摘要
目前针对移动自组织网提出的路由协议普遍存在路由发现和路由维护效率低的问题,在研究按需距离矢量(AODV)路由算法的基础上,提出了一种水下多路径选择按需距离向量算法(MAODV)。该算法采用多节点路由切换机制,在一条链路失效后不必重新启动路由发现过程,而选用备用节点构成新的链路,继续进行数据包的传输,大大节省了信息资源和带宽。计算机统计仿真表明,该MAODV方法的性能在端到端通信的平均时间延迟和数据包接收率上均优于(AODV)。有效地解决了路由协议中路由发现和路由维护效率低的问题。
Several routing protocols of MANET are inefficient in routing-finding and routing maintenance. Based on the research of AODV routing protocol, we propose a new AODV routing protocol for underwater multi-access nodes. The protocol uses a multi-node routing switch method, which does not startup routing-flnding over again but chooses standby nodes fmding routing to form a new link when the originally link is invalided. The new link continues transmit data packets. This routing protocol saves information resource and bandwidth significantly. Simtflation shows that the performance of MAODV routing protocol is better than the AODV routing protocol in average time delays of the end-to-end, and in inceptor ration of data package. MAODV effectively solves the problem that protocols of MANET are inefficient in routing-finding and routing maintenance.
