中文摘要：

针对射频识别定位系统中RSSI线性定位算法的边界标签定位精度低问题,提出了一种改进的算法.该算法在边缘区域布置参考标签,并在这些布置参考标签的区域采用LANDMARC算法,而其它区域仍采用RSSI线性定位算法.使用MATLAB软件对算法进行仿真,结果表明：针对边界区域的定位标签,改进的算法比RSSI线性定位算法具有更好的定位精度,提高了整体定位区域的定位准确性;与LANDMARC算法相比,改进的算法由于使用较少的参考标签,所以降低了成本并且减少了算法的运行时间,从而提高了定位系统的实时性.

英文摘要：

To solve the problem of the low location accuracy of tracking tags near the boundary of detection area in RSSI linear location algorithm of radio frequency identification location system, an improved algorithm is proposed. The algorithm operating principle is that place reference tags in the boundary of detection area and use the LANDMARC algorithm in this area, use RSSI Lirlear location algorithm in the other area. MATLAB software is used to simulate the algorithm. The simulation results show that the improved algorithm achieves a higher accuracy towards tracking tags near the boundary of detection area compared with the original algorithm, consequently improves location accuracy of the whole area; compared with the LANDMARC algorithm, the improved algorithm uses the less reference tags, so reduces the cost and the running time of the algorithm, improves the positioning system＇s real time.
