Energy consumption model. This figure shows the first order radio model which is used as the energy consumption model that is considered in this paper. Eelec is the amount of energy required to transmit and receive one bit message, and εamp is the amount of energy required to amplify the transmitter signal. The energy consumption of transmission and reception are denoted as ET and ER, respectively
