简介：这篇文章提出一个新计划在延期高效地控制消息冗余性容忍的活动特定的网络(MANET)。网络的类通常缺乏端对端的连接。为了改善，发送消息的效率成功地被交付，多重消息拷贝路由协议通常被使用，但是网络负担由于很多消息冗余性被增加。在学习，由使用相反的方法，每个节点基于流行路由计划增加一个相遇柜台。柜台记录节点与一样的消息拷贝遇到另外的节点的数字。如果一个节点的柜台到达安装阀值，节点移开拷贝。理论分析在延期给阀值的更低的界限容忍的MANET。根据阀值的更低的界限，合理阀值在真实环境被安装。与建议计划消息，拷贝显然减少并且最后完全被移开。成功的交货效率仍然与流行路由一样，冗余的拷贝高效地被控制到一相对低级。计算机模拟在快、慢的活动性场面有关不同阀值给消息拷贝的变化。
