渗流理论与MANET模型相吻合，可以用于MANET网络的连通性问题，是一种新的移动的自组网拓扑控制策略。我们提出应用渗流理论改进移动的自组网的距离广播算法，节点到天线，只在特定扇区相关的方向上转发，实现广播消息的定向转发;我们用额外覆盖区域代替传统距离广播算法的距离阈值作为网络刚连通的临界概率阈值，提高了网络广播转发速率，降低了端到端时延，实现了节点能量的有效利用，从而达到网络节能的目的。通过仿真实验，与传统的远距离广播算法相比，该算法的分组投递率和平均时延都有很大的改善。
Percolation theory coincided with MANET model can be used for MANET network connectivity problems, and it is a new mobile ad hoc network topology control strategy. We propose the application of percolation theory to improve distance broadcast algorithm of mobile ad hoc network, the node to the antenna, only in specific sectors related to the direction of forwarding, realize the directed forwarding of the broadcast message; We use additional coverage area instead of the distance threshold of traditional distance broadcast algorithm as the critical probability threshold that the network is just connected, which improves the network broadcast forwarding rate, reduces the end-to-end delay, achieves the node energy effective utilization, and therefore attains the purpose of the network energy-saving. Through the simulation experiment, the packet delivery rate and average delay are improved greatly compared with the traditional distance broadcast algorithm.
