| 摘 要： | 移动自组网络的路由算法往往采用传统的单路径路由方式，每次路由发现泛洪都会伴有大量路由包的丢弃以及路由负载和路由延迟的增加，大大降低路由算法的性能。为解决这些问题，提出了一种基于稳定的网格多路径路由算法SGMR.该算法充分利用网格中节点的位置信息，有效限制路由查询包的泛洪区域，并结合预测策略和节点不相交路径策略来选择多条稳定的节点不相交路由。模拟结果显示，与传统的单路径路由算法LAR和AODV相比，SGMR算法可以有效提高数据包投递成功率，降低路由平均延迟和路由负载。

| Abstract: | Most of the routing protocols for current ad hoc networks relies on traditional unipath routing.Each routing discovery flood is associated with much routing packet losing,higher routing delay and higher routing load.To overcome the shortcomings of unipath routing protocols,a new multipath routing algorithm called stability-based grid multipath routing(SGMR),was proposed.SGMR fully utilizes location information,effectively confines the flooding area of routing query packet,and uses prediction strategy and no... |
