Abstract

Complex and large-scale distributed systems are characterized by numerous interactive data communication among distributed components over network. This paper proposes a communication data multiplexing approach as an efficient message traffic reduction scheme. This approach encodes joint outputs of sender components into a single message and applies to a distributed system involving components moving and interacting in multi-dimensional space. For performance evaluation, this paper applies uses a projectile/missile case study with realistic multi-dimensional dynamics. This paper investigates variation of system accuracy and network bandwidth requirement, while a ratio of active components and a time granule are varied. Analytical and empirical data clearly indicate the advantages of multiplexing in saving communication resources in a large-scale distributed simulation. In addition, this paper discusses effectiveness and limitation of the multiplexing approach while considering the tradeoff between system accuracy and performance.
