Problems solved by technology

[0004] Embodiments of the present invention provide a method and device for balancing the remaining energy of sensor nodes in a sensor network to solve the problem that some sensor nodes consume less energy and some sensor nodes consume more energy during the use of the sensor network. The problem of uneven energy consumption of sensor nodes leads to premature death of a large number of sensor nodes, which leads to communication failures in the sensor network and poor stability of the sensor network.

Abstract

The embodiment of the invention provides a balancing method and device for residual energy of sensor nodes in a sensor network. The method comprises the following steps: calculating a residual energy distributing coefficient of the sensor network; if the residual energy distributing coefficient is greater than a preset balancing coefficient, balancing the sensor nodes in the sensor network; and if the residual energy distributing coefficient of the balanced sensor network is still greater than the preset balancing coefficient, balancing iteration of the sensor network till the residual energy distributing coefficient of the sensor network is smaller than or equal to the preset balancing coefficient. According to the embodiment of the invention, the residual energy of the sensor nodes in the sensor network is uniformly distributed by balancing iteration of the sensor network till the residual energy distributing coefficient of the sensor network is smaller than or equal to the preset balancing coefficient, and the residual energy of the sensor nodes in the sensor network is uniform, so that advanced death of the sensor nodes can be avoided, and the stability of the sensor network is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of sensor networks, and in particular to a method and device for equalizing residual energy of nodes in a sensor network. Background technique [0002] The basic role of Wireless Sensor Networks (WSNs) is to monitor the environment, discover and locate targets in the environment. Due to the low price of sensor nodes, they can be widely used in digital battlefield monitoring, national defense security, medical care, environmental monitoring and other fields. Each sensor node has a sensing range and a communication range. The sensor node can perceive the environmental information within the sensing range and communicate with other nodes within the communication range. The location change of sensor nodes affects coverage, communication energy consumption and information processing. [0003] In sensor networks, for unknown monitoring areas, nodes are usually deployed randomly, but random ...
