Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0019] A method of extending the lifetime of an entire sensor network comprising the steps of:

[0020] 1) Connect a number of solar nodes to collect solar energy in the sensor network, and define that the energy collected by all solar nodes per unit time is the same, and the details of solar nodes are as follows: figure 1 As shown, solar node information includes collected energy E S Information, consumption energy E C information and residual energy E 剩余 information.

[0021] 2) Apply the EC-CKN algorithm in the sensor network, and set K=1.

[0022] Specifically: in the initial state, each solar node broadcasts its remaining energy E to the sensor nodes within its one-hop range 剩余 inform...

Abstract

The invention discloses a method for prolonging the life cycle of a whole sensor network. The method is characterized in that solar energy nodes are added to charge sensor nodes within a communication range of the whole sensor network, and the life cycle of a whole network is prolonged in conjunction with EC-CKN, so that the efficiency of a sensor in industrial application is increased; the energy consumption is lowered; and the node utilization rate is increased.

Description

technical field [0001] The invention relates to a method for extending the life cycle of the entire sensor network, which belongs to the field of energy collection and utilization. Background technique [0002] In large petrochemical plants, the short life cycle of wireless sensor networks is a very important problem, because the energy expenditure caused by communication of all sensor nodes cannot be controlled simultaneously in the whole plant. IWSNs (Industrial Wireless Sensor Networks) have the advantages of easy deployment, small size, high energy efficiency, and flexible sensor nodes. In large petrochemical enterprises, wireless sensor nodes are often used to monitor the environment. However, how to control the entire network life cycle is of great importance. very important meaning. Contents of the invention [0003] In order to solve the problem that the network life cycle is reduced due to communication overhead in the industrial wireless sensor network, the pres...
