A Wireless Sensor Network is composed of hundreds or thousands of nodes that can be equipped with limited energy resources, but can still be used over an extensive set of diverse applications such as environment monitoring, healthcare, homeland security, military surveillance, manufacturing, and industry automation. The physical layer parameter affects the performance of the network. In this circumstance, the authors analyze the best modulation scheme, and transmission approach to minimize the total energy consumption required to send a given number of bits. The total energy consumption includes both the transmission energy and the circuit energy consumption.
