一种分簇DTN中分层多摆渡节点路由机制

A hierarchical multiple ferries routing mechanism for clustered DTN

单摆渡节点路由机制在小规模聚簇DTN中有很好的工作效率,但是随着网络规模增大,该机制存在时延增大的缺点。为了解决这个缺点,设计实现了一种分层多摆渡节点路由机制,该机制为DTN分簇部署摆渡节点,通过摆渡接入点协调分簇摆渡节点与全局摆渡节点的通信。理论分析和仿真试验结果表明该机制可以很好地提高分簇DTN平均时延性能。

The single message ferrying routing mechanism works well in small-scale clustered DTN, however, as the network scale increases, this mechanism will suffer from high delay. Given this problem, a hierarchical multiple ferries routing mechanism is proposed. In this mechanism, message ferries are deployed in DTN clusters, and the ferrying access points are used to orchestrate the cluster message ferries and global message ferry. The theoretical analysis and the simulation results show that this mechanism can greatly reduce the average delay.
