| Abstract: | In this paper,an equivalent energy consumption model of per data bit is founded and the optimum conditions of the lowest energy consumption is proposed from both net circuits and transmission channel in ARQ protocols for wireless sensor networks.By means of MATLAB imitation,the impact of frame error ratio and frame length and circuits parameters on energy consumption of ARQ protocols is analyzed under AWGN.The optimum frame error ratio and the optimum frame length are also discussed on lowest energy consumption. |

| Keywords: | wireless sensor networks energy efficiency frame error ratio optimal frame length ARQ protocols |
