Congestion control algorithm for power internet of things based on bandwidth estimation

In order to improve the throughput of power Internet of Things and reduce end-to-end delay, a congestion control algorithm based on bandwidth estimation for power Internet of Things is proposed. Build the architecture of the power Internet of Things, and estimate the bandwidth of the power Internet of Things from the perspectives of the bandwidth of the external channel of the node and the bandwidth occupied due to the queuing delay according to the architecture characteristics. According to the bandwidth estimation results, the power Internet of Things congestion control is carried out to maintain the power Internet of Things traffic load balance. The experimental results show that the highest throughput of the algorithm in this paper is close to 500 Mb• s-1, and the end-to-end delay is low, and the delay is within 3s, which verifies its application effect.
