Adhoc网络Internet接入的动态QoS研究

STUDY ON DYNAMIC QOS OF INTERNET ACCESS FOR ADHOC NETWORK

Adhoc与Internet混合网络的QoS策略不同于传统的QoS保障,针对Adhoc与Internet混合的泛在网络有效感知,提出一种新型的Adhoc网络Internet接入的动态QoS模型RATD(Resource Assignment and Traffic Detection)。该模型通过链路层信号测量激发网络上层的切换决策模块,基于网络接入点QoS状态、信道资源的实时监测与分配、应用业务类别以及呼叫接入方式,对已有的QoS成果进行拓展,提高了接入切换控制的效率,理论分析和仿真实验均验证了RATD模型的有效性。

QoS strategy of the hybrid network of Adhoc and Internet is different from the traditional QoS guarantee;the paper puts forward a new kind of dynamic QoS model RATD of Internet access for Adhoc network in light of the effective perception of the hybrid Adhoc and Internet ubiquitous network.The model employs the link layer signal measurement to stimulate the switching decision module on upper layer of the network,and expands existing QoS outcomes based on the QoS status at network access points,the real-time monitoring and distribution of channel resource,and the application business category and calling and accessing approaches,this enhances the efficiency of access switching control.Both the theoretical analysis and simulation experiment all verify the validity of the model RATD.
