Research On The Routing Protocol Of Meteorological Observation System Based On CTP

As the global climate is becoming warmer, there are more and more extreme weather events. The traditional automated meteorological observation system cannot meet the demand of the society fully. In this paper, the wireless sensor network is introduced to the meteorological observation system, which is a supplement to it.In the meteorological observation system based on wireless sensor network, the research on network routing protocol is a core issue. After analyzing and studying the Collection Tree Protocol, we proposed the congestion detection and congestion control strategy and the security mechanism based on data hiding technology, then we completed the design of the routing protocol which can meet the demand of the system.The main contents and results of this paper are as follows:(1) Make a research and summarize to the study of the wireless sensor network, and analyzing the advantages and disadvantages of it. Then introduce wireless sensor network to the meteorological observation system to make up the deficiency of meteorological observation system.(2) We research the wireless sensor network routing protocol from several aspects and analyze the strengths and weaknesses of various routing protocols. And we focus on Collection Tree protocol and finally choose it as the protocol of the meteorological observation system.(3) By analyzing the congestion phenomenon in the wireless sensor network, we proposed congestion detection and congestion control strategy. And the strategy can effectively solve the congestion problem and ensure the stability of the sensor network.(4) We presented a false identity attack detection scheme based on data hiding technology. The scheme can find the attackers effectively without affecting the transmission and use of the packets in the network.
