一种应急通信中业务感知的宽带自组网路由协议

随着科技进步，我国在应急通信系统建设上也正高速发展，当前应急通信网络对多媒体业务有着迫切需求，对网络带宽要求更高。而当网络存在多种不同业务时，传统通用的路由协议不再适用，它们大多以最小跳数为路由度量或者是某个单一度量，未能考虑不同业务的服务质量(Quality of Service, QoS)需求，因而无法同时兼顾不同业务流的传输要求。提出了一种应急通信中业务感知的宽带自组网路由策略，对不同类型业务在路由和转发优先级上进行区分。经多次仿真验证，该策略能使网络在满足应急语音业务QoS需求的同时，也能兼顾承载的视频、数据等其他业务的性能。

A traffic-aware broadband ad hoc network routing protocol for emergency communication

The construction of emergency communication system in China is developing rapidly.The current emergency communication network urgently needs rich communication services and broadband access.However,in multi-service networks,traditional ad hoc routing protocols with a single metric,such as minimum hops,end-to-end delay,or available bandwidth,cannot meet the transmission quality of service(QoS) requirements of different services.Thus,a traffic-aware routing strategy for broadband emergency communication network is proposed.The proposed strategy distinguishes the routing and forwarding priorities according to QoS requirements of different services.The simulation results show that this strategy can meet the QoS requirements of delay-sensitive service and guarantee the performance of other multimedia services at the same time.
