基于干扰模型的无线网状网QoS路由策略

WMN QoS routing strategy based on interference model

为支持无线网状网中多媒体业务,提出了基于干扰模型的QoS路由策略WQRI。首先对网络进行分层,然后提出新的可用带宽和端到端延时估计方法,在协议中实现可靠的接入控制和端到端资源预留。仿真表明,WQRI策略能以较低的控制报文开销为实时业务提供QoS支持。

To support multimedia applications in Wireless Mesh Networks （WMN）, the authors proposed an interference- based Quality-of-Service （QoS） routing strategy named WQRI. This strategy first stratified WMN and then proposed novel methods to estimate the available bandwidth and end-to-end delay. It achieved reliable admission control and resource reservation. Simulation results indicate that WQRI can provide QoS support for real-time applications at lower control packet overhead.
