| 摘 要： | 一般的无线通信网络严格按照协议栈逐层通信,虽然易于实现但同时也在一定程度上降低了网络效率和性能,使得在一些特殊应用场景条件下不能满足需要.为了解决问题,结合战术应用背景需求,分析了战术数据链的网络特性,采用跨层设计的方法,设计并实现了一种基于QualNet仿真环境的跨层通信机制.仿真结果表明,数据传输能够一定程度摆脱逐层通信的束缚,快速地进行跨层交互,减小协议栈里高层协议与低层协议的传输延迟,提高了信息更新的实时性.同时由于通信层次减少,消息传输可靠性得到提高,对战术数据链的应用具有重要的现实意义.

| Abstract: | The efficiency and performance of wireless network are lowered due to strict layered communication which is easy to design but can't meet the demand of some special applications usually. On the background of tactic application requirement, the characteristics of Tactic Data Information Link network are analysed and a Cross-Layer communication mechanism based on QualNet is designed in this paper to solve the problem. As it is shown by simulation results, without the restriction of layerd framework, data-tran... |
