Wireless ultraviolet communication uses the scattering action of gas molecules and aerosol particles to transmit information.It has the advantages of good confidentiality,non-line-of-sight transmission,small background noise and strong anti-interference ability,it has widely application prospect in military field and complex environment.With the deepening of research,point-to-point small-scale communication has been unable to meet the needs of multi-node communication,and it is urgent to study ultraviolet Ad Hoc network communication.UV mobile Ad Hoc network is flexible and can expand the communication range,but the characteristics of without central nodes and frequent topology changes,it is great significance to research on routing protocol of wireless ultraviolet mobile Ad Hoc networks.In this thesis,the following work have been done on the research of wireless ultraviolet mobile Ad Hoc network routing protocol:1.According to the scattering and absorption characteristics of ultraviolet by atmospheric particles,the line-of-sight communication and non-line-of-sight communication link model between ultraviolet communication nodes are analyzed.2.The Ad Hoc on-demand multipath distance vector routing algorithm(AOMDV)of ultraviolet Ad Hoc network is analyzed.The algorithm implementtation process and ultraviolet AOMDV routing process are given.The NS2 software is used to simulate and analyze the difference between AOMDV and multicast Ad Hoc on-demand distance vector(MAODV)in different scenarios.Finally,the AOMDV routing algorithm is improved in the residual energy of the node,and its performance is analyzed.3.The routing performance of ultraviolet Ad Hoc network in mobile state is mainly studied.The mobile Ad Hoc network topology changes frequently.Firstly,the ultraviolet routing performance under different network topology models is studied.Secondly,the performance of four different ultraviolet communication links are selected under the node moving state is analyzed.4.Combined with the characteristics of ultraviolet transmission,a rotatable UV communication transceiver is introduced,and the process of node acquisition,alignment,tracking is analyzed.Outdoor point-to-point UV communication xperiments were carried out under good weather conditions.The experimental results laid a good foundation for further study of UV communication performance.The feasibility of UV Ad Hoc network communication is verified by the above work analysis.The research results of this thesis provide a theoretical basis for the design of UV mobile Ad Hoc network routing protocol.This thesis consists of 39 figures,8 tables and 68 references.
