交替活跃模式网络数据转发调节机制

Forwarding Adjustment of Network in Alternate Activity Mode

提出了适用于具有交替活跃模式的部分连接网络的数据转发调节机制。延迟转发对于部分连接的网络是适用的,给出了延迟转发方式中的等待时间估计方法,通过基于状态机的自适应发送窗口调节方法,根据邻居的交替特征预测节点维持活跃状态的概率,调整转发包的速率,有效地减少了由于节点状态交替变化导致的丢包现象。网络仿真结果表明,该方法能够显著提高包递交率,并降低端到端延迟。

This paper proposes a scheme of forwarding in partially connected network based on alternate activity mode. Delay of forward is suitable for partially connected network. An evaluation of delay period is given. A self-adjustment scheme based on state machine is introduced. By tuning the size of forward window according to the evaluation of activity of neighbors, packet loss is reduced. Simulation shows that this method can increase the packet delivery ratio and reduce the end-to-end delay.
