摘要
移动自组织网络中多径路由为流媒体业务提供了实时及可靠的数据传输,然而大多数多径路由协议忽略了多条路径间的干扰问题。利用802.11协议中MAC层RTS/CTS机制标识节点的干扰状态,提出基于地理位置的无干扰多径路由协议RGMR(a Radio-disjoint Geographical Multipath Routing for MANET)。通过对干扰节点的标识,使得干扰节点无法参与路径的构建,从而寻找出多条互不干扰的路径,提高了网络的吞吐量,降低控制开销和端到端时延。
Muhipath routing in MANET provides real-time and reliable data transmission for stream media services. However, most muhipath routing protocols ignore the interference problem between paths. By marking the interference status of nodes with MAC layer RTS/ CTS mechanism in 802. 11 protocol, we propose a radio-disjoint geographic muhipath routing (RGMR) protocol. Through marking the interference node, the inference node has no possibility to take part into the construction of paths, thus it is able to find out numbers of non- interfering paths, the network throughput is improved, and the control overhead and the end-to-end delay are reduced.
