移动自组织网络路由协议多是基于双向链路提出,而单向链路在实用环境下普遍存在,严重影响着网络性能.本文在路由发现、双向链路感知和路由维护等方面对AODV路由算法进行改进,提出了一种基于单向链路的优化路由算法AOD-VUD.仿真实验表明该算法显著改善了报文端到端传榆率,相对于现有按需路由算法AODV和AODVUU有较显著的优势.

Mobile ad hoc routing protocols are designed based on bidirectional links,but there are many unidirectional finks in real en-vironment,and they have bad effect on the routing protocols.In this paper we propose AODVUD,which is an optimized routing al-gorithm for ad hoc network with unidirectional links.AODVUD is based on the AODV routing protocol and uses some optimized method to improve the performance,which are routing discovery,bidirectional link sensory and on-demand routing maintain.Simula-tion experiment shows that AODVUD evidently increases the packet delivery ratio and has superiority compared with AODV and AODVUU.
