Abstract:

Sensor nodes in a WSN are powered by batteries and have the ability to sense, process information, and communicate. For analysts, the power consumption of sensor nodes presents a number of challenges. A battery provides limited vitality to the sensor nodes. Because of the large number of sensor nodes and their location in remote, dry, or hostile zones, it is extremely difficult to replace or revive the battery of a sensor node. The detecting and sending processes require energy from sensor nodes. It is necessary to build these nodes to be energy efficient in order to reduce the amount of energy used by the sensor node when the battery life is limited. In situations where a system must operate for a lengthy period of time on battery power, energy savings are critical.
