摘　　要：传统的分簇算法有在数据回传现象和节点能量利用率低的缺点,为了解决这个问题,文章提出了面向数据聚集的有向分簇算法。其核心思想是使网络中所有的节点传输方向全部都沿着接近Sink的方向进行,这样就解决了传统的分簇算法存在的问题。测试结果表明,此算法大大提高了能量的利用率,同时传感器网络的生存周期也得到了延长。Traditional clustering algorithms in data return shortcomings of the phenomena and node energy utilization is low. In order to solve this problem, the paper proposes oriented data gathering to the clustering algorithm. The core idea is to make all the nodes in the network transmission direction all along the direction close to the Sink, this would resolve the problems of traditional clustering algorithms. The test results show that the algorithm greatly improve the utilization of energy, while the sensor network lifetime has also been extended.
