On-satellite distributed destroy-resistant networking method based on Gray code level weight

Abstract

The invention discloses an on-satellite distributed destroy-resistant networking method based on a Gray code level weight. The method comprises the following steps: setting a threshold between cluster members and a hop weight constraint between cluster heads to perform Gray code addressing on all nodes; calculating a Hamming distance between nodes in each cluster and a total communication distance between the clusters, and dynamically adjusting a distance weight matrix between cluster heads; if the source node and the target node are in the same cluster, performing intra-cluster communication, otherwise, performing inter-cluster direct communication when the inter-cluster communication total distance is smaller than or equal to the inter-cluster member threshold value, and performing inter-cluster indirect communication when the inter-cluster communication total distance is larger than the inter-cluster member threshold value; and when the cluster head fails, triggering a cluster head fault-tolerant mechanism of the on-satellite distributed survivability networking. According to the method, efficient intra-cluster and inter-cluster communication can be realized, and meanwhile, the robustness of the network and the communication reliability are improved.
