Title Research of Routing Protocols of CubeSat network  Simulation and Optimization                      

Abstract

According to the features of the CubeSat network, the aim of this paper is making improvements in certain aspects to design a suitable routing protocol in the wireless communication condition, based on the existing mature study of Ad Hoc routing protocol.

First of all, this paper does some researches on satellite communication network, and then classifies the satellite network routing technologies, analyze the technical problems and difficulties needed to be addressed in applying the routing algorithm to the satellite network . Then the development process and meaning of Ad Hoc network are introduced. After that, through comparing and discussing the Ad Hoc network routing protocols, it comes to that the AODV routing protocol is the most suitable one to be improved. In following of the conclusion, the characteristics and mechanisms of AODV routing protocol are described in detail. At last, testing the AODV routing protocol under different conditions by simulation software, some performance indicators of AODV routing protocol are validated on the base of corresponding testing data.
