【摘要】 近年来,出现了很多基于无线传感器网络的应用系统,在需要传感器节点位置信息的无线传感器网络中,无线传感器节点的定位就显得尤为重要。由于已经开发的定位系统和定位方法各有优缺点,本文在已有的无线传感器网络定位系统和定位方法的基础上,提出了一种将RSSI和DV-Hop相结合的无线传感器网络定位算法,弥补了RSSI算法和DV-Hop算法在使用中的不足,并提出了一种改进的质心定位算法。仿真结果表明了定位精度得到了提高。更多还原

【Abstract】 In recent years, numerous application systems which are based on wireless sensor network appear. In the need of sensor node localization information to the wireless sensor network, a wireless sensor node localization is particularly important. Because of the positioning system and positioning method which have been in development have its advantages and disadvantages. This paper puts forward a wireless sensor network localization algorithm which connects RSSI with DV-Hop , the algorithm makes up the insufficiency of the RSSI algorithm and DV-Hop algorithm in use, in addition ,the paper offers an improved centroid localization algorithm, it ’s simulation results showed that the positioning precision is improved.更多还原
