| 摘 要： | 在无线网格网下提出一种通过提高发生拥塞的业务最大传输机会以缓解拥塞状况的拥塞策略,依据发送队列状态调整最大传输机会,增加拥塞节点中的拥塞业务的传输机会。对仿真数据分析结果表明网格网络的吞吐率、丢包率等重要网络性能都有明显改善,策略与IEEE802.11s草案中的拥塞机制相比,能够有效缓解网络拥塞,提高网络性能。

| Abstract: | This paper proposed a new congestion control approach by increasing the transmit opportunity of the congest access category to release the congestion status.This approach adjust the transmit opportunity based on the status of the corresponding access category’s transmit queue.Analysis of the simulation data in Network simulator shows better performances in many network factors such as throughput,packet loss rate,etc.The result proves that this approach can relieve network congestion and improve network performance effectively compared with the other congestion control mechanisms in IEEE802.11s draft. |
