Deployment Automation for Blockchain Enabled IoMT

Abstract

Every kind of software system needs an update one or the other day. One such update could be a routine software patch, security patch or a total periodical system update. As the field of Internet Of Medical Things (IOMT) is emerging drastically day by day with huge network of devices connected over internet, comes the challenge of software update Over The Air (OTA) to all the connected target nodes of a wireless sensor network without interrupting the services for longer time. Considering crucial applications of Internet Of Things (IOT) like Health Care, Smart Grids or any other sensitive environments where response time of the system is very less, while applying a software patch or security patch to the concerned device has to be done as quickly as possible, which keeps the services uninterrupted, which requires smart patching. Ideally zero downtime is desired in such critical applications, which is still a long way to go. This article presents a way of deploying the software patches to the IOT systems with multiple features which helps to reduce the downtime of the system over Secure Shell (SSH) Communication Protocol.
