation of network performance leads to invalid simulation outcomes or unacceptable system behavior. High-Level Architecture (HLA) is the IEEE standard 1516 that provides specific guidelines for networked simulation. Data distribution management (DDM) is one of the service groups provided by the HLA standard. The aim of the DDM service is to reduce network traffic and to save effort required to process unnecessary received data. However, existing approaches for current DDM implementations show major drawbacks in terms of utilization complexity, inefficiency, and yet added network overhead. This paper presents a new concept of an interest manager that takes over the DDM functionality and avoids these drawbacks. Simulation data is exchanged between the participating driving simulators only when it is necessary according to the driving situations. The interest manager was implemented and its efficient functionality was validated by analyzing the network load of two driving maneuvers with and without the interest manager.

“…The bucket synchronization algorithm [6][7] was proposed by C.Diot and L.Gautier, which was first used in multiplayer online games MiMaze for DIS-based simulation based on serverless P2P architectures. In this paper, some of the ideas of bucket synchronization algorithm are borrowed, and the synchronization algorithm of frame bucket locking is proposed based on the idea of online game synchronization.…”

Abstract-In order to guarantee the synchronization of multi-simulation entities in the multi-channel 3D visual simulation system, the dynamic synchronization method is of great significance. By improving the traditional bucket synchronization algorithm, the paper presents and implements the frame bucket lock synchronization algorithm, which effectively solves the problem of image ghosting and tearing that may occur when the moving entity traverses the critical region of the three-dimensional virtual simulation system of multi-channel ship driving. Ensure the critical channel screen seamless stitching. By introducing the RakNet network engine to ensure the reliability of data transmission, a motion smoothing algorithm with cubic spline interpolation is proposed, and an effective method to deal with the smoothing of the ship is given. The experimental results show that the proposed algorithm is feasible and feasible to solve the multi -channel synchronization problem of multiathletic entities in three -dimensional ship driving virtual machine, and the display effect is better.
