| How to reduce the relay of information-routing long-distance transmission is to reduce electricity consumption and improve wireless sensor network node key factor in life; with less input on how to achieve a broader regional management and monitoring of human and nature live in harmony important technical problems. With the wireless sensor network technology, satellite positioning of the rapid development of communication technology, we have more confidence in the use of modern scientific theories to study new practical technologies to solve difficult to resolve in the past the above-mentioned problems.China is a vast power, but is a densely populated areas and sparsely populated region domain coexistence of the country, especially in western China, six percent of the population own 57 per cent of the land. Forest fire prevention, disaster monitoring, feedback and other animal movement need to consider new technological means to be completed. Such operations have two common characteristics: First Large-volume control point, the need to deploy large information collection facilities is the long distance between the two, the need for expeditious completion of the transmission of information. Based on the positioning of the satellite communications system wireless sensor networks to achieve this type of business is the best technology, "wireless sensor networks location routing technology research" to achieve this paper is to explore the latest technology. The following key elements:1) In describing the domestic and foreign scholars on the geographical location of wireless sensor network routing satellite positioning technology and communication technology-related research based on a combination of these two technologies and to develop new wireless sensor network location routing technology NGRT (New Geographieal Routing Technology) idea. The technology includes five studies: the combination of open space in the wireless sensor network architecture; navigation satellite-based positioning of the integrated node algorithm, based on the geographical location of the Beidou satellite routing, security trust location routing algorithm, the relevant analysis of the complexity of the algorithm.2) The institute described the conduct related to the basic theory and method to test the model, including graph theory, discrete and random mathematics, optimization theory and a few of the classic algorithms, static fixed topology routing algorithm simulation model and test methods Mobile node location routing algorithm simulation model and test method of adding dynamic node / conversation from the location of discrete event simulation model.3) Put forward a new combination of open space in the wireless sensor network architecture vision. This is envisaged in the analysis of satellite positioning technology and satellite communications technology for the wireless sensor network node to determine the location and route of transmission of information derived from the impact. Is a comparison of the four characteristics of the satellite positioning showed that the application of China-led Beidou satellite systems, not only to achieve rapid location of a wireless sensor network positioning, but also two-way transmission, such as geographical coordinates of the routing information.4) In the past, analysis of the wireless sensor network node's own study of the relative positioning algorithm based on the combination of open space satellite positioning technology and genetio absolute taboo mathematical algorithm proposed GATS-LS comprehensive mathematical model and positioning algorithm, and the theory and simulation to prove that its better Performance, especially in the less time the number of nodes (when the majority of the region), the effects are particularly obvious.5) Beidou satellite based on a new type of wireless sensor networks location routing algorithm. Mainly through a variety of geographic routing protocol algorithm theory analysis, pointed out that the positioning accuracy of the routing algorithm. Based on this idea, to build a cluster node District scraps Routing and location transmission model, the first integrated cluster of two-way communication with the Beidou satellite terminal device, the first cluster and routing information to determine the coordinates transmitted by the satellite system, the district cluster Location within the node and routing information transmission by optimizing the relative position within the district cluster routing algorithm to complete. The basic ant colony algorithm using mathematical algorithms and the direction of the introduction of factors to be optimized in theory to the correctness of the algorithm and performance characteristics are analyzed, and a simulation test. This method will not only be able to correctly complete the routing, and the formation of the benefits and other similar algorithm has been compared to the maximum extent of the upgrade.6) Put forward the introduction of confidence-building mechanism for multi-path routing algorithm. To address the satellite link multi-path routing choice in the process of communication security, the algorithm describes the overall security framework, and gives confidence in the specific formula for the geographic location of wireless sensor network routing information security Provides options.
