摘要 针对MANET中AODV,DSR等典型按需路由协议未考虑负载均衡导致网络拥塞和性能急剧下降的严重不足,提出了新的路由机制-ALBQM(Adaptive Load Balance QoS Multipath).ALBQM主要包括:(1)QoS可用带宽的负载感知模型,减少网络冲突和拥塞;(2)采用最大不相关多径并行通信,自适应分配数据流量,提高数据递交率.基于OPNET网络仿真平台对ALBQM应用于DSR进行性能验证,与DSR及其多径路由SMR相比,在重负载网络中有更好的性能表现-在不增加额外控制开销的条件下提升数据递交率,减少端到端平均延迟及路由错误总数. Focusing on the serious deficiency of network congestion and performance decrease caused by typical on demand routing protocol AODV,DSR without considering load-balance in MANET,this paper proposes a novel adaptive load-balance QoS multipath routing mechanism（ALBQM）.It consists of i）QoS load awareness model of available bandwidth to avoid congestion;ii）adopt maximum irrelative multipath concurrently to improve throughput by distributing data packets adaptively.Simulation results on OPNET platform show ALBQM applied to DSR does a better job in heavy load environment—higher data delivery rate,lower average end-to-end delay and route error without additional control overhead,compared with traditional DSR and SMR.
