Autocorrelation Based Transmission Power Control in WBANs
2018 12th International Symposium on Medical Information and Communication Technology (ISMICT), 2018 In this paper, we propose an autocorrelation-based transmission power control (A-TPC) method to increase the transmission reliability and reduce the energy consumption. In A-TPC, data packets from multiple sensor nodes are scheduled in the TDMA-fashion.
