无线传感网可靠性指标体系研究

Research on Reliability Index System of Wireless Sensor Network

为了保障无线传感网的可靠性,对无线传感网的可靠性指标体系进行了研究。首先,对无线传感网进行了分层,将无线传感网分成了感知层、传输层和应用层;然后,对每一层的结构给出了独立的可靠性考核指标,并形成了无线传感网的可靠性指标体系;最后,针对提出的每项可靠性指标均提供了定义和相应的数学表达式。利用提供的结论可以方便地对不同应用场景的无线传感网的可靠性进行考核,以检测现有网络是否达到了预期的可靠性指标。

In order to guarantee the reliability of wireless sensor network,the reliability index system of wireless sensor network is studied.Firstly,the wireless sensor network is divided into sensing layer,transmission layer and application layer.Then,an independent reliability evaluation index is given for each layer structure,and the reliability index system of wireless sensor network is formed.Finally,the definition and corresponding mathematical expression of each reliability index are provided.The results provided can be used to evaluate the reliability of wireless sensor networks in different application scenarios,so as to detect whether the existing networks have reached the expected reliability index.
