The reliability of data transmission and the energy consumption of wireless nodes in wireless sensor networks (WSNs) are important issues as interest in this type of network increases. IEEE 802.15.4 is a suitable protocol for WSNs because it was designed for low-power operation via wireless communications. The guaranteed time slot (GTS) of IEEE 802.15.4 can usually be used for cyclic data transmission. However, an unused GTS allocation wastes energy. This paper suggests an energy-efficient IEEE… CONTINUE READING
