摘要： 传感器网络负荷的不断增加导致网络性能大幅下降，针对该问题，文章提出基于比例分配的无线传感器网络信息流调度模型，通过采用对拥塞节点的若干个前一跳节点按比例获取信息流代价，以调整流入拥塞节点信息流的方法，来防止网络发生拥塞。结果表明，该方法控制流入拥塞节点的信息流的大小，可避免因控制流入拥塞节点的信息流而导致的若干个前一跳节点发生严重拥塞。

Abstract: As to increase of load in Wireless Sensor Network(WSN) leading to performance of network bad quickly, a scheme based on proportion distribution information flow scheduling module for WSN is brought forward. Congestion in WSN can be prevented by introducing a method which distributes flow into congestion nodes by distributing information cost to former hop nodes of congestion nodes according to some proportion. Result turns out that this method not only controls flow rate into congestion nodes, but also avoids serious congestion in former hop nodes.

Key words: proportion distribution, Wireless Sensor Network(WSN), information flow, information flow cost
