| 摘 要： | 传感器网络负荷的增加,将导致网络出现拥塞,拥塞会使网络的性能大幅下降。只有采用有效的流量控制,才能解决网络拥塞问题,改善网络性能,从而提高服务质量。自适应的无线传感器网络流量控制方法,计算拥塞节点的虚拟代价,判断拥塞节点的拥塞程度,实时地将拥塞节点的虚拟代价告知它的前跳节点,由前跳节点对流入本节点的数据流量进行控制,从而达到传感器网络的流量控制。

| Abstract: | It will cause congestion of sensor network,that the network load increases.The performance of network will decreased greatly.Effective traffic congestion control will improve performance of network and quality of service.Adaptive wireless sensor network traffic congestion control mechanism,which based on calculation of the virtual cost,judge and send it to former hop nodes of the congestion nodes real-time.Then the former hop nodes will control the input flow of the congestion nodes. |

| Keywords: | wireless sensor network flow rate queue length virtual cost flow control |
