RSSI-based location is a hotspot in nowadays. This paper presents RSSI-based triangle and centroid location algorithm and trilateration algorithm, and analyses the average positioning error produced by this two methods. Simulation experiments prove that triangle and centroid location algorithm can obviously improve the location accuracy compared to trilateration algorithm.

node location is one of the key technologies in wireless sensor network.rssi－based location is a hotspot in nowadays.for resolving biggish error in rssi－based location,the paper presents a new method of location,rssi－based triangle and centroid location,using triangle and centroid method to reduce the error of rssi measurement.simulation experiments prove that this algorithm can obviously improve the location accuracy compared to trilateration.

摘 要：节点定位是无线传感器网络中的关键技术之一。基于rssi的定位技术是现阶段研究的热点，为解决rssi测量方法定位误差较大的问题，提出一种将rssi测量方法与三角形质心算法相结合的新型定位算法，该算法用三角形质心算法减小rssi的测量误差。仿真表明该算法比基于rssi的三边测量法定位算法的定位精度有较大提高。

From the earliest known for the IFP-100 series, iRiver and proves that his great strength, from out of the sound quality of MP3 no good argument, the iron triangle design enjoys popular support and become classics; after the IFP-300, IFP - 700, IFP-800 continuation of the iron triangle of brilliant, but also the achievement of high-quality high-end Philips chip status, although later experienced core for the short-term decadence, T series or have been successful, also shows that the style and sound Aere The shift, and the recently introduced T50, T60 also for the excellent cost-effective, access to a lot of warm FANS sought after, a gorgeous high-end color of CLIX, the attractive, compact S10, S7, the beautiful people爱不释手Guaiqiao Mplayer and so on. Aere dynasty and show that the overall boom!
