Dynamic wireless sensor and actor networks event driven localization algorithm

动态无线传感器反应网络(WSANs)是传统无线传感器网络(WSNs)的衍生物,是由大量资源受限的传感器节点和少量资源不受限的反应节点组成的动态网络,采用无线通信的方式进行通信,具有很强的实用性和应用前景。在充分分析动态WSNs特点的基础上,提出了一种基于接收信号强度指示(RSSI)测距的分布式事件驱动定位算法,并利用OPNET网络仿真软件对所设计的算法进行了仿真验证,结果表明:所设计算法具有较高的定位精度和能效性。

Dynamic wireless sensor and actor networks（DWSANs） are composed of a large number of resourcelimited sensor nodes and a small number of resource unlimited reactive sensor nodes,which is the derivatives from traditional wireless sensor networks （WSNs）. It has very strong practicality and perspective. On the basis of analysis of characteristics of dynamic wireless sensor and actor networks ,an event driven localization scheme based on the RSSI range measuring is proposed. The localization algorithm is simulated using OPNET network simulation software, the result proves that the localization algorithm has the feature of higher accuracy and energy efficient.
