Research On Routing Algorithm Of Wireless Sensor Networks Based On Compressed Sensing

As a comprehensive network of multi-domain interaction,wireless sensor networks are jointly maintained by many technologies.Data compression and routing design are key technologies to support their stable operation,which directly determines the energy efficiency and life cycle of the overall network.At present,the design of routing algorithms based on compressed sensing has become a hot research topic.The introduction of compressed sensing technology in routing algorithms can effectively reduce the amount of data transmission and improve the energy efficiency of the network.The paper studies the routing algorithm based on compressed sensing to solve the problems of complex algorithm of compressed sensing technology and unreasonable routing algorithm design in the current research.The main research contents and work results of the thesis are as follows:(1)Firstly,aiming at the complex algorithm of compressed sensing technology,the paper adapts a compressed sensing data acquisition algorithm based on spatiotemporal correlation under clustering structure.The algorithm does not change the network structure,and only compresses the cluster head data,which reduces the application threshold of the compressed sensing technology.The simulation results show that the algorithm can effectively reduce the total amount of data transmission and improve the energy efficiency of the network under the premise of ensuring the accuracy of reconstruction.(2)Secondly,for the problem of unreasonable cluster head distribution and low energy efficiency in the design of uniform clustering routing algorithm,an improved uniform clustering routing algorithm is proposed.Based on the original algorithm,the algorithm establishes double threshold and edge degree to optimize the network load;improve the clustering mechanism to reduce energy consumption.The simulation results show that the improved life cycle is significantly improved and the network load is more balanced in the large and small area environment.(3)Finally,for the problem that the cluster size is difficult to control and the multi-hop selection is not optimized enough for the non-uniform clustering routing algorithm design,a non-uniform clustering routing algorithm is proposed.The algorithm sets up a dual cluster head and odd-even wheel mechanism to improve the competitive radius formula and optimize multi-hop selection.The simulation results show that the cluster size of the algorithm is reasonable,the energy consumption of multi-hop transmission is reduced,and the network is more stable.
