捕获效应下的泛用混合查询树防碰撞协议

在射频识别系统中，无论是查询树协议还是改进型的混合查询树协议，都是在不考虑捕获效应的基础上使得在阅读器范围内的标签全部识别。借鉴泛用查询树协议的思想，对改进型混合查询树协议进行改造并提出泛用混合查询树协议。该协议能在捕获效应的环境中同样获得完全的识别率，比泛用查询树协议更快速。仿真实验表明该协议的有效性。

Generalized Hybrid Query Tree protocol for coping with capture effect

Both of Query Tree protoco（lQT）and Improved Hybrid Query Tree（IHQT）can identify all of the tags in the broadcast range of a reader without the capture effect in the Radio Frequency Identification（RFID）system.This paper proposes the Generalized Hybrid Query Tree（GHQT）by improving the IHQT with the idea of the Generalized Query Tree（GQT）.The protocol can identify all tags even if considering the capture effect and is faster than GQT.The simulation performance shows the protocol is effective.
