机会网络模拟器ONE及其扩展研究

摘要

网络仿真是DTN网络研究的重要方法和手段.通过对ONE模拟器的开发背景、结构、功能及其应用的介绍,探讨与分析了基于Java环境的DTN网络模拟器ONE的扩展方法,进一步对ONE的不足之处进行了完善和改进,并通过仿真实验证实了改进的ONE对路由性能评价的影响.%Network simulation is an important method in the area of delay tolerance network research. This paper introduced the development background, composition, function and application of opportunistic network environment ( ONE ). It analyzed the extending method of ONE which was Java-based simulator for DTN. Finally, improved some deficiencies of ONE and presented simulation results to prove the improvement of ONE in the area of routing performance evaluation.
