“…Traditional row-based storage systems have to read many unrelated data from data repository, so they have performance limitations when handling a number of concurrent, diverse queries. However, in column-based storage model, only the columns related to IoT query need to be taken from the data repository, which is densely compressed to improve read efficiency like the column-store [10] [11]. Since IoT devices have very limited storage space, all data collected or generated should be sent to the storage server.…”

Sensor network consists of a large number of sensor nodes that combine physical sensing capabilities with networking capabilities. The objective of this research is to introduce the base architectures of IoT sensor network, fog computing and edge computing technology. In this paper, a new approach of handling IoT data is proposed for efficient data service in IoT environment. Proposed scheme can transmit compressed sensor data by reducing overhead in advance through column-based data compression.

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. This study introduces architectures of IoT sensor network, data control schemes, fog computing and edge computing technology. This study also reviews the requirements of IoT service from the aspects of transmission, storage and computing, and analyzes data balancing and data recovery. This paper also proposes a data management scheme called DaRM, utilizing dual IoT gateways to provide efficient and stable data service in IoT environment. DaRM exploits both edge gateway and fog gateway to improve data reliability and communication efficiency. DaRM can transmit compressed sensor data by reducing overhead in advance through delayed replication and column-based data compression.

This paper proposed a new replication management scheme for IoT sensor network environments. Replicating data across multiple nodes can increase the reliability for the shared data. However, data replication inevitably results in overhead of maintaining data consistency, especially in the event of excessive sensor node failures, requiring more costly synchronization mechanisms. In order to lessen the overhead of excessive node failures in fault-prone IoT sensor networks, a new scheme called sensor delegation con-sensus (SDC) was devised in this study. SDC minimizes the message exchange overheads of performing quorum access processes by means of viable deputy polling method which uses strong sensor nodes except unreliable nodes in polling process. This paper also proposed a computer simulation system to present the efficiency of SDC scheme. The performance evaluation results showed that the SDC model outperforms traditional replication management models.
