摘要:

无线传感器网络主要用于采集数据和处理数据,因此被广泛应用于多个领域。然而,网络中大多数由电池供电的传感器节点体积较小,导致其无法长时间工作,所以设计了一种能够有效提高能源利用率、降低网络通信能耗的分簇方法。分簇方法是无线传感器网络的重要研究方向之一。针对传统分簇方法选出的簇头节点方案存在的通信能耗较高问题,提出了一种基于克隆精英遗传算法的无线传感器网络能量高效分簇方法。在进行分簇时,利用克隆精英遗传算法在监测范围内选择部分传感器节点作为簇头节点,进而对网络通信能耗进行优化。在迭代过程中,克隆算子和精英算子将能耗小的簇头节点方案尽可能保留下来,减少了运行时间,同时也增大了获得较优簇头节点方案的可能性。把所提方法与基于精英遗传算法的分簇方法、基于蛙跳算法的分簇方法进行了仿真比较。仿真结果表明,基于克隆精英遗传算法的分簇方法与另外两种方法相比显著地降低了网络通信能耗,提高了能量利用效率,有效地延长了网络寿命。

Abstract:

The wireless sensor network (WSN) is mainly used to collect and process data,so it is widely used in many fields.However,most battery-powered sensor nodes in the WSN are small in size,which makes them unable to work for a long time.Therefore,designing a clustering method that can effectively improve energy utilization and reduce network communication energy consumption is one of the important research directions of the WSN.Aiming at the problem of high communication energy consumption of the cluster head node selected by the traditional clustering method,an energy-efficient clustering method based on the clone elite genetic algorithm for the WSN is proposed.In clustering,the clone elite genetic algorithm is used to select some sensor nodes as cluster head nodes in the monitoring range,and then the network communication energy consumption is optimized.In the iterative process,the cluster head node scheme with low energy consumption is retained as much as possible through the clone operator and the elite operator.The method reduces the running time and increases the possibility of obtaining a better cluster head node scheme.The proposed method is compared with the clustering method based on the elite genetic algorithm and the clustering method based on the shuffled frog leaping algorithm.Simulation results show that compared with the two other methods,the clustering method based on the clone elite genetic algorithm significantly reduces the network communication energy consumption,improves the energy utilization efficiency,and effectively prolongs the network life.

Key words: wireless sensor networks, clustering, genetic algorithm, shuffled frog leaping algorithm
