Fire is one of the few disasters that frequently occurred in Indonesia. Jakarta has archived 1139 fire incident with more than 20 casualties in 2016. By the rapid development of information technology and communication in Indonesia, it turns out that the number of incident and casualty still cannot be suppressed. This research is focused on early fire detection and home monitoring based on Wireless...
Several monitoring oriented applications in Wireless Sensor Networks (WSNs) are characterized by the necessity of two data-reporting modes: time-driven and event-driven. The former is used mainly for constantly supervising an area and the latter for event detection and target tracking.
