摘要:
 在无线传感器网络( Wireless Sensor Network,WSN)中,传感器节点的能源有限且不能充电,因此能源效率一直是当前研究的热点和难点。数据聚集能够消除冗余数据,提高能源效率。由于自适应数据聚集算法( Adaptive Data Aggrega-tion,ADA)只适合于单跳网络,在此基础上提出通过网络编码将其应用在多跳网络中。进行网络编码的节点,距离簇头节点只有一跳的距离,这些节点根据数据相关性选择网络编码或传统的聚集算法,并且能够在未知的网络分布下,自适应调节相关性阈值。实验结果表明,该方法能够在任何初始状态下收敛到期望的可靠状态。
Abstract:
 Energy efficiency has long been a research hotspot and difficulty in WSN ( Wireless Sensor Networks) because of the limited and unrechargeable energy provision of sensor nodes. Data aggregation can eliminate data redundancy to improve energy efficiency. Since ADA ( Adaptive Data Aggregation) algorithm works only on single-hop networks,a novel algorithm is proposed by means of network coding will adapt ADA for multi-hop networks. The network coding nodes are one-hop away from the cluster head,and they take aggre-gation strategy according to data correlation,and the aggregation threshold can be adaptively adjusted in unknown networks. Experimental results show that the proposed algorithm can make the data converge to desired reliability from any initial state.
