Notice: As of 2014 and for the forthcoming years, the publication frequency/periodicity of NAUN Journals is adapted to the 'continuously updated' model. What this means is that instead of being separated into issues, new papers will be added on a continuous basis, allowing a more regular flow and shorter publication times. The papers will appear in reverse order, therefore the most recent one will be on top.

Abstract: Edge computing refers to decentralized computing technology to reduce cloud computing's overload or security problems that redirect local data to a central data center. Edge computing is emerging as a technology that complements cloud computing in an IoT environment where huge amounts of data are generated in real time. Recently, solid state drives using flash memory have recently been recognized as a suitable storage for massive IoT data services. In this study, we propose a new data recovery scheme based on shadow paging using flash memory for effective and safe data services in IoT edge gateways. The proposed scheme recycles invalidated old data blocks that are discarded when new data is stored. Thus, The proposed scheme minimizes the burden of additional storage space required to traditional shadow paging schemes, and reduces I/O performance degradation. Simulation results show that the space gain of the proposed scheme reaches even to 29%.
