摘　　要：无线自组网中无线频率资源严重受限,设计有效地利用无线带宽的路由协议是为多媒体提供服务质量保证(QOS)的重要内容。文中基于优化的链路状态协议(OLSR)及其扩展的最短路径算法,与多点中继技术(MPR)选择算法OLSR-R1及路由计算新量度mhMBW相结合,提出了基于有效带宽保证的路由协议——OLSR-BW。OLSR-BW比纯链路状态路由降低了控制开销,对于保障高速多媒体的连续顺畅传输起到重要的作用。The radio frequency resource in Ad Hoc is severely constrained, the design of routing protocol for effective use of wireless bandwidth is an important content for in providing important QOS guarantee for multimedia transmission. Based on the agreement of Optimized Link State Routing （OLSR） and its extended shortest path algorithm, and in combination of Multipoint Relay （MPR） algorithmOLSR-R1 with the new routing calculation measure mhMBW, the routing protocol OLSR-BW is proposed in order to guarantee the available bandwidth. OLSR-BW reduces more control overhead than pure link-state routing, and plays an important role in guaranteeing the continuous high speed multimedia transmission.
