Motes: tiny, smart, computers Motes have the ability to sense, compute and

communicate. Each mote in an ad hoc network wirelessly collects data and then relays the collected data to its neighboring motes and then to a central system or PC for processing.

An example of tiny, battery-powered computers called “motes”
