Embodiment Construction

[0023] We combine animal breeding environment detection wireless sensor network models, such as figure 1 Shown, the concrete implementation of the present invention is described in detail, as figure 2 shown.

[0024] In the animal breeding environment detection area of ​​100m×100m, 100 sensor nodes are randomly arranged, and the base station is located at (50, 175)m. The specific model is:

[0025] (1) The base station is far away from the animal breeding environment sensing area;

[0026] (2) The sensor nodes are randomly distributed and the energy is limited, so they cannot be supplemented

[0027] (3) Each breeding environment detection sensor knows its own location information

[0028] (4) The sensor node has a power control function and can send power consumption according to the distance

[0029] (5) The node is stationary or moves very slowly relative to the base station

[0030] 1) Optimize clustering

[0031] The invention firstly calculates the number of optim...

Abstract

The invention discloses a wireless sensor network clustering routing method based on particle swarm optimization and ant colony optimization, and belongs to the technical field of wireless sensor networks. The method is characterized in that the method comprises the steps that the optimal cluster quantity of an animal breeding environment detection system is decided dynamically; factors influencing energy consumption are analyzed earnestly; an adaptive value function is constructed; clustering is optimized by using a particle swarm optimization algorithm; and then routing between clusters is optimized by operating an ant colony algorithm in a cluster head node. Therefore, the energy consumption of a sensor node in a network is equalized; the survival time of the network is prolonged; a path with small communication delay is selected; the flow of the network is equalized; and a utilization ratio of a wireless sensor network for animal breeding environment detection is increased.

Description

technical field [0001] The invention belongs to the technical field of wireless sensor networks, and in particular relates to a wireless sensor network clustering routing method based on particle colony ant colony optimization. The method designed in this patent reduces the energy consumption of the wireless sensor network and prolongs the life cycle of the network by optimizing the cluster routing. Background technique [0002] Wireless sensor networks usually consist of hundreds or thousands of nodes arranged in the sensing area. There are many applications in the fields of industrial control, military, and environmental monitoring, especially in the field of animal breeding environment detection. These nodes are small in size, powered by batteries with limited energy and cannot replenish energy, so efficient use of energy is critical. For wireless sensor networks, the network topology has a great influence on the performance of the network. An excellent topology structur...
