| 摘要: |
| MANET网络中拓扑结构频繁变化的特点,经常导致网络存在通信路径不稳定,通信质量较差的情况。文章提出一种基于灰色区域的移动预测路由协议LP-OLSR,该协议能够适应网络拓扑结构的快速变化,结合节点灰色区域范围,预测链路未来时刻的连接状态,在链路失效前重新计算路由,减少因为链路中断产生的时延。并且结合多径技术扩展至LP-OLSR-M协议,通过多径路由算法寻找一条备份路径,在当前链路即将失效前切换至备份路径,进一步保证了数据的稳定传输。仿真结果表明,新协议的QoS指标较OLSR协议相比有了明显改善,有效提高了MANET网络的通信质量。 |

| Abstract: |
| As is well known, the topological structure in MANET networks changes frequently, causing the link in-stability of data transmission path and the poor quality of data transmission.We propose a mobility prediction rou-ting protocol based on gray zone.Its core consists of: (1) it can adapt to rapid changes in network topology, com-bine the scope of the gray zone of a node with node location information to predict the future link state and recalcu-late its routing table before a link failure occurs, thus reducing the delay caused by link break; (2) when the rou-ting protocol predicts that the neighbor node is about to be in a gray zone, it immediately invalidates the neighborzone, avoiding the existence of an unreliable link; (3) we use the multi-path routing algorithm to extend the exist-ing OLSR routing protocol into the multi-path routing protocol (LP-OLSR-M) to find a backup path; it switches tothe backup path before a failure occurs to the current link path, thus further ensuring the data transmission stabili-ty.The simulation results, given in Figs.3 through 5, and their analysis show preliminarily that our routing proto-col remarkably increases the packet delivery ratio and decreases the average time in queue and the average end-to-end delay compared with the traditional OLSR routing protocol, being indeed effective for improving the data trans-mission quality of MANET networks. |
