Social Sensing
Social sensing is an integral paradigm of the internet
of things, when the objects being tracked are associated with individual
people. Examples of such sensing objects include mobile phones, wear-
able sensors and piedometers. Such paradigms have tremendous value in
enabling social networking paradigms in conjunction with sensing. The
increasing ability of commodity hardware to track a wide variety of real-
life information such as location, speed, acceleration, sound, video and
audio leads to unprecedented opportunity in enabling an increasingly
connected and mobile world of users that are ubiquitously connected to
the internet. This is also a natural mode in which humans and things
can interact with one another in a seamless way over the internet. A
detailed discussion on social sensing may be found in [8].
Smarter Devices
In the future, it is envisioned that a variety of
devices in our day-to-day life such as refrigerators, televisions and cars
will be smarter in terms of being equipped with a variety of sensors
and will also have internet connectivity in order to publish the collected
data. For example, refrigerators may have smart sensors which can
detect the quantities of various items and the freshness of perishable
items. The internet connectivity may provide the means to communicate
with and alert the user to a variety of such information. The user may
themselves be connected with the use of one a social sensing device such
as a mobile phone. Similarly, sensor equipped and internet connected
cars can both provide information to and draw from the repository of
data on trac status and road conditions. In addition, as has recently
been demonstrated by the
Google Car
project, sensor-equipped cars have
the capability to perform assisted driving for a variety of applications
[124]. A further advancement of this technology and vision would be the
development of internet connected cars, which can perform automated
driving in a way which is sensitive to trac conditions, with the use of
aggregate data from other network connected cars.
Identification and Access Control
RFID tags can be used for a
wide variety of access control applications. For example, RFID sensors
can be used for fast access control on highways, instead of manual toll
booths. Similarly, a significant number of library systems have imple-
mented
smart check out
systems with tags on items. When the collected
data is allowed to have network connectivity for further (aggregate) anal-
ysis and processing, over multiple access points, this also enables signif-
icant tracking and analysis capabilities for a variety of applications. For
example, in a network of connected libraries, automated tracking can
