technical field [0001] The invention relates to a method for improving the routing transmission quality of a sensor network, in particular to a method for improving the routing transmission quality of a wireless distributed sensor network, and belongs to the technical field of routing transmission of a sensor network. Background technique [0002] The sensor network has developed rapidly since the development of the Internet and the Internet of Things, and has gradually played an increasingly important role. The wireless distributed sensor network is an important part of the sensor network. It is mainly composed of many sensor nodes. These micro-nodes communicate with each other by transmitting wireless network signals and comprehensively analyze various information.

The sensors transmit the change information to the center at the fastest speed according t...

AI Technical Summary

Problems solved by technology

[0009] One is that the routing transmission algorithm of the existing wireless distributed sensor network only considers a certain factor of the routing transmission quality, and it is inaccurate to use only one of the various routing transmission quality parameters as a standard to judge the quality of the selected path. , the existing technology does not comprehensively consider the factors of node energy, link delay, packet loss rate and available sensor network bandwidth, and does not integrate their values ​​into a numerical value in the form of a function to judge the quality of a certain path, only considering A certain factor of routing transmission quality has obvious subjectivity and one-sidedness, and the algorithm designed and improved based on this are obviously unreliable

[0010] Second, the existing technology does not consider the energy factor

Due to the small size of the micro-sensors that make up the wireless distributed sensor network, they can only store a small amount of energy and cannot meet the long-term use of the network. Therefore, it is necessary to consider the energy factor of the sensor nodes, and try to maintain the energy balance of the entire network nodes to avoid The problem of premature loss of some key nodes due to energy depletion, but the existing technology does not consider this, it is easy to deplete the energy of sensor nodes, so that some key nodes are prematurely lost due to energy depletion, which seriously affects the entire network. operating hours

[0011] The third is that the existing technology does not fully apply the idea of ​​the bird flock foraging algorithm to the routing transmission algorithm to find the best path, the routing transmission algorithm has poor feasibility and reliability, and the algorithm has the problems of slow path convergence and falling into a local optimal solution. Technical schemes have too slow convergence speed, low security, too rigid models, too many problems in actual application, poor flexibility, poor robustness, and cannot be well extended to wireless distributed sensor network routing transmission applications
