Abstract

The present invention provides a method, system and device for Internet of Things service rescheduling. The method includes: extracting the target service set from the service set that can complete the service request according to the service request of the user; using the genetic algorithm model, From the service migration strategy corresponding to the target service set, determine the candidate scheduling scheme of the target service set; for each of the candidate scheduling schemes, use the scheduling cost calculation model to calculate the service scheduling cost of the candidate scheduling scheme; The calculated cost of each of the service scheduling is used as an input parameter, and a target scheduling solution is output from all the candidate scheduling solutions by using a utility evaluation model. In this way, according to the target scheduling plan, the target IoT service that has undergone service migration is scheduled to be executed on the designated hosting device, which can optimize the scheduling method of the IoT service within the coverage of the IoT network, improve resource utilization efficiency and IoT service quality .

Description

technical field [0001] The present invention relates to the technical field of the Internet of Things, in particular, to a method, system and device for rescheduling services of the Internet of Things. Background technique [0002] With the emergence and rapid development of edge computing and micro-service architecture, a large number of IoT devices are deployed at the edge of the network, interconnecting with each other, communicating and collaborating to provide various functions. These functions can be encapsulated and expressed as IoT services, among which, IoT services are hosted on different IoT devices in the network, and different IoT services respond to service requests sent by users in the network in a coordinated manner, such as interactive game requests, video processing requests, etc. Therefore, In the application process of the Internet of Things, it is often necessary to schedule the Internet of Things services hosted on each Internet of Things device in the ...
