In order to solve the problem of congestion in wireless sensor networks（WSNs） used for power user electric energy information acquisition and ensure monitoring fidelity of network at the same time

a congestion control algorithm based on theory of multiple attribute decision-making is proposed.The algorithm effectively combine features of power user electric energy information acquisition system

ignores node energy factor and considers the node congestion level

hop count

channel occupancy rate as basis for selecting next hop node.The algorithm builds selection model based on multiple attribute decision-making theory and accurately and effectively choose the next-hop node according to node comprehensive measurement values

so that the distributary path is established

and relieve network congestion.The experimental results show that the algorithm increase throughput of network and reduce transmission delay

so good network capacity and real-time can be obtained.
