按需式ad hoc移动网络路由协议的研究进展

说明：  A d hoc 移动网络是一种完全由移动主机构成的网络. 网络拓扑易变, 带宽、能源有限是ad hoc 移动网络 的主要特点. 针对这些特点, 目前设计的ad hoc 路由协议大多采用按需查找方式. 该文介绍了这方面研究的最新进 展, 对几种典型的按需路由协议进行了说明、分析和综合比较. 文中分析了目前协议存在的一些问题并提出了相应的改进方法. 最后指出了下一步研究方向.
(d hoc mobile network is a fully mobile host of a network. Network topology variable bandwidth, energy is limited ad hoc mobile networks, the main features. These characteristics, the current ad hoc design of the routing protocol used mostly to search on-demand approach. The paper introduced the the latest research progress on several typical on-demand routing protocols for the description, analysis and compared. the text analysis of the current agreement of some problems and the corresponding enhancement. Finally, the next direction.)
