Multitasking resource allocation system and method on internet of things service platform

A computer-implemented method for multitasking resource allocation of Internet of Things (IoT), comprising the following steps:

• receiving resource requests from clients and converting the resource requests into search requests in sequence by a computer-readable storage medium;
• searching a resource list of sensor nodes of a cloud according to search conditions in the search request and obtaining a resource ID of the sensor node that meets the search conditions by the computer-readable storage medium;
• searching a data list of the sensor node and reading a working frequency of the sensor node in the resource list by the computer-readable storage medium;
• comparing the working frequency with a desired frequency in the search conditions by the computer-readable storage medium to determine if buffered data in the data list can meet requirements;
• feeding back the buffered data to the clients by the computer-readable storage medium if the buffered data meets the requirements;
• and
• controlling the sensor nodes to collect data according to the search conditions and priorities of the sensor nodes and sending the collected data to the clients by the computer-readable storage medium if the buffered data cannot meet the requirements;
• the step of controlling comprises the following sub-steps:
• sorting the sensor nodes according to a difference between the working frequency and the highest frequency of each sensor node by the computer-readable storage medium if the buffered data cannot meet the requirements, the highest frequency is the highest working frequency of each sensor node;
• waking up the sensor nodes in sequence according to the priorities thereof and sending the search conditions to each waked sensor node by the computer-readable storage medium, the higher the difference is, the higher the priority of the sensor node is, and the sensor node with the bigger difference between the working frequency and the highest frequency of each sensor node is firstly waked up;
• and
• controlling the waked sensor node to sample data according to a difference between the desired frequency in the search conditions and the working frequency in the data list by the computer-readable storage medium.
