Zigbee Protocol

<p><span style="font-size: medium;"><span style="font-family: 宋体;">In wireless sensor networks, for improving the time synchronization perfromance of online monitoring and application of ZigBee protocol, a scheme is designed. For this objective, first of all, the ZigBee protocol specification is summarized, a profound analysis of the hardware abstraction architecture of TinyOS operating system is made; the advantages of the ZigBee protocol compared with the traditional radio technology are comparatively analyzed. At the same time, the node design block diagram based on CC2430 and related development system is provided. In the TinyOS2.x operating system, we analyze CC2430 application program abstract architecture, and on this basis, give the realization process of program design. The research results showed that we achieve an on-line monitoring system based on ZigBee protocol, which has realistic significance of applying ZigBee protocol in wireless sensor network of electrical equipment online monitoring. Based on the above research, it is concluded that the online monitoring system can collect the temperature parameters of the monitored object in real time that it can be widely applied in wireless sensor networks.</span></span></p>

A SSNS (simple sensor network sniffer) is used to analyze and evaluate the Wireless Sensor Networks (WSN) effectively. SSNS is designed to monitor IEEE 802.15.4 protocol frame, which based on the Ethernet. Unlike the existed monitoring system, our design is much simpler and needs less resource. It is analyzed in this paper that the monitor network framework, time synchronization, and analysis program design. The results show that SSNS works stably, and can real-time display the frame monitored and reflect the dynamic change of WSN.

Secure Localization

<p class="0abstract"><span lang="EN-US">In order to study the intelligent buildings, the intelligent building network security of wireless sensor was explored. Because of its advantages of low cost, easy installation, low maintenance and update cost, wireless sensor network system was applied to intelligent building. In view of the characteristics of various influencing factors on the wireless sensor network working environment, node hardware cost and location accuracy, a secure localization algorithm based on DV-Hop was put forward. The security analysis results showed that the algorithm resisted external attacks and guaranteed the accuracy of location results. Based on the above findings, it is concluded that the algorithm can be used to protect the safety of wireless sensor network in building. </span></p>
