Many MAC (Medium Access Control) protocols have been taken to decrease the energy consumption of sensor nodes such as IEEE 802.11, 802.15.4 MAC or sensor MAC (S-MAC) protocols. In this paper, we provide analyses performance of IEEE 802.11, 802.15.4 MAC and S-MAC protocols in terms of throughput, energy consumption and data packet delivery. Our simulation results show that S-MAC protocol with active and sleep cycle consumes energy less than about 10% and 15% compared to IEEE 802.15.4 and IEEE 802.11 MAC protocols respectively.</p&gt;}, journal={UTEHY Journal of Science and Technology}, author={Nguyen Duy Tan and Nguyen Thi Thanh Hue and Vu Thi Thu Huong}, year={2019}, month={Oct.}, pages={39-45} }
