A mote is a common term given to a wireless sensor device that represents a single node in a wireless sensor network. Each node consists of a small cpu, radio, and sensor board. When a mote is powered on, it forms an ad-hoc mesh network with any neighboring nodes that are in range. The nodes communicate with each other so sensor data can be routed through the network to a gateway computer for processing. Because of their small size, nodes are also known as Smart Dust. The term mote originates from dust motes, i.e. – a single piece of dust. Currently, motes are about this size of a match book, but are expected to shrink to the size of an aspirin or a grain of rice over the next few years.
