The congestion control algorithm based on leader is designed for network congestion of wireless sensor network. The congestion problem is modeled by using the theory of distributed dynamic system,which can prove that the send rate for all nodes converges to the minimal available bandwidth by using the proposed congestion control algorithm.By using Lyapunov function,the effectiveness of the proposed algorithm is proved under the varying network topology.Simulation results show that the proposed algorithm restrains the congestion in wireless sensor network,maintains high throughput and low delay time,and improves the quality of serve for the whole network.
