无线误码信道上的拥塞控制策略

Congestion control scheme on wireless loss-prone links

主要讨论了无线网络拥塞控制的问题,基于将网络层和传输层策略相结合的思想,一方面在网络层,根据控制论中的不完全微分PID控制器思想设计了一种主动队列管理算法PID-AQM;另一方面,利用TCPW协议作为传输层策略,讨论了将二者相结合在无线网络中的拥塞控制性能。仿真结果表明,两种策略的结合大大提高了无线网络的传输效率。

The congestion control on wireless loss-prone links was discussed. According to the idea of combining network layer schemes and transport layer schemes, a new active queue management scheme based on PID controller with incomplete derivation was proposed on network layer. On the transport layer, TCPW protocol designed properly for wireless network was used. Simulation result shows that this method can greatly improve the transport efficiency on wireless network.
