环境中和周围的传感器变得无处不在，迎来了智能动物农业时代，这有可能大大改善动物健康和生产力。从动物农业环境中的传感器收集的数据使农场成为物联网空间的一部分，从而积极研究为农场网络开发有效的通信方法。这项研究的重点是农场网络的第一跳，其中来自动物体内的数据被传送到身体外的节点。使用新的实验方法来计算在亚GHz频率（100-900 MHz）下的信道损耗，以表征大型动物体内到体外（IBOB）的通信信道。利用计算机视觉技术完成了第一个3D牛模型，用于动物身体的详细形态特征，以执行基于有限元法的电磁仿真。模拟结果经过实验验证，为IBOB动物身体通信建立了完整的通道建模方法。3D牛模型在GitHub上公开提供。结果表明，IBOB通信信道是可实现的，从瘤胃到反刍动物的衣领，路径损耗在sub-GHz频率，使通信可行。所开发的方法已用于反刍动物，但也可用于其他IBOB研究。可以使用针对动物中的IBOB通信所示的信道建模技术来形成有效的通信架构，为未来智能动物农业系统的设计和开发铺平道路。
Sensors in and around the environment becoming ubiquitous has ushered in the age of smart animal agriculture which has the potential to greatly improve animal health and productivity. The data gathered from sensors dwelling in animal agriculture settings have made farms a part of the IoT space leading to active research in developing efficient communication methodologies for farm networks. This study focuses on the first hop of farm networks where data from inside the body of animals is communicated to a node dwelling outside the body. Novel experimental methods are used to calculate the channel loss at sub-GHz frequencies (100–900 MHz) to characterize the in-body to out-of-body (IBOB) communication channel in large animals. A first-of-its-kind 3D bovine modeling is done with computer vision techniques for detailed morphological features of the animal body to perform Finite Element Method based Electromagnetic simulations. The results of the simulations are experimentally validated to build a complete channel modeling methodology for IBOB animal-body-communication. The 3D bovine model is made available publicly on GitHub. The results illustrate that an IBOB communication channel is realizable from the rumen to the collar of ruminants withpath loss at sub-GHz frequencies making communication feasible. The developed methodology has been illustrated for ruminants but can also be used for other IBOB studies. An efficient communication architecture can be formed using the channel modeling technique illustrated for IBOB communication in animals paving the way for the design and development of future smart animal agriculture systems.
