通过对现有定向扩散协议的研究,考虑到无线传感器网络对于各节点的能量和整个网络的开销的要求,提出将逾渗算法应用于定向扩散协议的兴趣扩散阶段。定向扩散协议的兴趣扩散是以广播的形式发送数据,而逾渗算法的加入是使各个节点以一定的概率p(p<1)发送数据给邻居节点,只要这个概率值大于或等于整个网络连通的临界值,就能保证这个网络中的各个节点都能顺利地接收到信息,并同时达到减少网络开销的目的。
Based on the research of existing directional diffusion protocols, considering the requirements of wireless sensor networks for the energy of each node and the overhead of the whole network, the percolation algorithm is proposed to apply the percolation algorithm to the stage of interest diffusion of directional diffusion protocols. The interest diffusion of directional diffusion protocol is to send data in the form of broadcast, while the percolation algorithm is to add each node to send data to the neighbor node with a certain probability p (p <1), as long as the probability value is greater than or equal to the entire network connection The critical value, can guarantee every node in this network can receive the information smoothly, reach the purpose of reducing the network expenses at the same time.
