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.
Unidirectional links will affect the MAODV routing maintenance mechanisms to some extent. To improve the real-time and integrity of the communication, an improved routing algorithm is proposed for unidirectional links MAODV-UNI.It detects and processes the unidirectional links timely and effectively in the process of route maintenance, and makes use of the unidirectional links reasonably and effectively to simplify the route restoration and improve the routing performance effectively.Using NS2 simulation platform to simulate and verify, One-way links. The improved protocol is compared with the original MAODV protocol. The results show that the MAODV-UNI algorithm is superior to the MAODV protocol in terms of packet delivery rate and delay, which proves the validity of the protocol.
