18.2.3 Challenges in Pervasive Computing
The requirements listed in the previous section are important challenges in pervasive
computing, which aims one in harmony with real world circumstance, including unexpected
human behavior, rapid deployment, or insuf?¬?cient computing infrastructure. In
this chapter, we motivate these challenges, and address an improvement in a special but
realistic case of pervasive computing, in addition to the improvement of triage by introducing
information technology.
Data integrity and latency will be improved by exploiting a wireless network, since the
input information can be collected through the network, even if emergency personnel do
not directly or indirectly give a triage tag to the person who is in charge of collecting the
information. However, this stands on the assumption that information once input can be

reached in a destination in the network for more than a while. This assumption does not
always hold in pervasive computing. Hence, data integrity and low latency in the semireachable
network is one of the challenges in pervasive computing.
Input throughput and availability against the network are further challenging requirements
in pervasive computing. The real world is not of course composed as a set of
packets like TCP=IP, but behaves as the real time system.
