Problems solved by technology

Some existing methods for data transmission routing methods tend to fall into local optimum, and the search method is complicated, which makes the energy consumption of sensor nodes in the distribution network too much, and it is easy to cause routing holes, resulting in intelligent distribution networks. The efficiency of data collection and transmission in the power grid is reduced, and the effect is not ideal

Embodiment Construction

[0035] The invention will be further explained below in conjunction with the accompanying drawings.

[0036] Such as figure 1 As shown, a smart distribution network WSNs routing method of an ant colony algorithm fused with membrane computing includes the following steps:

[0037] Step 1: Initialize the initial node energy E in the network 0 , initial pheromone concentration τ ij (t), the distance between nodes d ij and environmental information;

[0038] Step 2: Initialize the membrane structure in membrane calculation as [ 1 [ 2 ] 2 [ 3 ] 3 [ 4 ] 4 ] 1 , membrane 1 is the main membrane; membranes 2, 3, and 4 are sub-membranes;

[0039] Step 3: Before the algorithm starts to iterate, place n ants at the initial node in each sub-membrane to prepare for routing path selection;

[0040] Step 4: After the preparation work is completed, in each sub-film, the ants on the initial node are calculated according to the probability Select the next hop node to construct the...

Abstract

The invention discloses a power distribution network WSNs routing method integrating membrane calculation and ant colony algorithm improvement. According to the method, while a traditional ant colonyalgorithm is improved, membrane calculation is introduced to optimize the algorithm. A dynamic compensation factor is introduced into a state transition function, so that the phenomenon of premature stagnation of the algorithm due to too high pheromone is avoided. The parallel capability of intra-membrane operation and inter-membrane operation is calculated by using a membrane, and an introduced optimal path measurement formula is combined to carry out multi-path parallel search to obtain an optimal path, so that the local and global convergence capability of the algorithm is improved. By defining a routing repair mechanism, routing holes are avoided by the algorithm. According to the method, the search complexity is avoided, the search speed is increased, the reliable routing of the datais obviously enhanced, the energy-saving requirement is met, and the service life of the network is prolonged.

Description

technical field [0001] The invention relates to the field of data transmission in intelligent distribution network WSNs, in particular to a data routing method of fusion membrane calculation and ant colony algorithm. Background technique [0002] As the country put forward the concept of "smart grid", the national grid began to transform from the traditional grid to the smart grid. The advantages of the smart grid can be detected online through smart devices, which greatly enhances the security and stability of the grid, and the wireless sensor network can conveniently and quickly collect the information and operation data of the power distribution gateway equipment to achieve real-time monitoring, so the wireless The introduction of sensor networks into the smart distribution network has obvious advantages. However, since the wireless sensor network is composed of a large number of sensors, the energy of its nodes depends on its limited storage energy. Once installed and d...
