摘　　要：随着造船工业和水上航运业的发展,船舶的数量迅速增长,船舶之间的通信需求也随之增加。船与船组网构成了船舶自组网,现行无线自组网路由协议家族很庞大,但没有专门为船舶自组网而设计的,且现有的路由协议在船舶自组网中性能不佳。为提高路由协议在船舶自组网中的性能,文中对船舶自组网的特点进行分析,研究常用的动态源路由(DSR)的优势和劣势;其次,对DSR进行改进,采用动态标签的方式对转发分组头部携带的路由信息进行优化,采用主被动相结合的邻居发现策略减少路径表达带来的路由开销,使其更好地适用于船舶自组网;最后,在Exata平台上进行仿真实验。结果表明,优化的DSR协议能够减少路由开销,吞吐量提高30%左右,平均时延降低约10%,网络传输性能整体上有所提高。With the development of ship building industry and water shipping industry,the number of ships has increased rapidly,and the demand for communication between ships has also increased.The ship Ad Hoc network is composed of ship and ship networking.The current wireless Ad Hoc network routing protocol family is very large,but it is not specially designed for ship Ad Hoc network,and the existing routing protocol has poor performance in ship Ad Hoc network.In order to improve the performance of routing protocols in ship Ad Hoc networks,the characteristics of ship Ad Hoc networks are analyzed,and the advantages and disadvantages of dynamic source routing(DSR)commonly used are researched.The DSR is improved,and the routing information carried by the forwarding packet header is optimized by dynamic labeling.The active and passive neighbor discovery strategy is adopted to reduce the routing overhead caused by path expression,so that it can be better applied to ship Ad Hoc networks.The simulation experiment is carried out on Exata platform.The results show that the optimized DSR protocol can reduce routing overhead,improve the throughput by about 30%,reduce the average delay by about 10%,and improve the overall network transmission performance.
