一种间歇性连接移动网络自适应路由协议

摘要

In order to improve the efficiency of message transmission in intermittently connected mobile networks,an Adaptive Routing Protocol Based on OLSR (ARPBO) of mobile ad hoc network is proposed.ARPBO forwards messages rapidly by the OLSR protocol when the network is connected.When the network is interrupted,ARPBO extends the OLSR protocol,selects the next hop node effectively by the message transmission node's local connected network,and then forwards messages through the "store-carry-forward" mechanism of delay tolerant network.The experimental results show that the proposed routing protocol can achieve higher message delivery success ratio and lower delivery delay when the network is intermittently connected.%为提高间歇性连接移动网络的消息发送效率,提出一种基于移动自组网OLSR协议的自适应路由协议ARPBO.ARPBO在网络连通时通过OLSR协议快速转发消息;在网络中断时对OLSR协议进行扩展,从消息发送节点的局部连通网络中有效选择下一跳节点,然后通过延迟容忍网络的“存储-携带-转发”机制转发消息.实验结果表明,该路由协议能够在网络存在间歇性连接时获得较高的传递成功率和较低的传递时延.
