Energy Harvesting for Wireless Sensor Networks
Source: Sensors Online
The key to making energy harvesting work is to minimize the power required by the entire
system-sensors, conditioner, processor, data storage, and data transmission. Because
the sensors tend to be in sleep mode most of the time, they draw little current. At intervals
controlled by a randomization timer, the nodes wake up and transmit bursts of data.
MicroStrain's WWSN ad hoc network architecture allows thousands of multichannel, uniquely
addressed sensing nodes to communicate to a central, Ethernet-enabled receiver with
extensible markup language data output. Time division multiple-access is used to control
communications.
