Structural health monitoring system using IOT and wireless technologies

Structural Health Monitoring is the appearing field in civil engineering which offers the potential for continuous and periodic assessment of the safety and integrity of civil infrastructures. It includes process of identifying and detecting weaknesses and damages in the infrastructure due to aging or any other reason, well in time so that a preventive maintenance can be undertaken before it collapses. It can also give warning about current state of the structure. Internet of things (IoT), is the network of smart sensors that combine sensing and wireless transmission of vital safety parameters of buildings and structures, to distant computing units which continuously do the processing and monitoring of these parameters. This paper surveys the state of the present research in the technologies and implementation practices and tries to do a comparative analysis.
