Embodiment Construction

[0040] Starting from the characteristics of the wireless sensor network and the clustering routing algorithm, the present invention studies the energy-constrained wireless sensor network clustering routing algorithm. The specific process is described as follows:

[0041] Step 1. Randomly define wireless sensor nodes in a limited area, the initial energy of each node is the same, and define the location of the base station;

[0042] Step 2. List the fitness function of the selected cluster head, specifically:

[0043]

[0044] Where F CH In order to select the fitness function of the cluster head, it is composed of two parts of information representing the remaining energy information and the position information; α∈[0,1] represents the weight, which is the fitness function with The scale factor; Represents the ratio of the average remaining energy of the cluster head node and the non-cluster head node. It is mainly used to evaluate the remaining energy of the node. The larger the ...

Abstract

The invention discloses a wireless sensor network routing energy-saving method with load balancing. The method comprises: step one, a wireless sensor node is defined randomly in a limited area; step two, a fitness functions of cluster head selection is listed; step three, a cluster head is selected by using an improved particle swarm algorithm; step four, the cluster head carries out broadcasting on other nodes to express the identity of the cluster head; step five, a fitness functions of relay node selection is listed; step six, a relay node is selected by using an improved particle swarm algorithm; step seven, a common node sends environment information detected by the common node to the cluster head; step eight, the cluster head carried out data fusion and sends the fused data to the relay node; and step nine, the relay node sends the data to a base station and communication is completed. Compared with the prior art, the provided wireless sensor network routing energy-saving method has the following beneficial effects: high energy consumption of the cluster head in the traditional wireless sensor network can be reduced; the energy consumption of the whole network can be balanced; and the survival period of the whole network can be prolonged.

Description

Technical field [0001] The present invention relates to the field of wireless sensor networks, in particular to a load-balancing wireless sensor network routing energy saving method. Background technique [0002] A wireless sensor network is a self-organizing wireless network composed of a large number of stationary or moving sensors to cooperatively sense and collect the information of the sensed objects in the geographical area covered by the network, and finally send this information to the owner of the network. Because wireless sensor networks are large in scale and work in areas with few people, it is very difficult and expensive to replace batteries. Therefore, the primary goal of designing wireless sensor network routing protocols is to achieve efficient use of energy and prolong the life cycle of the network. [0003] Wireless sensor network routing protocols are generally divided into flat routing protocols and hierarchical routing protocols. Because the hierarchical rout...
