| 摘 要： | 为了在Ad hoc网络中提供面向连接的服务,结合MPLS技术中标签交换路径面向连接的特性和多径路由的特点,提出了一种基于标签交换的Ad hoc网络多径路由(LSMR)协议。在源节点和目的节点间按需建立多条没有交叉节点的标签交换路径,使得数据包的转发完全在链路层完成,不需网络层的介入,加快了转发速度。仿真结果表明,LSMR协议比AODV协议能够降低端到端时延和路由负载,提高数据包的投递率。

| Abstract: | In order to provide connection oriented service in Ad hoc networks, a novel multipath routing protocol, label switching multipath routing (LSMR), is proposed by combining connection oriented property of label switched path in multi-protocol label switching (MPLS) technology and advantage of multipath routing. LSMR can set up multiple node disjoint label switched paths on demand between communicating nodes and allow the entire packet forwarding operation to be executed within the link layer without intervention of the network layer. Simulation results show that compared with Ad hoc on-demand distance vector routing protocol (AODV), LSMR can decrease end-to-end delay and routing overhead while packet delivery ratio is increased. |
