Performance Of DTN Bundle Routing Protocol In Deep Space

Over the years, we never stop to explore the outer space. We have the passion andeager to know what the outer space is. The huge differences between deep spaceenvironment and terrestrial environment, and the great difficulty in physicalimplementation, make the erection of space Internet is still a vision of futurearchitecture. But this does not stop us from the research of deep space technology. Withthe gradual implementation of the deep space exploration program，we speed up theresearch steps.Deep space network has several features such as frequent link interruption, longtransmission delay, high error rate and low transmission success rate and so on. Thesefeatures are restricted on the usage of TCP/IP protocol which is widely successful usedon the ground in the outer space. In order to make it real in the outer space, with thegreat effort of the researching engineers, the new communication protocols for DTN arecoming. After many years of research, the concept of DTN (Delay/Disruption TolerantNetwork) catches people’s attention. As a new technology of networking with featuresof message-oriented reliability and different structural protocol, it is known as aneffective way to solve the problems in DTN.This study will focus on the design of DTN bundle protocol which will be used inthe Mars exploration network. Based on the transmission requirements, I design a DTNused in Mars exploration on which I will research and simulate the performance of theDTN routing protocol. This paper puts forward a routing algorithm based on the shortestsingle hop and its improvement which based on the entire path shortest. With the help ofsimulation software such as STK, OPNET, MATLAB, I finished my research and verifythe performance of the algorithm.
