reliability and availability of the internet of things

The problem of reliability and availability of the internet of things (iot) from the point of view of the classical approach of reliability assessment using mil-hdbk 217 is discussed in this paper. with the classical approach of reliability assessment using mil-hdbk 217, only hardware reliability can be assessed, and the situation with the iot is more complicated: billions of different things (devices), software programs, and human users are involved (networked). the reliability and availability of the iot is not only a matter of a failure rate of elements (things), but also protocols, standardization, logistics support and other influences. the relation for the reliability calcuation of an iot system is proposed.
