IoT AND SMART INFRASTRUCTURE
George Lu, Yilin Yang · 2016
There is an increasing recognition that people's aging infrastructure needs to be monitored using the nascent Internet of Things (IoT) technology. Infrastructure monitoring is still in its relative infancy, though benefiting from rapid technological innovation in MEMS sensors, fiber optic sensors, wireless communication, embedded computing, and energy harvesting. This chapter discusses the engineering decisions. A significant part of wireless sensor research and field work is based on the assumption that people will use very low-power wireless sensors for infrastructure monitoring. Many industrial and infrastructure processes depend on Supervisory Control and Data Acquisition (SCADA) systems continuously for their critical missions. It is important to know the amount of time given to provide the needed control; there may be consequences of failing to provide the needed control signal in time. Such stringent performance requirement could constrain people's design decisions greatly.
