Abstract

The Radio Frequency Identification (RFID) system has become one of the most popular systems for identifying and tracking the objects. ZigBee enabled RFID interrogator mesh network has been formed for tracking person or object. The paper presents investigation of different scenarios of tag movement pattern to find out the virtual path in the RFID interrogator mesh network. When transponder enters into the intersecting zone then, all the two interrogators will interrogate it at different time slot. Therefore, two tracking dataset will be independently generated containing different timestamps. However, only one interrogator and its corresponding tracking dataset shall remain in the database. The deduction of this knowledge will be based on the position of the previous and the next interrogator of these two interrogators along the track. In this case, we have created a virtual interrogator at the mid point area Y to indicate the intersecting interrogation. This paper proposes the architecture and Virtual Route Tracking (VRT) algorithm for tracking objects in the ZigBee enabled RFID interrogator mesh Network.

虚拟路由跟踪在ZigBee (IEEE 802.15.4)启用RFID询问器网状网络

无线射频识别(RFID)系统已成为最流行的识别和跟踪物体的系统之一。已形成支持ZigBee的RFID询问器网状网络，用于跟踪人或物体。本文研究了RFID查询器网状网络中不同场景下标签运动模式的虚拟路径。当应答器进入相交区域时，两台应答器将在不同的时隙对应答器进行应答。因此，将独立生成两个包含不同时间戳的跟踪数据集。但是，数据库中只应保留一个询问器及其相应的跟踪数据集。这一知识的推导将基于这两个询问者在轨道上的前一个和下一个询问者的位置。在本例中，我们在中点区域Y创建了一个虚拟询问器，以指示交叉询问器。本文提出了一种基于ZigBee的RFID询问器网状网络的结构和虚拟路由跟踪(VRT)算法。
