Maximum supported network coverage area and cost evaluation of key pre-distribution schemes
Yuan Xue, Helmut Jürgensen · 2008
Sensor nodes are low-cost computing devices combining wireless transmitters with specialized sensors, such as temperature, humidity, light, motion, speed, acoustic, chemical and seismic sensors. Sensor nodes are typically deployed in great density over a large geographical area. After deployment, these nodes organize themselves into an ad hoc network to gather the required information from the target environment.
