Abstract: Transmit power control (TPC) technique is considered as a key solution for WBAN for low-power operations, which can be proactive or reactive depending on the channel conditions. While reactive approaches involve control packet overhead and additional delay, the proactive approaches are prone to prediction errors and involve prediction delay. Hence, a hybrid technique is needed which combines the advantages of both these techniques for all type of channel conditions. In this paper, an adaptive hybrid TPC (AHTPC) algorithm for WBAN is developed. In AHTPC, if the received signal strength indicator (RSSI) and packet delivery ratio (PDR) values fall outside the range of some lower and upper bounds, the reactive transmission power control algorithm (RTPC) is executed. If the difference of consecutive RSSI samples becomes larger, then proactive transmission power control algorithm (PTPC) is executed. From the simulation results, it is shown that AHTPC algorithm outperforms existing proactive and reactive techniques.
