Abstract
The fog computing (FC) model is proposed to efficiently realize the IoT (Internet of Things). In this paper, we consider the mobile FC (MFC) model including mobile fog nodes which communicate with other fog nodes in wireless networks. Here, each fog node is equipped with some process by which output data obtained by processing the input data from other nodes and devices is sent to other fog nodes in the opportunistic way. In the opportunistic protocols, each fog node exchanges only data with other fog nodes in the communication range. In this paper, we newly discuss the MFC model by which fog nodes exchange not only data but also processes with one another in the communication range. A node sends a process to another node which holds data to be handled by the process so that the electric energy to be consumed by the nodes can be reduced. Here, even if there are multiple target nodes in the communication range, a source node sends data to one of the target nodes. In this paper, we newly propose a parallel data transmission (PDT) algorithm where a fog node in parallel sends segments of data to multiple target nodes.
