3. Time required to input an injured person??™s information can be independent of the
network communication, since the information already input so far about the
injured person, which is shown to the emergency personnel when they begin to
add information, is not obtained through the network, but from the RFID tag.
This application addresses important challenges for pervasive computing: data integrity,
the information that should not be lost after being input; input throughput, the time
required to input injured person??™s information should be as short as possible; availability,
that is, emergency personnel should be able to use the system any time, and low latency of
communication. These should be as independent of the network status as possible.
In this chapter, we show a realistic solution for the challenges by specializing the
network usage in a way that only particular paths are used in particular stages of the
work?¬‚ow by analyzing the work?¬‚ow and exploiting RFID tags to slim down the possible
paths by the following approaches: input throughput and availability are assured by using
RFID tags as local buffer; data integrity is assured and latency is improved by de?¬?ning
minimum wireless communication areas in the paths in triage work?¬‚ow.
