中文摘要：

MANET网络具有高速移动以及频繁的链路失败等特点，这将导致吞吐率降低以及很高的端到端时延．为减少由于此类原因的路由发现次数以及开销，我们使用多径路由来提供备选路径．论文提出一种基于AOMDV的改进链路独立多径路由协议．通过仿真表明改进后的LD—AOMDV在节点移动速度较高时数据包投递率、端到端平均时延、归一化路由开销等方面都明显优于AOMDV．

英文摘要：

Mobile ad hoc networks are typically characterized by high mobility and frequent link failures that result in low throughput and high end-to-end delay. To reduce the number of route discoveries and route overhead due to such broken paths, multipath routing can be utilized so that alternate paths are available. In this paper,we proposed a method LD-AOMDV to improve the AOMDV protocol. We use the simulation tool NS-2 and choose the packet delivery fraction, end-to-end average delay, normalized routing overhead to evaluate the performance. Results indicate that the LD-AOMDV protocol has better performance.
