With rapid growth of the Internet of Things (TOT) technology, more and more sensors are deployed to sense various environmental parameters or transmitted signals. Many of such sensors, especially for remote wireless sensing applications, have a very limited operational lifetime. To collect all of the sensors after a project is complete could be costly, time-consuming, or impossible. However, leaving the sensors in place when they are no longer needed, may pose both environmental and information security risks.
Therefore, there is a need in the art for a cost-effective approach to manage such sensors after their useful life is over.
