2.3 Introducing the ARM with a recurring example
We will exemplify concepts of the IoT ARM with a recurring use-case scene
(a.k.a ―Red Thread‖) throughout the document in order to facilitate the
understanding of the IoT ARM‘s concepts. This allows for complementing the
sometimes abstract and top-down discussions of IoT ARM concepts with a real
logistics use-case based on the WP7 use case of ―Transport Monitoring with
Smart Load Carriers‖.
The ―Transport monitoring with Smart Load Carriers‖ use-case scene shows
how ̳live‘ sensor monitoring of smart load carriers can prevent the transported
goods from being damaged due to environmental influences. The load carrier is
equipped with sensors and can communicate with other devices in terms of
wireless radio technology. With this hardware, every load carrier continuously
measures its environmental parameters and sends all measurements via the
embedded event service to the mobile phone of the truck driver who has
subscribed to this service. The business value of the scene is clear: In
transportation, there is a huge potential of novel logistics models such as
rescheduling at distribution centers based on the estimated quality of the goods
in order to reduce waste and finally get the products in good shape to the
consumers (see Figure 3 ).
Figure 3 : The recurring example (―Red Thread‖)To make the use-case description more concrete and easy to grasp, we present
the use-case from a user‘s perspective. This description augments the WP7
use-case story with security features:
―Ted is a truck driver transporting highly sensitive orchids to a retail store. After
loading the orchids on his truck, he attaches an array of sensors to the load
carriers in order to measure the temperature. While he is driving, Ted gets
hungry and decides to stop and have lunch. He parks the truck at a resting spot,
