摘要: | Zigbee 是一个低成本、低功耗的无线通讯技术,可以广泛的应用在消费性电子的无线感测器网路中。在无线网路中,资料遗失是不可避免、没有规律、也无法预测的。因此为了在室内环境建构出可靠的Zigbee无线感测器网路,讯号传输的分析与资料遗失的补偿是相当重要的。在本论文中,将距离及墙壁等复杂的环境因素纳入考量后,透过实验获得了讯号传输模型。此外发展出一套可以监视Zigbee无线感测器网路中各个节点状态的电脑图形介面(CGI),且提出整合intelligent message estimator(IME)与combined message design(CMD)的架构并应用到Zigbee网路的传输中,成功降低了资料遗失率。 ZigBee is a low-cost and low-power, wireless communications technology that can be used widely in the wireless sensor network (WSN) for consumer electronics. It is crucial to construct monitoring systems via the ZigBee WSN by applying signal propagation analysis and data dropout compensation to improve their reliability, especially in the indoor environment. Furthermore, the data dropout is also unavoidable, irregular, and unpredictable in nature. In this thesis, the propagation model is thus obtained through experiments in complex environments where the distance and the wall effect are taken into consideration. A computer graphics interface (CGI) system has been developed for monitoring each node status of the ZigBee WSN. In present study, experimental results indicate that the intelligent message estimator (IME) integrated with proposed the combined message design (CMD) has been applied to ZigBee transmission to successfully estimate the dropout data. Keywords: Propagation, monitoring application, data dropout |
