Abstract


With the advances in information technology, the Yunnan border construction from traditional means of efficient ways toward information technology changes, equipment renewal demand. The high cost of wired video surveillance facilities, erection difficulties, and monitor performance is not ideal because of the complexity of the natural and geographical environment, put a small amount of some folk channel can not be effectively managed. \To develop a new model to build wireless control of the border of the self-monitoring system has become an important task. And the integration of the sensor, embedded computing, modern network, wireless communication, distributed information processing technologies such as wireless sensor networks deployed due to its low price, convenience, and show a broad application prospects in the field of real-time monitoring, to address this topic with to the opportunity. Wireless sensor network technology for the border information monitoring its unique advantage. All sensor nodes to form a network through the self-organizing manner and variety of built-in aid of the node within the coverage area of ??the sensor detects infrared, pressure, sound, vibration and other signals, easy to deploy, and without cable infrastructure; sensor node The low cost of application, densely deployed long border line, easy to obtain more accurate border dynamic spatial correlation of each node to collect information. In addition, wireless sensor networks, energy efficient and meet the requirements of perennial continuous monitoring. The paper attempts to satellite positioning system based on the integration of ZigBee wireless sensor network, the construction of a high degree of information, efficient border dynamic monitoring system. The main research work includes: ① proposed border information to monitor the use of satellite communications network, using a heterogeneous cluster network structure and design of high-performance the wake of nodes based on the rotation and the demand mode; hard ② sensor node software Design. Selected RF chip CC2430, and with the low-power microprocessor, support a variety of different sensors collaborative monitoring; ③ designed satellite sensor network positioning mechanism, the breadth of the distribution of the beacon nodes rely on satellite positioning module (or manual calibration), then using a multiple coverage based triangle centroid positioning strategy (MOTCLS), thus achieving the correct positioning of the other nodes in the network. ④ design an energy-aware and location of Adaptive Routing Protocol (ELRP), the cluster head election process integrated node residual energy and location information, adaptive routing support mobile Sink node to complete the data collection.
