针对月面人机联合探测网络的节点备份机制
Regarding the node backup mechanism of the lunar surface human-machine joint exploration network
摘要
Abstract
This article proposes a distributed node backup strategy to address the network disconnection issue caused by node failures in the lunar surface human-machine joint exploration network.Firstly,considering the unique characteristics of lunar missions and their networking methods,we model the lunar surface human-machine joint exploration network by categorizing the behaviors in the network and imposing constraints on the node behaviors.To reduce the information overhead maintained by each node,critical points are determined by two-hop neighbor information,and the critical points select backup nodes based on principles such as node type,recovery cost,and impact on the network using one-hop neighbor information and Hello message information.When recovering from failures,the independence of node tasks is considered,and a fault propagation strategy is used to offset the responsibility of moving astronaut nodes.Experiments demonstrate that this node backup mechanism can generate a backup recovery path for each critical node in the network with redundant nodes,and can reconnect the network without moving astronaut nodes.关键词
