摘要:

无线传感器网络(WSNs)由许多低成本、轻量级传感器分散在区域内以监测物理环境。WSN区域中的事件检测,尤其是同时检测多个事件,是一个重要的问题。本文尝试基于分布式数据处理结构和贝叶斯准则进行双事件检测。为准确检测两个同时发生的事件,我们提出了基于似然比检验的新决策规则,并基于贝叶斯准则推导了检测错误概率。除了多事件检测外,所提出的方法还扩展为容错过程,以应对传感器决策中的故障。所提出方法的性能在不同情况下进行了验证。结果表明该算法在容错多事件检测中具有有效性。

英文摘要:

Wireless Sensor Networks (WSNs) consist of many low cost and light sensors dispersed in an area to monitor the physical environment. Event detection in WSN area, especially detection of multi-events at the same time, is an important problem. This article is a new attempt for detection of two simultaneous events based on distributed data processing structure and Bayesian criteria. For accurate detection of two simultaneous events, we proposed new decision rules based on likelihood ratio test and also derived probability of detection error based on Bayesian criteria. In addition to multi-event detection, the proposed method is expanded to a fault-tolerant procedure if there are faults in decision making of sensors. Performance of the proposed approach is demonstrated for detection of events in different circumstances. Results show the effectiveness of the algorithm for fault-tolerant multi-event detection.
