This article is about event detection for WSN. Wireless sensor networks (WSN) are a spatially distributed network of autonomous sensors used for monitoring an environment. Energy cost is a major limitation for WSN requiring the need for energy efficient networks and processing. One of major energy costs in WSN is the energy spent on communication between nodes and it is sometimes desirable to only send data to a gateway node when an event of interest is triggered at a sensor. Sensors will then only open communication during a probable event, saving on communication costs. Fields interested in this type of network include surveillance, home automation, disaster relief, traffic control, health care and more.

has abstract	This article is about event detection for WSN. Wireless sensor networks (WSN) are a spatially distributed network of autonomous sensors used for monitoring an environment. Energy cost is a major limitation for WSN requiring the need for energy efficient networks and processing. One of major energy costs in WSN is the energy spent on communication between nodes and it is sometimes desirable to only send data to a gateway node when an event of interest is triggered at a sensor. Sensors will then only open communication during a probable event, saving on communication costs. Fields interested in this type of network include surveillance, home automation, disaster relief, traffic control, health care and more. Energy savings come from the fact that nodes only communicate back to the gateway when there is an event to report. This may be difficult in dynamic environments where much of the data collected may not be of interest. To overcome this issue constraints on what defines an event are relaxed and usually modeled as a set of thresholds or probabilities. Event detection falls under three main categories: threshold based, supervised and unsupervised. (en)
