Some other important real-world applications/projects of WSN  are Wave Monitoring , Ocean Water Monitoring , Zebra Net , Cattle Herding , and neu RFon .
The maximum data rate for signal transmission is 250 Kbps but it depends upon the choice of configuration and the radio. The Direct Sequence Spread Spectrum (DSSS) secures the data transmission.
The positioning information technique like GPS-free localization , relative localization , or absolute localization  is used by the nodes to know about the transient nodes for communicating its data to far distant nodes or base station.
Current transmission techniques (e.g., Bluetooth) consume about 100 n J per bit for a distance of 10 m to 100 m, making communication very expensive compared to acquisition and processing .
Stateless and light-weight protocols, dynamic power adjustment, and different power saving modes are excellent candidate solutions to minimize computation and to save transmitting, receiving, sensing, and processing power to add more life to WSN in its constraint resource environment.
