为了在自组网与有线网混合的互联(混合)网络中支持视频流媒体应用并保证服务质量,在传统的网关发现方案的基础上采用以流为单位进行路由的方法,并添加了根据当前网络状态与请求接入的视频流媒体质量要求关系的准入机制。另外,在将自组网参数化建模的基础上研究了自组网网络规模与整个网络容量的关系。仿真实验结果证明:该方案可以保证接入的视频流服务都能满足服务质量(QoS)要求,且实际容量可以达到网络最大容量的理论值。
In order to support video streaming media applications and ensure service quality in the interworking (hybrid) network with ad hoc networks and wired networks, a method of routing based on the flow is adopted on the basis of a traditional gateway discovery scheme, Network status and request access to video streaming media quality requirements of the access mechanism. In addition, based on the parametric modeling of ad hoc networks, the relationship between ad hoc network size and the entire network capacity is studied. The simulation results show that this scheme can guarantee that all the video streaming services can meet the requirements of Quality of Service (QoS) and the actual capacity can reach the theoretical maximum capacity of the network.
