Method for transmitting data among clusters of wireless sensor network

Abstract

The invention relates to a method for transmitting data among clusters of a wireless sensor network, and belongs to the field of real-time embedding. An ant colony algorithm has the characteristics ofdistribution, positive feedback and the like, and is suitable for solving the problem of combination optimization. The method comprises the following steps: firstly, initializing an ant colony, thenconsidering factors which may influence a network life cycle, further formulating a fitness function, and formulating a new state transition probability calculation formula in combination with an original classical ant colony algorithm; calculating the state transition probability value of each cluster head, judging the cluster head of the next hop, updating the local pheromone in the single iteration process, and finding out a complete traversal path according to the method; then carrying out pheromone updating on each path, subtracting the energy consumption balance factor from the ratio ofthe minimum residual energy to the maximum residual energy in the path , and fusing the difference into an updating rule to control the increase and decrease of the pheromones. The corresponding relations between the cluster head and the ant colony node are established, energy conservation and energy consumption balance are fully achieved, and the life cycle of an incoming network is effectivelyprolonged.

Description

technical field [0001] The invention relates to a data transmission method between wireless sensor network clusters, and belongs to the field of real-time embedded technology. Background technique [0002] The cyber-physical fusion system has been widely used in real life in recent years. It perceives and acquires data through a wireless sensor network composed of a collection of sensors that are distributed in the sensing environment, and transmits it to the observer through a certain routing method. Its purpose is to cooperatively perceive, collect, process and transmit information of perceived objects in the geographical area covered by the network. Since most of the environments that need to be sensed are relatively harsh, and the sensors are provided by micro batteries embedded in them, once the battery energy Exhaustion will cause the node to fail. It is very difficult to precisely locate and replace new sensor nodes. Contents of the invention [0003] The inventio...
