摘要: 为使高密度的无线异构传感器网络能够有效地进行复合事件检测,提出一种基于支配集的复合事件检测算法。寻找网络中的一个支配集作为局部决策节点集,局部决策节点进行局部决策以判断复合事件是否在决策范围内发生。仿真结果表明,与传统的CollECT算法、CDS算法相比,该算法能提高检测精度,减少网络的能量消耗。

Abstract: To detect a composite event efficiently in Wireless Heterogeneous Sensor Networks(WHSN) which has huge amounts of variant wireless sensor nodes, this paper proposes an algorithm to detect composite events based on the concept of Dominating Set(DS). It looks for a dominating set in the network as the set of local decision nodes. Local decision nodes make local decisions about composite events within a radius of local decision. Simulation results show that the algorithm improves the accuracy of detection, reduces the consumption of energy compared with existed Collaborative Event detection and Tracking(CollECT) algorithm and Connected Dominating Set(CDS) algorithm.
