The computer-implemented method of claim 0, further comprising:

• determining a time Tprocess(x) for executing subtasks ab1 through abn at the edge device;
• determining a time Tprocess(y) for executing subtasks abn+1 through abN at the further edge device;
• determining a time Tmig for communicating abn+1 through abN from the edge device to the further edge device;
• and
• evaluating a sum including Tprocess(x), Tprocess(y), and Tmig in minimizing the total time T′(total).

The computer-implemented method of claim 0, wherein

• Tprocess(x) is determined using factors including
• Tprocess(x)=(b*n)*Cedx/Fedx
• where
• Cedx=a number of processing cycles that the edge device will allocate to processing n subtasks of data size b;
• and
• Fedx=a clock frequency of the edge device;
• and
• Tprocess(y) is determined using factors including
• Tprocess(y)=[b*(n+1˜N)]*Cedy/Fedy
• where
• Cedy=a number of processing cycles that the further edge device will allocate to processing (n+1˜N) subtasks of data size b;
• and
• Fedy=a clock frequency of further edge device.

An Internet of Things (IoT) system comprising:

• one or more information handling systems, wherein the one or more information handling systems include:
• a processor;
• a data bus coupled to the processor;
• and
• a non-transitory, computer-readable storage medium embodying computer program code, the non-transitory, computer-readable storage medium being coupled to the data bus;
• wherein the computer program code included in one or more of the information handling systems is executable by the processor of the information handling system so that the information handling system, alone or in combination with other information handling systems, executes operations comprising:
• receiving a task for execution at an edge device;
• detecting whether a task migration condition exists at the edge device;
• dividing the task into a plurality of subtasks of equal data size;
• and
• migrating at least some of the subtasks to a further edge device for execution.
