e authors decided to integrate the sensors and actuators into an IP network because of its
ability to connect to more types of devices as compared to specialized protocols. e sensors were
connected using wireless LAN in order to reduce installation time and costs, and nodes are not
powered by batteries because of the high power draw of the transceiver.
Nodes are able to be autodiscovered by the system, configuring themselves into the network by
what information they gather and can provide. e sensor data can stay up to date by either pro-
gramming the nodes to send data to the network at intervals or getting t ...
