Simulation of internet of things environment

A simulation node in an Internet of Things (IoT) environment, wherein the IoT environment comprises the simulation node and a cloud server connected by a computerized network, wherein the simulation node comprising:

• a memory;
• and
• a processor, wherein the processor is configured to perform a method comprising:
• selecting a simulated IoT device to simulate from a plurality of simulated IoT devices that are being simulated by the simulation node;
• invoking a real-world model to obtain real-world simulated values;
• determining a simulated behavior of the selected simulated IoT device by invoking a device model and providing the real-world simulated values thereto, wherein the simulated behavior comprises transmitting a message to the cloud server;
• setting a next simulated action of the simulation node to occur at a designated time, wherein the next simulated action is the simulated behavior;
• and
• performing the next simulated action at the designated time.

A computer program product to be executed by a simulation node in an Internet of Things (IoT) environment, wherein the IoT environment comprises the simulation node and a cloud server connected by a computerized network, wherein the computer program product comprising a non-transitory computer readable storage medium retaining program instructions, which program instructions when read by a processor of the simulation node, cause the processor to perform a method comprising:

• selecting a simulated IoT device to simulate from a plurality of simulated IoT devices that are being simulated by the simulation node;
• invoking a real-world model to obtain real-world simulated values;
• determining a simulated behavior of the selected simulated IoT device by invoking a device model and providing the real-world simulated values thereto, wherein the simulated behavior comprises transmitting a message to the cloud server;
• setting a next simulated action of the simulation node to occur at a designated time, wherein the next simulated action is the simulated behavior;
• and
• performing the next simulated action at the designated time.
