在本文中，我们解决的问题，跟踪对象与网络的无源标签，相互通信的基础上，反向散射的原则。标签是RF供电的，并且能够被动地反射外部RF信号。在反射信号的同时，它们也对信号进行调制，从而传输信息。基于它们从邻居那里接收到的信号的特征，标签能够检测到它们附近是否有新的物体。它们在没有绝对时间的情况下运行，并且它们在任何意义上都不同步。我们提出了一种用于检测对象的方法，一种用于在向数据处理中心报告对象的存在的同时在标签之间进行通信的协议，以及一种用于基于从标签接收到的信息来估计对象的轨迹的方法。
In this paper, we address the problem of tracking objects with a network of passive tags that communicate with each other based on the principle of backscattering. The tags are RF powered and are able to passively reflect an external RF signal. While reflecting the signal, they also modulate it and thereby they transmit information. Based on the features of the signals they receive from their neighbors, the tags are capable of detecting if there is a new object in their proximity. They operate without access to absolute time, and they are not synchronized in any sense. We propose an approach for detecting an object, a protocol for communication among the tags while reporting the presence of the object to a center for data processing, and a method for estimating the trajectory of the object based on the received information from the tags.
