摘要
在开展大规模区域数据采集的无线传感网中,由于相邻区域数据的相似性造成的冗余会使得传感器能量耗费过多而过早死亡.针对该问题,提出一种基于区域生长法的WSN数据采集算法(DAA-RGM),该算法划分传感器网络部署区域,划分后根据子区域采集的历史数据选择一个与该子区域的历史数据变化趋势相似性最高的节点为代表节点.上述方法能够保证区域监测正常的情况下减少大量的冗余数据,因此能够较大幅度的延长传感器网络的生存时间,实验结果验证了该算法的有效性和可靠性.
WSN is widely applied in data acquisition in a large-scale region. For the similarity of data in adjacent regions,the nodes will acquire a large amount of redundant data which easily cause the network failure for large consumption of energy. To solve this problem,we propose an improved data acquisition algorithm based on region growing method that called DAA-GGM. The algorithm firstly acquires the whole networks data,and set part of nodes as seed randomly. Then it uses region growing method to divide the deployment area into many subareas where representative nodes which is most similar to the trends of the historical data will be chosen.The result of simulation shows that the proposed method of this paper can effectively reduce a lot of redundant data and prolong the network's survival time on the normal circumstance in the monitoring area.
