摘要/Abstract

摘要： 针对DTN中支持时效性和资源敏感型服务的质量保证问题,引入INSIGNIA跨层思想和PBNM模式,设计出一种分布式服务质量保证系统——DTN弹性质量自适应原型系统,并针对原型系统,对以往路由协议进行改进,提出自适应种子喷射和焦点路由协议。最后运用ONE网络仿真软件对原型系统的性能进行分析和评估。实验结果表明:与MaxProp协议和Epidemic协议相比,运用弹性质量自适应原型系统,能够降低消息的丢包率、端到端时延和路由开销,提高消息发送的成功率。

关键词: DTN,ASSFR,弹性质量

Abstract: Taking supporting the timeliness and resources sensitive service quality assurance in DTN as research background,this paper integrated the cross layer ideas of INSIGNIA architecture and intelligent management mode of PBNM architecture to design a distributed quality assurance system -- DTN resilience quality adaptive system．What’s more,this paper improved previous routing protocol,proposed a new routing protocol,called Adaptive Seed Spray and Focus Routing．Lastly,this paper used ONE network simulation software to analyze and estimate the performance of prototype system． The result indicates that compared with the MaxProp routing protocol and Epidemic routing protocol,the prototype system can reduce the messages lose rate,end-to-end delay,routing overhead,and improve message delivery successful rate.

Key words: DTN,ASSFR,Resilience quality
