Embodiment Construction

[0019] The technical solutions in the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0020] The embodiment of the present invention provides a method for selecting an optimal node of an Internet of Things gateway, which includes the following steps:

[0021] S1: Use different network nodes as search particles to form a particle swarm, initialize the particle swarm, randomly initialize the speed and position of each particle, and set the size of the group, the maximum number of iterations, and the maximum speed;

[0022] S2: Calculate the fitness value of each particle according to t...

Abstract

The invention provides an Internet of things gateway optimal node selection method. The method comprises the following steps: forming a particle swarm by taking different network nodes as search particles for initialization; calculating an adaptation value of each particle; calculating a speed of each particle of a next round; calculating a position of the particles of a next round; according to an object function, re-calculating an adaption value of each particle; updating an optimal position of each particle itself, if the current adaption values of the particles are better than adaption values corresponding to their historical optimal positions, taking current positions as new optimal positions; and updating a global optimal position of the swarm, if the adaption value of a current optimal individual is better than the adaption value corresponding to a global historical optimal position, taking the position of such an optimal individual as a new global optimal position. According to the invention, a conventional particle swarm is improved, the improved particle swarm algorithm can more rapidly and accurately select proper nodes as gateways, and the method is more suitable for the dynamic change feature of the Internet of things.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to a method for selecting an optimal node of an Internet of Things gateway. Background technique [0002] The Internet of Things gateway provided by the prior art is prone to data blockage. The Internet of Things is a super-large-scale network. The data transmitted on the Internet of Things can be regarded as massive data. At the same time, the data processing capacity of each network is limited, so it is easy to cause data congestion on the gateway. At this time, using the local optimization method can reduce the degree of congestion to a certain extent, but it cannot fundamentally solve and prevent the occurrence of congestion. If you want to fundamentally solve and prevent congestion, you must start from the source of congestion. Because the data of the Internet of Things flowing from the Internet of Things perception layer actually accounts for the vast majority...
