Resilience in the Internet of things

Abstract—More than 6 billion pervasive devices have already
been deployed as of 2017. The capacity of IoT to monitor and
automatize any “thing” of the user every day life makes this
technology appealing to users and manufacturers. Accordingly,
companies can now offer offer new services, making them
more competitive and customer oriented. At the same time,
this paradigm attempts to combine opposing properties such
as affordability and security. Consequently, IoT is still facing
challenges regarding reliability and quality of service. This paper
provides a survey of IoT technologies and their security as well
as a summary of efforts made to increase failure tolerance of
pervasive computational systems.
