Task scheduling method for wireless sensor grid based on energy and communication overhead

The invention discloses a task scheduling method for a wireless sensor grid based on energy and communication overhead and belongs to the technical field of communication. In the method disclosed by the invention, the task scheduling method of the wireless sensor grid is divided into the data acquisition stage of the wireless sensor grid and the data analysis and computation stage in the grid; a mode matching method based on pixel nerves is used in the wireless sensor grid, thereby reducing the computation task of nodes in the wireless sensor grid, effectively reducing the energy consumption of tasks such as node environment perception, data transmission, computation and the like, saving the energy of a power supply and prolonging the service life of the nodes; a genetic algorithm based on a duplication strategy is adopted in the grid; and according to the priority of a key task, the strategy of operation duplication is adopted, thereby effectively reducing the communication overhead among tasks and realizing
