数据发送为主的LPWA网络传感器节点MAC协议设计
发布时间：2023-07-24 22:00
在不断发展的技术中,满足这个智能世界的需求有许多属性和挑战。一些挑战包括低功耗,低成本,低比特率,高安全性,可靠性,高性能和吞吐量,能耗等。自上几年以来,许多技术已经出现,旨在克服上述挑战。已经引入了一种称为LPWAN-低功率广域网的无线电技术,其用于不同IoT应用和M2M中的无线数据通信。具有仅传输节点的网络由于其在以低成本和低能耗的长期部署中的优势而吸引更多。仅传输具有缺少接收器的缺点的节点,使得大多数现有MAC协议无效。以前的许多研究都集中在纯传输节点上,这些节点具有一些优点和缺点。在仅传输节点的情况下,不能接收接收器数据确认。这使得学者们专注于传输主要节点,这些节点确认云/服务器上成功的数据包接收。但是在传感器中加入接收器也有许多缺点,例如增加,功率成本,系统成本和延迟等。考虑到所有这些,一些研究集中在仅传输节点打开接收模块以在预定时间内转换为公共节点当服务器可以分发配置命令等时,只持续很短的时间。我也把它带到了我的研究中。为了提高PDR(数据包传输率)并减少接收信号的延迟,我的论文提出了一种CRDSA MAC协议设计。有许多MAC协议有助于避免冲突并提供更好的PDR和吞吐量结...
