Restructing 802.15.4 MAC protocol's Superframe structure for energy and transmission efficiency
Dahae Jung, Jinoo Joung, Hanjin Cho · 2015
Recently Internet of Things(IoT) technology, especially the technologies used for Wireless Sensor Network (WSN) have attracted great amount of attention. Since ZigBee, which is a low-power and low cost technology, is appeared, related applications are proliferation. The studies of how energy efficiency can be further achieved are steadily on progress. In this paper, we propose a method which increases the energy efficiency by reducing unnecessary Clear Channel Assessment(CCA) and by increasing the sleep duration of End-Device through changing the structure of a ZigBee Superframe using the IEEE 802.15.4 Medium Access Control(MAC). Simulation results show that our method increases energy efficiency.
