| 中文摘要: |
| 针对无线自组织网络现有按需路由协议在路由维护时需要采用全网洪泛广播路由请求消息而导致大量额外开销的缺点,提出了一种无线自组织网络基于洪泛控制的动态路由协议FCDR.FCDR的主要思想是控制洪泛机制的使用范围,减少路由的维护开销,并使失效路由得到快速恢复.文中描述了FCDR协议的实现过程并对路由维护时消息传递的有效性进行了分析.分析表明：通过广播路由请求消息建立路由的情况下,消息传递的有效性将随着源结点和目的结点之间路径长度的增加而急剧下降,相比之下,FCDR具有更好的有效性且其优势随着源结点和目的结点之间路径长度增加而更为显著. |

| Aiming at adapting broadcasting routing request message for on-demand routing maintenance in wireless ad hoc network and inducing much additional overhead, a Flooding-Controlled Dynamic Routing (FCDR) protocol was proposed. FCDR limits flooding within two hops of primary routing to decrease routing maintenance overhead and repair failed primary routing quickly, and then service stability. The message transmission efficiency of routing maintenance was analyzed. The analytical result shows that the efficiency drop rapidly with path length increment between source node and destination under the circumstance of no flooding-controlled. By contrast, FCDR has better efficiency and its advantage is more prominent with path length increment between source node and destination. |
