Abstract

Based on IEEE 802.15.4 standard for Low-Rate Wireless Personal Area Network (LR WPAN), this paper proposes a frame size adaptive Medium Access Control (MAC) protocol Mean Burst length and mean Gap between bursts are measured by using training frames between two communication de-vices With the mean Burst and Gap values, an optimal MAC frame size to meet the required FER is calculated During communication period, FER is periodi-cally measured in a transmitting device If the measured FER is lower than the required FER, MAC frame size is increased, else vice versa Thus, channel re-sources can be more effectively utilized by sending optimal bits into one trans-mission frame The proposed scheme is evaluated under various wireless chan-nel conditions in terms of the achieved throughput Simulation results show that the proposed scheme achieves a much higher throughput than a non-frame size adaptive MAC protocol in LR WPAN does.
