Virtual Storage System based on Multiple Embedded Devices in IoT Environments

In this paper, we propose a virtual storage system based on the multiple embedded devices in IoT environments, which builds the storage by reusing the remaining storage space of the existing embedded devices. The virtual storage system consists of a client, a gateway and multiple embedded devices. The client transmits various types of data to the gateway. The gateway divides the data transmitted from the client as the multiple blocks, and then transmits each block considering the remaining storage space of the embedded devices. The embedded device stores the blocks transmitted from the gateway or returns the current storage information. We implement the proposed virtual storage system to verify the feasibility of the proposed system. The implementation results show that the proposed virtual storage system has the advantages in terms of cost-efficiency and scalability.
