Optimizing Peak Age of Information in Mobile Edge Computing Systems: Analyzing the Impact of Computing Preemption and Non-preemption
The core message of this article is to determine the optimal scheduling policy to minimize the average peak age of information (PAoI) in mobile edge computing (MEC) systems, considering both transmission and computation times. The authors analyze two edge server setups: computing preemption, where a new packet can preempt the current computing process, and non-preemption, where a new packet has to wait until the current one completes computing.
