【摘要】：为了减少容延网络的资源开销,研究者提出了单副本转发路由算法.研究发现,这些转发算法导致节点流量负载极度不均衡,使得那些连接度较大的节点产生了拥塞.针对该问题,提出了一种基于接收阈值的拥塞控制机制,可以有效降低节点拥塞.该机制使每个DTN(delay tolerant network)节点根据自身的拥塞状况动态调整自己的拥塞控制机制,而且该机制独立于节点所运行的转发路由算法,不影响路由算法对中继节点的选择,具有很好的普适性.为了验证所提出机制的有效性,将该拥塞控制机制与现有的SimBet路由算法加以结合,提出了具有拥塞控制功能的SimBetCC算法.实验结果表明,SimBetCC算法在取得很好的拥塞控制的前提下,其递交率和递交时延等性能方面均优于具有拥塞控制功能的FairRoute路由算法.
[Abstract]:In order to reduce the resource overhead of the delay network, the researchers proposed a single copy forwarding routing algorithm. It is found that these forwarding algorithms cause the extreme unbalance of the node traffic load, which makes the nodes with larger connectivity. A congestion control mechanism based on the receiving threshold is proposed, which can effectively reduce the congestion. Node congestion. This mechanism makes each DTN (delay tolerant network) node dynamically adjust its congestion control mechanism according to its own congestion, and the mechanism is independent of the forwarding routing algorithm run by the node. It does not affect the routing algorithm for the selection of relay nodes. It has good universality. In order to verify the effectiveness of the proposed mechanism By combining the congestion control mechanism with the existing SimBet routing algorithm, the SimBetCC algorithm with congestion control function is proposed. The experimental results show that, under the premise of good congestion control, the SimBetCC algorithm is superior to the FairRoute routing algorithm with congestion control function in the performance aspects of the delivery rate and submission delay.
