摘要

MANET中节点移动造成路由中断带来端到端传输性能下降

为解决这一问题提出了一种适用于分段运动模式的链路稳定概率计算方法

并在此算法的基础上设计了一种适用于分段运动模式的基于链路维持概率的跨层路由协议(LPCP)。LPCP跨层结合路由层和传输层

能够兼顾端到端连接的稳定性和最小跳数。制定了"路由切换"、"数据存储转发"、"ACK再确认"等机制尽可能减少路由中断的发生及其带来的端到端传输性能下降。仿真结果表明LPCP能够有效减小路由中断带来的丢包

提高端到端传输吞吐量。

Abstract

The end to end transmission performance is very poor because of routing failure caused by node movement in MANET.To solve this problem

an algorithm for the link duration probability of epoch-based movement was proposed

and based on which a link duration probability based cross-layer routing protocol for epoch-based movement（LPCP） was proposed.LPCP cross-layer interacts with transport layer

and considered both the maximum path availability and the minimum hops of an end to end connection.Three complementary mechanisms:routing switch

save then forward

ack reconfirm were proposed to prevent routing failure and the transmission efficiency reduction.It is shown by computer simulation that LPCP results in a significant improvement of the packet loss caused by routing failure

and increase the throughput much more.
