A green energy consumption policy of Bluetooth mobile devices for smart cities

Green computing mode becomes a social concern in recently years. Consequently people have higher demand for Bluetooth device with lower power consumption. In this paper, a green energy consumption policy (ECP) of battery of Bluetooth devices during data transmission was put forward. ECP extracted detail information from four key configuration parameters during Bluetooth data transmission, namely, transmission mode, connection type, packet type and communication rate. Based on the verification data time, verification data transmission time and Bluetooth package time acquired by the computer processor unit, it calculated the battery energy consumption during equipment idle. Moreover, it calculated the actual transmission data and energy consumption according to the data size of the transmitted document. A simulation analysis on ECP was carried out in this paper. Results showed that ECP could estimate energy consumption for document transmission in the independent Bluetooth communication module.
