Problems solved by technology

Due to the non-uniform defect in the randomly distributed network topology, the INS algorithm may cause nodes with less energy to be repeatedly selected as representative nodes, resulting in the premature death of some nodes in the network, which greatly shortens the network life.

Embodiment 1

[0030] This embodiment is based on the figure 2 The network topology shown is illustrated. It mainly explains the clustering method when the sink node is far away from the event source. The application network model is as follows:

[0031] 100 sensor nodes are randomly distributed in an area of ​​100m×100m, the network has the following properties:

[0032] The sensor network node is a static non-moving node; the sink node is at (150, 50); the energy of the sink node is not limited, and the geographical location information and initial energy information of the network node can be obtained. For simplicity, set the event source at the center of the region (50, 50). The topological distribution of sensor nodes and sink nodes is as follows: figure 2 shown.

[0033] Assuming that all nodes in the event source perception area report information to the sink node, the information distortion degree of the sink node is the smallest. In the process of dividing the cluster area and...

[0050] This embodiment is based on the image 3 The network topology shown is illustrated. It mainly explains the clustering method when the sink node is close to the event source. The application network model is as follows:

[0051] 100 sensor nodes are randomly distributed in an area of ​​100m×100m, the network has the following properties:

[0052] The sensor network node is a static non-moving node; the sink node is at (50, 50) position; the energy of the sink node is not limited, and the geographical location information and initial energy information of the network node can be obtained. For simplicity, set the event source at the center of the region (50, 50). The topological distribution of sensor nodes and sink nodes is as follows: image 3 shown.

Abstract

The invention discloses a scene adaptive energy balance-based wireless sensor network vector quantization clustering method. The method comprises a method for determining an optimum code book by an exclusive method when a convergent code is far away from an event source, a method for determining the optimum code book by a weighing method when the convergent code is near the event and a method forscreening out the least representative node number by an iterative method. In the method, the least representative node number and the particular position thereof are screened out by taking a residual energy factor of the node into full consideration, utilizing the space correlation properties of the sensor network and adopting a residual energy-based vector quantization method, so that the nodesin an event source perceptual area can cooperate with one another and the aim of balancing the network energy is fulfilled; and the problem that because the energy is too little and the node is selected to be the representative node repeatedly, part of the nodes die untimely, so that the life cycle of the network is greatly prolonged and the resource utilization ratio is greatly improved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, and is a vector quantization clustering method that not only considers the geographical location of nodes in the overall network but also considers the remaining energy of a single node. This method is mainly used in wireless sensor networks, and can effectively prolong the life cycle of the network. Background technique [0002] A sensor network is a network system integrating monitoring, control and wireless communication. Since most sensor nodes are small in size and distributed outdoors, it is difficult to replace batteries for them, so sensor nodes have the characteristics of very limited energy, processing power, storage capacity and communication capacity. How to efficiently use limited energy to maximize the network lifetime is the primary challenge for sensor networks. [0003] In order to eliminate holes in the coverage area, typical sensor networks adopt spatially dens...
