| 摘 要： | 单向链路会对自组网按需距离矢量组播路由协议(MAODV)的路由维护机制造成一定影响,为提高通信的实时性和完整性,针对单向链路,提出了改进的路由算法MAODV-UNI. 在路由维护过程中及时对单向链路进行检测并做出处理,合理有效的利用单向链路,简化路由修复,有效提高了路由性能. 用NS2仿真平台进行仿真验证,模拟单向链路,将改进后的协议与原始的MAODV协议进行比较,结果表明MAODV-UNI算法在分组投递率和时延方面优于MAODV协议,证明了该协议的有效性. |

| Abstract: | Unidirectional links have impacts on the routing maintenance mechanism of origin multicast Ad hoc on-demand distance vector (MAODV) protocol. In order to enhance the real-time performance and completeness of communication, this article put forward an improved routing protocol MAODV-UNI for u-nidirectional links. It can improve the routing efficiency by detecting the unidirectional links timely dur-ing the route maintenance and reasonably use it. Then use NS2 to simulate MAODV-UNI and compare with the original MAODV protocol in the same scene with unidirectional links. It is proven that MAODV-UNI has advantages about packet delivery rate and delay that make it more effective compare with original MAODV. |
| Keywords: | mobile Ad hoc networks unidirectional link multicast Ad hoc on-demand distance vector protocol |
