On the Efficient Implementation of a High Performance Multi-Agent Simulation System for Modeling Cellular Communications Involving a Novel Event Scheduling Algorithm

Simulation models are used in the design, development and evaluation of wireless communication systems. While basic network entities as Base Stations and users are always taken into account in such simulation modeling, a critical but currently underestimated factor that affects the simulated network behavior is the corresponding simulation model which represents the physical activities and the events of the network. A novel event scheduling mechanism for supporting concurrent network events and a novel network modeling methodology based on the multi-agent concept implemented through multi-threading technology is presented in this paper. The state of the art event scheduling mechanism supports only sequential events and on the other hand, the multi-agent technology has been used only for modeling network nodes. Additionally, the technical aspects of the multi-threading technology regarding the agent implementation and scheduling for simulating wireless communication systems has not been investigated so far in the literature. The proposed simulation framework in this paper gives improved solutions to the above issues. KeywordsEvent scheduling; multi-agents; network modeling; wireless network simulation
