It is critical to design a reliable packet transmission scheme to improve throughput in Energy harvesting Wireless sensor network (EH‐WSN) or Battery free Wireless sensor network (BF‐WSN). We present the Optimal size and rate (OSR) scheme to improve throughput of communication links in the IEEE 802.15.4 based BF‐WSN that harvests radio frequency energy. Based on the de.ned truncated geometrical distribution, we formulate the optimization problem that maximizes the e.ective throughput of communication link. The solution of the optimization problem yields the optimal triple, namely the optimal packet size, data rate, and Maximum number of transmission trials (MNTT), which is used in the OSR so that throughput is considerably improved. Simulation results show the OSR scheme can improve throughput.
