| 摘 要： | 基于滑模变结构机制,讨论了节点级和链路级同时发生拥塞情况下的无线传感器网络跨层拥塞控制问题.对于节点级拥塞和链路级拥塞分别提出了准滑模控制策略.链路级拥塞采取节点输出流量最小的数据包优先进行传输的原则,实现了拥塞控制的跨层设计,大大降低了各节点排队时间,能够有效缓解拥塞的发生.仿真结果表明,该算法实现了较高的吞吐量和较低的延迟,提高了整个网络的服务质量. |

| Abstract: | Cross-layer congestion control for wireless sensor network based on sliding mode variable structure is considered,for which node-congestion and link-congestion are occurred simultaneously.A discrete quasi-sliding mode control based on node-congestion and link-congestion is presented.Min-data package of node outgoing traffic is prioritized transmission in link-congetion.Cross-layer design of congestion control is significantly achieved.The algorithm can reduce queue time and alleviate congestion.Simulation results show that the algorithm can restrain the congestion in wireless sensor network,maintain high throughput and low delay time,and improve the quality of service for the whole network. |
| Keywords: | wireless sensor network sliding mode cross-layer congestion control |
