摘要:

针对现有的分簇算法因存在数据回传现象使节点在能量利用效率方面存在不足的问题,提出了一种面向数据聚集的有向分簇算法,使节点数据总是沿着接近Sink的方向传输,避免了数据回传带来的能量浪费. 仿真实验结果表明,有向分簇算法具有较高的能量利用效率,能延长传感器网络的生存周期.

关键词: 数据回传, 有向分簇, 数据聚集, 能耗

Abstract:

Clustering is an important energy-saving mechanism in sensor networks. Most existing clustering algorithms ignore the reverse-data-forwarding phenomenon suffering from limitations in energy efficiency. A directional clustering algorithm (DCA) is proposed for data aggregation in sensor networks. DCA ensures that node’s data is always transmitted towards to sink but not away from it during the whole forwarding route, so as to avoid energy waste caused by the reverse-data-forwarding phenomenon. Simulations show that DCA possesses higher energy efficiency and can prolong the lifetime of sensor networks.

Key words: reverse data forwarding, directional clustering, data aggregation, energy consumption
