A data compression based power aware BAN system exploration of IEEE 802.15.6

Several access modes and access methods, combined with new power management schemes and frame structures are defined in the latest IEEE standard 802.15.6. To improve power efficiency of body area network, data compression was studied in this paper. Moreover, an analytical model was developed to evaluate the power efficiency of BAN system. Simulation results show that good power efficiency can be achieved by data compression. It also proved that higher data rate can help to improve energy efficiency. When its compression factor is bigger than 2 and its power consumption does not exceed 40% of the transceiver, better energy efficiency always can be guaranteed by processing unit insertion.
