在物联网的雾计算模型中,处理传感器数据的应用进程的子进程在雾节点上执行。由于物联网是可扩展的,我们必须减少电能消耗。在基于树的雾计算(TBFC)模型中,雾节点是分层结构的。在本文中,我们提出了一个容错TBFC(FTBFC)模型。此外,我们新提出了一对容错策略。在一种数据传输策略中,由断开连接的雾节点处理的数据被发送到新的父雾节点。在这里,我们提出了一个最小能量(ME)算法来选择一个新的父雾节点的能量消耗是最小的。在另一个子进程传输策略中,故障fog节点的子进程被发送到另一个fog节点。在评估中,新的父雾节点的能量消耗和执行时间可以减少ME算法。
In the fog computing model of the IoT, subprocesses of an application process to handle sensor data are performed on fog nodes. Since the IoT is scalable, we have to reduce the electric energy consumption. In the tree-based fog computing (TBFC) model, fog nodes are hierarchically structured. In this paper, we propose a fault-tolerant TBFC (FTBFC) model. In addition, we newly propose a pair of fault-tolerant strategies. In one data transmission strategy, data processed by disconnected fog nodes is sent to a new parent fog node. Here, we propose a minimum energy (ME) algorithm to select a new parent fog node whose energy consumption is minimum. In another subprocess transmission strategy, the subprocess of the faulty fog node is sent to another fog node. In the evaluation, the energy consumption and execution time of a new parent fog node can be reduced by the ME algorithm.
