自适应无线传感器网络流量控制研究

无线传感器网络作为一种新型的具有广泛应用前景的无线自组网络，其有效路由协议是目前研究的热点。随着研究和应用不断深入，对传感器网络提出更高的要求：为不同的业务提供有保证的区分服务，同时能在全网范围内实现资源的充分有效利用。然而．随着传感器网络负荷的增加，拥塞将会导致网络性能的大幅下降。采用基于自适应的无线传感器网络流量控制机制，通过对拥塞节点的虚拟代价进行计算和判断，并实时地将虚拟代价发送到发送节点，然后对发送节点进行流量控制，在很大程度上改善网络性能，提高网络服务质量。

The Research on Free Fit with Wireless Sensor Network Rate Flow Control

As a novel kind of wireless Ad hoc network,wireless sensor network is of highly diverse applications,the efficient routing protocols of which is the focus of current research.With the continuous deepening research and application,the needs of differentiated services with QoS assurance to support heterogeneous telecommunication existing in wireless sensor network are becoming more and more egret,because it will have a direct influence on the overall performance and the practicability of the wireless sensor network.However,with increase of load in wireless sensor network,congestion will make performance of network bad quickly.Performance of network will be improved according to self-adapt based flow control mechanism for wireless sensor network,which calculates and judges virtual price in congestion nodes at first,and sends virtual price to sending nodes,then controls flow in sending nodes.
