An Energy-Aware Dynamic Algorithm for the FTBFC Model of the IoT.

Various types of devices are scalably interconnected in addition to computers like servers in the IoT (Internet of Things) and the IoT consumes large electric energy. In the FC (Fog Computing) model of the IoT, application processes for calculating on sensor data from devices are executed on both servers and fog nodes. The TBFC (Tree-Based FC) model is proposed to reduce the total energy consumption of the IoT. The FTBFC (Flexible TBFC) model is also proposed, where operations for changing the tree structure. In this paper, a DC (Dynamical Change) algorithm is newly proposed to change the FTBFC model where a node is changed each time the node is congested Here, the tree structure and processes supported by nodes are changed to reduce the total energy consumption. In the evaluation, the total energy consumption of the IoT is shown to be reduced in the DC algorithm.
