摘要:
可用带宽估计方法是提高网络QoS水平的关键技术。通过分析无线Mesh网络的特点与无线信号通信的特征，并建立信号信道容量与发送功率和接收功率在理想通信系统中的数量关系，建立了可用带宽与发送功率和接收功率的数量关系，提出了通过计算无线Mesh网络节点信号容量来估计无线Mesh网络链路可用带宽的方法，从而使得可用带宽估计方法在无线Mesh网络的估计结果更接近真实值。实验结果表明，该方法估计的结果更接近真实的可用带宽，在无线Mesh网络中的精确度要高于APEAB方法，可以为网络管理、流量控制和保证QoS提供参考
Abstract:
Available bandwidth estimation is one of the key technologies to enhance the network QoS level. An improved available bandwidth estimation method for wireless Mesh network is proposed. Firstly, the quantitative relation between signal channel capacity and sending/receiving power is determined by analyzing the features of wireless Mesh network. And then）the more accurate available band- width can be estimated based on the relation by calculating the size of signal node capacity within wireless Mesh network. Experimental results show that available bandwidth which proposed method estimates is closer to real usable value in wireless Mesh network,and its accuracy is better than APEB method. The estimated available bandwidth can provide the reference for network management s flOW control and QoS guarantee
