Embodiment approach

[0035] One embodiment of the present invention is as follows:

[0036] Step 1, ring domain division

[0037] First, the monitoring area of ​​the sensor network is regarded as a circular domain with a radius of R, and the base station is at the center of the circle. The monitoring area is divided into several ring domains with the base station as the center. The nodes are randomly distributed in the circular domain, and it is assumed that the positions of the sensor nodes are fixed, and both the nodes and the base station know their own position information in advance. Clustered structures such as figure 2 , the density of cluster head nodes is λ 1 , so the average transmission radius of each cluster head node is r 1 :

[0038] r 1 = 2 S πnp - - - ( 1 )

[0039] Among them, n is th...

Abstract

The invention discloses an annulus-based node energy consumption balancing method in a heterogeneous sensor network. The method comprises the following steps of: determining the cluster head level by dividing a monitoring region by rings, and arranging two types of sensor nodes with different hardware configurations in the sensor network, wherein the cluster head uses a communication mode with optimal single hop and multi-hop proportion. In the method, a sensor node energy consumption model is used, based on the difference of the energy consumption increasing speeds when transmitting data packets for different distances, and in combination with the disadvantages and advantages of the single hop and multi-hop communication modes, the single hop and multi-hop optimal proportion related to the radius of the monitoring region in a cluster head mixed communication mode is obtained, the load on the node is balanced, and the lifecycle of a wireless sensor network is prolonged effectively.

Description

technical field [0001] The invention relates to the technical field of wireless communication networks, in particular to a method for balancing energy consumption of nodes in a heterogeneous wireless sensor network. Background technique [0002] Wireless sensor nodes are powered by batteries, and the special working environment (for example: deployed in virgin forests, military battlefields, oceans, etc.) and the huge coverage area of ​​wireless sensor networks determine the irreplaceability of sensor node batteries. Since the premature death of some nodes in the wireless sensor network will cause the paralysis of the entire sensor network communication, the energy saving and energy balance of the sensor nodes are the prerequisites for the effective work of the wireless sensor network. [0003] Solving the energy problem of sensor nodes is realized by designing an efficient and energy-saving routing protocol. Wireless sensor network routing protocols are divided into flat r...
