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
