针对无线传感器网络存在的拥塞问题,设计一种基于领导者的拥塞控制算法,利用分布式动态系统的理论对拥塞问题进行建模,并证明了所提出的算法能够保证所有节点的发送速率收敛到可用的最小带宽,同时利用Lyapunov函数证明了所提出的算法在变拓扑网络结构下的有效性,仿真实验表明,基于领导者的拥塞控制算法能够很好地抑制无线传感器网络中的拥塞现象,保证较高的吞吐量和较低的网络延时,提高整个网络的服务质量。
In order to solve the congestion problem in wireless sensor networks, a leader-based congestion control algorithm is designed and the congestion problem is modeled using the theory of distributed dynamic systems. It is also proved that the proposed algorithm can ensure that the sending rate of all nodes converges to The minimum available bandwidth and the Lyapunov function are used to prove the effectiveness of the proposed algorithm under varying topology. The simulation results show that the leader-based congestion control algorithm can effectively suppress the congestion in the WSN, Higher throughput and lower network latency, improve the quality of service throughout the network.
