Abstract(in English) | Low Power Wide Area (LPWA) is a novel communication technology for realizing Internet of Things (IoT) networks, and Long Range Wide Area Network (LoRaWAN) is a major research target in LPWA. LoRaWAN is capable of dynamically changing the data rate and transmission power of nodes in order to improve the packet delivery rate and achieve energy saving. However due to the low transmission speed of LoRaWAN, it is difficult to grasp the network condition by collecting information from each node, calculate the optimal data rate and assign it to each node. In this paper, we propose a spreading factor allocation method inspired by the evolutionary mechanism of living organisms that simultaneously improves packet delivery rate and energy saving even in a fluctuating network environment. Through a computer simulation, we show that optimization of such two metrics can be achieved even in a fluctuating environment. |
