Wireless sensor network topology control method based on artificial neural network (ANN)

Abstract

The invention provides a wireless sensor network topology control method based on an artificial neural network (ANN). The method is characterized in that the aim of saving energy is achieved by simulating an information processing system of a biological neutral network; when the total vector of the signals input by senor nodes is more than the threshold of a neurone, the neurone is activated and gives out pulses, thus outputting the signals; the nodes are selected to become the cluster heads according to the output signals and the dump energy to primarily form a network topology map; other nodes select the nearest cluster heads and join in the clusters and transfer own information to the cluster heads; the network topology map is optimized in combination with power control; and the transmitting power of the cluster heads is controlled so as to balance the number of the sensor nodes covered by the network, thus reducing collision during communication and improving the communication efficiency. The method has the following beneficial effects: under the condition of ensuring the network connectivity and coverage, the network energy is reasonably and efficiently used as far as possible, the life time of the whole network is lengthened and the nodes in each cluster are balanced to reduce communication interference among the nodes and improve the network communication efficiency.

Description

technical field [0001] The invention relates to a neuron-based wireless sensor network topology control method, which is mainly used to reduce energy consumption of sensor nodes and improve communication capabilities, and belongs to the application fields of neuroscience, thinking science, artificial intelligence, and distributed computing. Background technique [0002] The wireless sensor network is a multi-hop self-organizing network system formed by a large number of cheap micro sensor nodes deployed in the monitoring area through wireless communication. , and sent to the observer. Sensor nodes are tiny and often carry batteries with very limited power. Due to the large number of sensor nodes, low cost requirements, wide distribution area, and complex deployment area environment, some areas are even inaccessible to personnel, so it is unrealistic to supplement energy by replacing batteries.
