Synchronising ‘heartbeat’ saves sensor batteries
“PUMPING” data around a wireless network of sensors - just as blood is pumped around the human circulatory system - could allow the sensors’ batteries to last four times as long.
Sensor networks like the ones used for environmental monitoring are usually “tree-like”. Their branching structure means information gets from A to B quickly, but means devices have to be turned on permanently to co-ordinate the data traffic.
