The demand for wireless sensor networks (WSN) has increased and attracted worldwide attention. Advances in microelectromechanical systems (MEMS) technology have facilitated the development and implementation of smart sensors. Smaller sensors are small, inexpensive, require little power and, with limited process resources, are less expensive to produce than traditional smart sensors. Sensor nodes have the ability to detect and measure, and depending on various process characteristics, they can collect information from different environments and transmit the processed data to the user's field.
