Research On Data Collection Algorithm Based On WSN In Mountain Environment

Since China's mountainous terrain has a complex environment,many geographical environments have a series of environmental features such as treacherous terrain,blocked communications,and frequent natural disasters.Guizhou is a typical mountainous province,accounting for 92.5% of the total land area of the province and hill slopes.Steep terrain and complex terrain make it difficult for many jobs to be carried out through human resources.This is particularly true in terms of data collection and communication.In a geographical environment where many mobile phone signals are not available,the most important thing is that how to ensure that data can be reliably and successfully collected.Wireless sensor network(WSN)is a multi-hop self-organizing network that monitors the monitoring area by assigning sensor nodes.With the popularization of intelligent sensor nodes,the functions of wireless sensor networks are gradually improved.In order to be able to in the complex mountainous environment to reliable and efficient data collection and transmission,you need to analyze the performance of WSN channel,through the analysis of the results to the mountain environment data acquisition of routing algorithm for rational planning and design.This article mainly studies from the following three aspects.Firstly,analysis of wireless signals of different frequency band(433 MHz,868 MHz,915 MHz,2.4 GHz frequency band four wireless signals),the characteristics of field test,compare the test data,a Zig Bee network as the data can be used in the mountain environment monitoring in wireless sensor networks;The second was Analyze the data measured in three mountain environments,process the data through least square fitting,and complete the channel modeling analysis of Zigbee network;Finally,with the help of the analysis results of channel model of mountain environment planning data acquisition routing algorithm,and through computer simulation,the rationality of the planning of the routing algorithm is verified by of mountain environment of wireless sensor network datacollection theory research of the algorithm.
