文章摘要
大地震发生后,地震紧急救援通信系统发挥着“时间就是生命”的重要作用。震后灾区的电力、通信、交通等基础设施被毁坏,这给在“黄金72小时”内利用有限的人力物力资源迅速建立地震紧急救援通信系统提出了巨大的挑战。分析黄金时间内地震救援的特性需求,基于DTN(Delay Tolerant Network)网络模型提出地震紧急救援通信系统,同时设计适合于地震救援系统的DTN路由策略和多个移动模型并分析网络时延。最后,通过实验仿真分析不同移动模型对网络通信质量的影响,?渴鸬卣鸾艏本仍ㄐ畔低程峁┝擞幸娴牟慰肌?
Abstract
Emergency earthquake relief communication system plays the important role of "time is life" after the big earthquake. The electrical power system, communication system, transportation system and other infrastructures are destroyed in earthquake zone, this brings a huge challenges to establishing the emergency earthquake relief communication system rapidly in “Golden 72 Hours” under the limited human and material resources. In this paper, we analyse the particularity demands of the earthquake relief in “Golden 72 Hours”, and propose an emergency earthquake relief communication system based on the DTN network model, meanwhile we design the DTN routing scheme suitable for the earthquake relief system and several mobile models, and analyse the network delay. Finally, we analyse the influence of the different mobile models on the quality of networks communication through simulation experiment, which provides a beneficial reference for the deployment of emergency earthquake relief communication system.
