  Sensor network - Wikipedia, the free encyclopedia
A sensor network is a computer network of many, spatially distributed devices using sensors to monitor conditions at different locations, such as temperature, sound, vibration, pressure, motion or pollutants.
Sensor networks are applied in a wide variety of areas, such as video surveillance, traffic monitoring, air traffic control, robotics, cars, home and health monitoring and manufacturing and industrial automation.
Data from the sensors is usually aggregated and analyzed by a computer outside the network.

 Wireless Ad Hoc Networks: Smart Sensor Networks
Large number of (mostly stationary) sensors: Aside from the deployment of sensors on the ocean surface or the use of mobile, unmanned, robotic sensors in military operations, most nodes in a smart sensor network are stationary.
Network self-organization: Given the large number of nodes and their potential placement in hostile locations, it is essential that the network be able to self-organize; manual configuration is not feasible.
In these networks, each node may be equipped with a variety of sensors, such as acoustic, seismic, infrared, still/motion videocamera, etc. These nodes may be organized in clusters such that a locally occurring event can be detected by most of, if not all, the nodes in a cluster.

 Protocols for Self-Organization of a Wireless Sensor Network
Wireless sensor networks are part of a growing collection of information technology constructs which are moving away from the traditional desktop wired network architecture toward a more ubiquitous and universal mode of information connectivity [2].
Although exact sensor data traffic properties are not known yet, it is clear that, due to the nature of the observed phenomena, the required bandwidth for sensor data will be low, on the order of 1—100 kb/s [1].
For a sensor network, in contrast, we are interested in prolonging the lifetime of the network.
