The Research of One Self-Adapt Wireless Sensor Network Rate Flow Control

The wireless sensor network is a new kind of wireless ad hoc network and highly applications prospects. The efficient routing protocol is the focus of researching. Now we request the sensor network more and more strictly demand with the deepening research and application. However, the congestion will make decrease performance of network quickly with the increase of data load in wireless sensor network. The network performance will be improved according to the self-adapt 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. This will promote the transmission quality of network data frequency to a new higher level.
