Reliable Informational Data and Secured Deviation Notification over Networks Using IOT

Abstract

The need of uninterrupted services from servers, networks and databases in the current environment relying completely on computing technologies. This paper implements Automatic database duplication with one master database server and multiple slave database servers. The proposed system ensures slave database server replicates data of master server which can be used to restore services in case master server fails. Existing method does this with human intervention which is a time consuming process. Therefore, the proposed system ensures to implement automatic failover capabilities with relatively low downtime and notifying the same using smart alert system. The alert mechanism includes sending an encrypted message notifying the master failure, any deviation from normal working of automatic up gradation software. The messages exchanged are AES encrypted using Message Queuing Telemetry Transport (MQTT) as IOT protocol. The proposed system implemented with Arduino, Sensors and java keycards. Results prove automatic failover utilizes less resources and system downtime is almost zero compared to manual failover. Analysis of performance, System downtime, time estimation is carried out to check the time required for key generation and encryption.
