基于多质心算法的无线网络的森林火灾定位技术

Forest Fire Location Based on RSSI-Multi-Centroid Algorithm

针对森林防火定位技术研究的需求,提出了一种基于多质心算法的森林火灾定位方法,称为0.618RSSIMC算法。按照森林火灾定位对信息采集的要求,RSSI定位算法和质心算法定位精度不高,APIT算法需要未知节点初始位置的问题等,而0.618RSSIMC算法先通过接收信号强度指示(RSSI)算法对未知无线传感器节点进行初始定位,再利用APIT算法和质心算法对未知节点做进一步的精化定位,并融合0.618算法优选空间节点坐标。实验仿真结果表明:融合0.618优选法的多质心算法(0.618RSSIMC)是一种有效精确定位的算法。

We proposed a forest fire location method based on 0.618 muhiple centroid algorithm, 0.618 RSSIMC （ RSSI-Multi- Centroid） algorithm, to solve problems of low position precision of RSSI algorithm and centroid algorithm, and initial position of unknown nodes in APIT algorithm. The unknown nodes first initial positioned by RSSI algorithm and then further refined by APIT algorithm and centroid algorithm. The algorithm based on 0. 618 algorithm was verified its effectiveness through the simulation test and fusion with 0.618 algorithm for further optimizing the node coordinates. Threrfore, 0.615 RSSI-Muhi-Centroid Algorithm is an effective algorithm with high position precision.
