摘　　要：低功率广域网(LPWAN)技术正在兴起,可以使无线通信达到很长的距离。LPWAN设备通常直接与汇聚节点通信,这样就不需要构建和维护复杂的多跳网络。然而,为了保证高效可靠的通信,LPWAN设备往往提供大量的传输参数。如何在满足通信性能要求的同时,将传输能量成本降到最低,这是一个挑战。本文对通信性能受通信参数选择的影响进行了分析。Low power wide area network(LPWAN)technology is emerging,which enables wireless communication over long distances.LPWAN devices usually communicate directly with sink nodes,so there is no need to build and maintain complex multi-hop networks.However,to ensure efficient and reliable communication,LPWAN devices often provide a large number of transmission parameters.It is a challenge to meet the requirements of communication performance while minimizing the cost of transmission energy.The influence of communication parameters on communication performance is analyzed in this paper.
