NTERNET of Things (IoT) has been emerging as the
next big thing in Internet. It is envisioned that billions
of physical things or objects will be outfitted with different
kinds of sensors and actuators and connected to the Internet
via heterogeneous access networks enabled by technologies
such as embedded sensing and actuating, radio frequency
identification (RFID), wireless sensor networks, real-time and
semantic web services, etc. IoT is actually cyber-physical
systems or a network of networks. With the huge number of
things/objects and sensors/actuators connected to the Internet,
a massive and in some cases real-time data flow will be
automatically produced by connected things and sensors. It is
important to collect correct raw data in an efficient way; but
more important is to analyze and mine the raw data to abstract
more valuable information such as correlations among things
and services to provide web of things or Internet of services.
This special issue features recent and emerging advances
IoT architecture, protocols, services and applications. More
than one hundred papers were received and peer-reviewed,
out of which thirty five papers were selected for publication,
which cover topics including sensors and devices for IoT,
efficient communications and networking for IoT, security and
privacy in IoT, crowdsensingand crowdsourcing, localization
and tracking, services and applications, and IoT data modeling
and management.
