Research Of Aerospace Network Access And Handoff Realizing Technology

The development of high-performance, secure, advanced aerospace network technology can not only make aerospace datas transmit securely,but also enable the interconnection and the intercommunication between the aerospace systems efficiently.More over,it establishs a solid basis of the strategic, operational and tactical actions that aerospace supports.In recent years, aerospace network has become the focus of national research because of its special location and its unique advantage of accessing to information.This network is different from traditional ground-based cellular mobile communication systems and satellite communication systems.Therefore this artical does research on the technology of accessing and switching about the aerospace network based on the aerospace network's own characteristics.At present,there are some problems in buliding the aerospace network.For example,Slow network-it requests good network before the fight;the network is not flexible and it has a poor real-time and a long time delay that it can not fight against dynamic targets ;network bandwidth is inadequate that it can not satisfy the requests of transfering and sharing the continuous video streaming and the high definition pictures.In a word,the existing network can not meet the Network Centric Warfare aerial reconnaissance to combat the demand for network integration.This article is based on the reseach of the existing space network ,by improving the accessing agreements and the switching algorithms that achieves fast aerospace network,accessing terminals quickly switch to the base stations of the aerospace communication networks as well as the nodes between the accessing terminals and the base stations of the aerospace communication networks can identify the client node information and link characteristics and configurate interface automatically.At the same time, this article puts forward the subject on accessing and switching about accessing terminals and also designs 3D simulation platform to enable more true and accurate simulation.The subject has used the current advanced 3D and C # simulation system:1. The use of XNA programming environment to build 3D simulation environment; 2.By the .Net development platform,use C # language to complete the overall design of simulation program.Simulation program verifies that the accessing and switching strategy of the aerospace network can satisfy the requests of its quick access and the switching process.It achieves the desired objective.
